| 1 | Maize-soybean strip intercropping: Achieved a balance between high productivity and sustainability显示文摘Intercropping is one of the most vital practice to improve land utilization rate in China that has limited arable land resource. However, the traditional intercropping systems have many disadvantages including illogical field lay-out of crops, low economic value, and labor deficiency, which cannot balance the crop production and agricultural sustainability. In view of this, we developed a novel soybean strip intercropping model using maize as the partner, the regular maize-soybean strip intercropping mainly popularized in northern China and maize-soybean relay-strip intercropping principally extended in southwestern China. Compared to the traditional maize-soybean intercropping systems, the main innovation of field lay-out style in our present intercropping systems is that the distance of two adjacent maize rows are shrunk as a narrow strip, and a strip called wide strip between two adjacent narrow strips is expanded reserving for the growth of two or three rows of soybean plants. The distance between outer rows of maize and soybean strips are expanded enough for light use efficiency improvement and tractors working in the soybean strips. Importantly, optimal cultivar screening and increase of plant density achieved a high yield of both the two crops in the intercropping systems and increased land equivalent ratio as high as 2.2. Annually alternative rotation of the adjacent maize-and soybean-strips increased the grain yield of next seasonal maize, improved the absorption of nitrogen, phosphorus, and potasium of maize, while prevented the continuous cropping obstacles. Extra soybean production was obtained without affecting maize yield in our strip intercropping systems, which balanced the high crop production and agricultural sustainability. | DU Jun-bo HAN Tian-fu GAI Jun-yi YONG Tai-wen SUN Xin WANG Xiao-chun YANG Feng LIU Jiang SHU Kai LIU Wei-guo YANG Wen-yu | 2018 | Journal of Integrative Agriculture2018，17，4： | 34 |
| 2 | Feeding of Riptortus pedestris on soybean plants, the primary cause of soybean staygreen syndrome in the Huang-Huai-Hai river basin显示文摘Staygreen syndrome or Zhengqing in soybean has recently become a major issue for Chinese growers in the Huang-Huai-Hai river basin.Although previous studies revealed that staygreen can be induced when pods/seeds are damaged, it is unknown whether virus infection or insect infestation causes staygreen.To determine whether viral infection causes staygreen, a survey of soybean staygreen incidence in the Huang-Huai-Hai river basin was conducted in 2016 and 2017.Diseased samples were collected and analyzed using DAS-ELISA for Soybean mosaic virus, Watermelon mosaic virus, Bean pod mottle virus, Cucumber mosaic virus, and Bean common mosaic virus.The survey showed that the severity of soybean staygreen syndrome was most prevalent in Beijing, Henan, Shaanxi, and some parts of Shandong provinces, with yield losses from 0 to nearly 100%, but only a small fraction of samples were positive for the tested viruses.A field cage experiment and an insecticide treatment field trial were conducted to determine the contribution of the bean bug, Riptortus pedestris, to staygreen incidence.The field cage experiment showed that R.pedestris treatment resulted in shorter plants, more empty pods, increased numbers of abnormal seeds, and decreased yields.The field experiment showed that there were fewer R.pedestris and less soybean staygreen incidence in fields treated with insecticide than in untreated control fields.Together, these results suggest that R.pedestris infestation rather than virus infection induces staygreen syndrome and that growers in this region can mitigate staygreen syndrome via bean bug control. | Kai Li Xinxin Zhang Jianqiu Guo Hannah Penn Tingting Wu Lin Li Hong Jiang Lidan Chang Cunxiang Wu Tianfu Han | 2019 | The Crop Journal2019，7，3： | 30 |
| 3 | Physiological and molecular studies of staygreen caused by pod removal and seed injury in soybean显示文摘Leaves provide substances and signals for pod and seed development in soybean.However,the regulatory feedbacks of pod and seed to leaf development remain unclear.We investigated the effects of pod and seed on leaf senescence by conducting pod removal and seed injury experiments.Pod removal and seed injury delayed leaf senescence and caused the staygreen phenotype of leaves.There were dosage effects of pod number on the extent of staygreen in depodded plants.The concentrations of chlorophyll(SPAD value,an index of relative chlorophyll content),soluble protein,and soluble sugar in the leaves of depodded plants were higher than those of intact plants.During seed development,the content of IAA decreased,while that of ABA increased.This trend was more pronounced in intact than in depodded and seed-injured plants.The GA3/ABA ratio decreased gradually in all treatments.The content of GA3 was relatively stable and was higher in intact than in depodded plants.The expression levels of four senescence-related genes,Gm SARK,Gm SGR1,Gm CYN1,and Gm NAC,declined in depodded or seed-injured treatments and were positively correlated with the number of leaves retained on plants.Gm FT2 a,the major flowering-promoting gene,was expressed at a higher level while E1,a key flowering inhibitory gene,was expressed at a lower level in depodded than in intact plants.We propose that the pod or seed can regulate leaf development.When the seed is aborted owing to disease infection or pest attack,the leaves stay green because of the absence of the seed signals for senescence. | Xinxin Zhang Min Wang Tingting Wu Cunxiang Wu Bingjun Jiang Changhong Guo Tianfu Han | 2016 | The Crop Journal2016，4，6： | 23 |
| 4 | Current research on soybean pest management in China显示文摘Pest is one of the important factors affecting soybean yield and quality. Until now, 404 species on soybean have been known based on literature review and a large scale survey. More than 20 key pests occur every year and are causing serious damage. In 3 different ecoregions(Northern ecoregion, Huang-Huai-Hai ecoregion and Central south ecoregion), pests occurrence and damage styles show a variety of regional characteristics. Soybean pests occurrence from north to south were shown as follow: from large pests to small pests, from chewing pests to sucking pests, from low reproductive rate and less generation pests to high reproductive rate and more generation pests. Soybean pest management is mainly based on resistant breeding, combining with monitoring, plant quarantine, cultural, biological, physical, mechanical and chemical controls in China. Although pesticides play an important role in practice, the absence of reasonable use has threatened sustainability of China's soybean production. Soybean integrated pest management is not the only strategy, and it still needs improvement and development, but it's the best alternative for pest control. It can be expected that integrated pest management will remain as the main strategy for soybean pest control in future. Further innovation of green prevention and control technology will also become a focus of future research in view of new pest problems brought about by crop restructuring, agricultural system change and global climate change. Integration of above technologies will reduce the harm of pests and production costs as well as improving soybean production capacity. In this review, research progress of Chinese soybean pest and its management was summarized and some suggestions were provided to adapt for soybean pest management under current situation. | Yu Gao Shusen Shi Menglei Xu Juan Cui | 2018 | Oil Crop Science2018，3，4： | 22 |
| 5 | 双价抗虫转基因大豆抗苜蓿夜蛾分析(英文)显示文摘[Objective] The aim of the research was to analyze the resistance of binary insect-resistant transgenic soybean to Heliothis viriplaca.[Method]In this experiment, resistance analysis of the stabilized binary insect-resistant transgenic soybean to Heliothis viriplaca was conducted in lab and in field conditions.[Result] The results indicated that the leaves of insect-resistant transgenic soybeans T5-150 and T5-195 showed lighter damage than those of non-transgenic soybeans. Meanwhile, the Heliothis viriplaca larvae fed on leaves of these two transgenic soybeans were characterized by less leaf consumption, shortening survival day, slower development and less pupation.[Conclusion]It was concluded that insect-resistance of transgenic soybean to Heliothis viriplaca was increased dramatically and the research provided a reference for selecting binary insect-resistant transgenic soybean to Heliothis viriplaca. | 杨向东 郭东全 包绍君 赵桂兰 康岭生 钱雪燕 尹爱萍 邢国杰 | 2008 | Agricultural Science & Technology2008，9，3： | 21 |

| 7 | Screening Chinese soybean genotypes for Agrobacterium-mediated genetic transformation suitability显示文摘The Agrobacterium-mediated transformation system is the most commonly used method in soybean transformation.Screening of soybean genotypes favorable for Agrobacterium-infection and tissue regeneration is the most important step to establish an efficient genetic transformation system.In this study,twenty soybean genotypes that originated from different soybean production regions in China were screened for transient infection,regeneration capacity,and stable transgenic efficiency.Three genotypes,Yuechun 04-5,Yuechun 03-3,and Tianlong 1,showed comparable stable transgenic efficiencies with that of the previously reported American genotypes Williams 82 and Jack in our experimental system.For the Tianlong 1,the average stable transformation efficiency is 4.59%,higher than that of control genotypes(Jack and Williams 82),which is enough for further genomic research and genetic engineering.While polymerase chain reaction(PCR),LibertyLink strips,and β-glucuronidase(GUS) staining assays were used to detect the insertion and expression of the transgene,leaves painted with 135 mg/L Basta could efficiently identify the transformants. | Zhang-yue SONG Jing-luan TIAN Wei-zhe FU Lin LI Ling-hong LU Lian ZHOU Zhi-hui SHAN Gui-xiang TANG Hui-xia SHOU | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，4： | 17 |
| 8 | Simultaneous changes in seed size, oil content and protein content driven by selection of SM/EEIhomologues during soybean domestication显示文摘Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed.Soybean domestication involved parallel increases in seed size and oil content,and a concomitant decrease in protein content.However,science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes.Here,re-sequencing data from>800 genotypes revealed a strong selection during soybean domestication on GmSWEETlOa.The selection of GmSWEETlOa conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content.The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans.Moreover,GmSWEETlOb was found to be functionally redundant with its homologue GmSWEETlOa and to be undergoing selection in current breeding,leading the the elite allele GrnSWEETlOb,a potential target for present-day soybean breeding.Both GmSWEETlOa and GmSWEETlOb were shown to transport sucrose and hexose,contributing to sugar allocation from seed coat to embryo,which consequently determines oil and protein contents and seed size in soybean.We conclude that past selection of optimal GmSWEETlOa alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEETlOb may further improve the yield and seed quality of modern soybean cultivars. | Shoudong Wang Shulin Liu Jie Wang Kengo Yokosho Bin Zhou Ya-Chi Yu Zhi Liu Wolf BFrommer Jian Feng Ma Li-Qing Chen Yuefeng Guan Huixia Shou Zhixi Tian | 2020 | National Science Review2020，7，11： | 17 |
| 9 | Calcium-binding ability of soy protein hydrolysates显示文摘This present study investigated the ability of various soy protein hydrolysates(SPHs)in binding calcium.It was demonstrated that the amount of Ca-bound depended greatly on the SPHs obtained using different proteases,which included:neutrase, flavourzyme,protease M and pepsin.The maximum level of Ca-bound(66.9 mg/g)occurred when protease M was used to hydrolyze soy protein.Peptide fragments exhibiting high Ca-binding capacity had molecular weights of either 14.4 or 8-9 kDa.The level of Ca-bound increased linearly with the increment of carboxyl content in SPHs,and further deamidation on SPHs from protease M improved Ca-binding of the hydrolysate. | Xiao Lan Bao Mei Song Jing Zhang Yang Chen Shun Tang Guo | 2007 | Chinese Chemical Letters2007，18，9： | 14 |
| 10 | Photoperiodism dynamics during the domestication and improvement of soybean显示文摘Soybean(Glycine max) is a facultative short-day plant with a sensitive photoperiod perception and reaction system, which allows it to adjust its physiological state and gene regulatory networks to seasonal and diurnal changes in environmental conditions. In the past few decades, soybean cultivation has spread from East Asia to areas throughout the world. Biologists and breeders must now confront the challenge of understanding the molecular mechanism of soybean photoperiodism and improving agronomic traits to enable this important crop to adapt to geographical and environmental changes. In this review, we summarize the genetic regulatory network underlying photoperiodic responses in soybean. Genomic and genetic studies have revealed that the circadian clock, in conjunction with the light perception pathways, regulates photoperiodic flowering. Here, we provide an annotated list of 844 candidate flowering genes in soybean, with their putative biological functions. Many photoperiod-related genes have been intensively selected during domestication and crop improvement. Finally, we describe recent progress in engineering photoperiod-responsive genes for improving agronomic traits to enhance geographic adaptation in soybean, as well as future prospects for research on soybean photoperiodic responses. | Sheng-Rui Zhang Huan Wang Zhongyu Wang Yao Ren Lifang Niu Jun Liu Bin Liu | 2017 | Science China(Life Sciences)2017，60，12： | 13 |
| 11 | Isolation of bacteria from fermented food and grass carp intestine and their efficiencies in improving nutrient value of soybean meal in solid state fermentation显示文摘Background: Soybean meal is an excellent and cost-effective protein source; however, its usage is limited in the piglet due to the presence of anti-nutritional factors and the antigens glycinin and β-conglycinin. The objective of the current study was to screen and select for bacteria that can be efficiently adopted to ferment soybean meal in order to solve this problem.Results: Bacteria were isolated from fermented soy foods and the grass carp intestine, and strains selected for high protease, cellulase and amylase activities. The isolated bacteria were characterized as Bacillus cereus, Bacillus subtilis and Bacilus amyloliquefacien, respectively. Fermentation with food-derived Isolate-2 and fish-derived F-9 increased crude protein content by 5.32% and 8.27%, respectively; improved the amino acid profile by increasing certain essential amino acids, broke down larger soy protein to 35 k Da and under, eliminated antigenicity against glycinin and β-conglycinin, and removed raffinose and stachyose in the soybean meal following a 24-h fermentation.Conclusions: Our results suggest these two B. amyloliquefaciens bacteria can efficiently solid state ferment soybean meal and ultimately produce a more utilizable food source for growing healthy piglets. | Samantha Medeiros Jingjing Xie Paul W.Dyce Hugh Y.Cai Kees De Lange Hongfu Zhang Julang Li | 2018 | Journal of Animal Science and Biotechnology2018，9，3： | 12 |
| 12 | Overexpression of G10-EPSPS in soybean provides high glyphosate tolerance显示文摘Glyphosate is a highly efficient, broad-spectrum nonspecific herbicide that inhibits the 5-enolpyruvylshikimate-3-phosphate synthase(EPSPS)-mediated pathway of shikimic acid. The screening of glyphosate-resistant EPSPS gene is a major means for the development of new genetically modified glyphosate-resistant transgenic crop. Currently, the main commercialized glyphosate-resistant soybean contains glyphosate-resistant gene CP4-EPSPS. In this study, a G10-EPSPS gene was reported providing glyphosate resistance in Zhongdou 32. Here, G10-EPSPS gene was introduced into soybeans through Agrobacterium-mediated soybean cotyledon node. PCR, Southern blotting, semi-quantitative RT-PCR, qRT-PCR, and Western blotting were used, and the results revealed that G10-EPSPS had been integrated into the soybean genome and could be expressed steadily at both mRNA and protein levels. In addition, glyphosate resistance analysis showed that the growth of transgenic soybean had not been affected by concentrations of 900 and 2 700 g a.e. ha–1 of glyphosate. All the results indicated that G10-EPSPS could provide high glyphosate resistance in soybeans and be applied in production of glyphosate-resistant soybean. | XIAO Pei-ying LIU Yi CAO Yue-ping | 2019 | Journal of Integrative Agriculture2019，18，8： | 11 |
| 13 | Molecular mechanisms for the photoperiodic regulation of flowering in soybean显示文摘Photoperiodic flowering is one of the most important factors affecting regional adaptation and yield in soybean(Glycine max). Plant adaptation to long-day conditions at higher latitudes requires early flowering and a reduction or loss of photoperiod sensitivity;adaptation to short-day conditions at lower latitudes involves delayed flowering, which prolongs vegetative growth for maximum yield potential. Due to the influence of numerous major loci and quantitative trait loci(QTLs), soybean has broad adaptability across latitudes. Forward genetic approaches have uncovered the molecular basis for several of these major maturity genes and QTLs. Moreover, the molecular characterization of orthologs of Arabidopsis thaliana flowering genes has enriched our understanding of the photoperiodic flowering pathway in soybean. Building on early insights into the importance of the photoreceptor phytochrome A, several circadian clock components have been integrated into the genetic network controlling flowering in soybean: E1, a repressor of FLOWERING LOCUS T orthologs, plays a central role in this network. Here, we provide an overview of recent progress in elucidating photoperiodic flowering in soybean, how it contributes to our fundamental understanding of flowering time control, and how this information could be used for molecular design and breeding of high-yielding soybean cultivars. | Xiaoya Lin Baohui Liu James LWeller Jun Abe Fanjiang Kong | 2021 | Journal of Integrative Plant Biology2021，63，6： | 11 |
| 14 | A seed-specific AP2-domain transcription factor from soybean plays a certain role in regulation of seed ger-mination显示文摘Plant seed development and germination are under strict temporal and spatial regulation, and tran-scription factors play important roles in this regulation. In the present study we identified an EST ex-pressed specifically in the developing soybean seeds. The full length of the gene was obtained through further RACE analysis and the gene was named GmSGR. Sequence analysis revealed that this gene belonged to the AP2/ERF transcription factor family. Its AP2 domain had the highest similarity with that of the A-3 member AtABI4 of DREB subgroup in the AP2/ERF family in Arabidopsis. GmSGR did not exhibit transcriptional activation activity in the yeast assay system. GmSGR was overexpressed in Arabidopsis and the germination rates of the transgenic seeds were significantly higher than that of the wild type seeds under higher concentrations of ABA and glucose respectively. However, the germina-tion rates of the transgenic seeds were lower than that of control under salt stress. The expression of AtEm6 and AtRD29B was higher in the seedlings of the transgenic plants than that in the wild-type seedlings. These results suggest that GmSGR may confer reduced ABA sensitivity and enhanced salt sensitivity to the transgenic seeds through regulating the expression of AtEm6 and AtRD29B genes. | WANG ChunMei, WANG HuiWen, ZHANG JinSong & CHEN ShouYi National Key Laboratory of Plant Genomics, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, Bei-jing 100101, China | 2008 | Science China(Life Sciences)2008，51，4： | 11 |
| 15 | Assessing the numbers of SNPs needed to establish molecular IDs and characterize the genetic diversityof soybean cultivars derived from Tokachi nagaha显示文摘The development of a core set of SNP molecular markers that could be widely used in soybean genetic research would greatly facilitate research into the genetic diversity of soybean.We conducted an analysis of Tokachi nagaha and 137 of its descendant soybean cultivars using 4044 SNP markers with the goal of determining the appropriate number of single-nucleotide polymorphisms(SNPs)needed to construct unambiguous molecular IDs and characterize genetic diversity based on a genetic distance matrix correlation method.When the number of SNPs was held constant,the number of accession pairs that could be distinguished increased as the polymorphism informative content(PIC)value of the SNPs increased.A core panel of 20 selected SNPs from 11 linkage groups with a mean PIC value of 0.3703 and a range of 0.3640–0.3749 was able to identify almost all of the accession pairs in our study[9445 pairs(99.92%)].The eight accession pairs that could not be identified with this core SNP set all originated from the same province and some of them had the same parental cultivars.The molecular IDs of the 138 accessions were constructed using the core 20 SNPs.It is known that both the number of SNPs and PIC values should be considered when SNPs are selected for use in the analysis of genetic diversity.In this study,when the PIC value was 0.3460,the correlation coefficient between the genetic distance matrices associated with a panel of 200 SNPs and the total population was>0.800,indicating satisfactory correlation.Our high-accuracy,high-resolution core SNP panel for germplasm fingerprinting and our findings about assessing genetic diversity will likely markedly improve the management and utilization efficiency of soybean germplasm resources. | Zhangxiong Liu Jun Li Xuhong Fan Nang Myint Phyu Sin Htwe Shuming Wang Wen Huang Jiyu Yang Lili Xing Lijun Chen Yinghui Li Rongxia Guan Ruzhen Chang Dechun Wang Lijuan Qiu | 2017 | The Crop Journal2017，5，4： | 10 |

| 17 | Warming decreases photosynthates and yield of soybean [Glycine max(L.) Merrill] in the North China Plain显示文摘Understanding the responses of field crops such as soybean to climate warming is critical for economic development and adaptive management of food security. A field warming experiment was conducted using infrared heaters to investigate the responses of soybean phenology, photosynthetic characteristics, and yield to climate warming in the North China Plain. The results showed that 0.4 °C and 0.7 °C increases in soybean canopy air and soil temperature advanced anthesis stage by 3.8 days and shortened the length of entire growth stage by 4.5 days. Warming also decreased the leaf photosynthetic rate by 6.6% and 10.3% at the anthesis and seed filling stages, respectively, but increased the leaf vapor pressure deficit by 9.4%, 15.7%, and 14.1% at the anthesis, pod setting, and seed filling stages,respectively. However, leaf soluble sugar and starch were decreased by 25.6% and 20.5%,respectively, whereas stem soluble sugar was reduced by 12.2% at the anthesis stage under experimental warming. The transportation amount of leaf soluble sugar and contribution rate of transportation amount to seed weight were reduced by 58.2% and 7.7%, respectively,under warming. As a result, warming significantly decreased 100-seed weight and soybean yield by 20.8% and 45.0%, respectively. Our findings provide better mechanistic understanding of soybean yield response to climate warming and could be helpful for forecasting soybean yield under future climate warming conditions. | Lixia Zhang Lili Zhu Mengyang Yu Mingxing Zhong | 2016 | The Crop Journal2016，4，2： | 9 |
| 18 | Erosion effect on the productivity of black soil in Northeast China显示文摘Continuous soil erosion has caused serious land degradation in the black soil area of Northeast China. The primary objective of this study was to determine the effects of accelerated erosion on soil productivity, as measured by soybean (Glycine max L. Merr.) yields. Eight erosion levels, 0, 10, 20, 30, 40, 50, 60, and 70 cm, were simulated by imitating the integrated process of natural erosion and tillage activity. Each erosion level had two sub-treatments: conventional fertilization and no fertilization. Soil erosion was found to affect survival probability and to cause remarkable reductions in the Leaf Area Index (LAI), plant height, pod number, biomass, and yield. Soybean yield was exponentially decreased with the increase of soil erosion depth. Compared to erosion depth of 0 cm, erosion levels of 10, 20, 30, 40, 50, 60, and 70 cm experienced reductions in soybean yield by 28.8%, 37.8%, 43.5%, 52.6%, 53.1%, 52.9%, and 64.1% respectively when fertilized whereas the reductions at those levels were 32.6%, 42.2%, 53.0%, 54.0%, 65.8%, 69.7%, and 72.6%, respectively, when unfertilized. At the erosion depths of 10, 20, 30, 40, 50, 60, and 70 cm, the yield reductions per 10 cm of soil eroded when fertilized were 28.8%, 18.9%, 14.5%, 13.2%, 10.6%, 8.8%, and 9.2%, averaged 14.9%, but when unfertilized they were 32.6%, 21.1%, 17.7%, 13.5%, 13.2%, 11.6%, and 10.4%, averaged 17.1%. The results also showed that chemical fertili zers could enhance the yields of eroded soil, but could not recover the yields to the pre-erosion level. Additionally, the results indicated that the primary reason for the decrease in soybean yield with increasing erosion depth was the loss of soil organic matter, soil N and P. These results may aid in selecting effective soil erosion control strategy, forecasting land degradation, establishing soil erosion tolerance, and evaluating the economic cost of soil erosion in the black soil region in Northeast China. | WANG ZhiQiang LIU BaoYuan WANG XuYan GAO XiaoFei LIU Gang | 2009 | Science China Earth Sciences2009，52，7： | 9 |
| 19 | Soybean AP1 homologs control flowering time and plant height显示文摘Flowering time and plant height are key agronomic traits that directly affect soybean(Glycine max)yield.APETALA1(AP1)functions as a class A gene in the ABCE model for floral organ development,helping to specify carpel,stamen,petal,and sepal identities.There are four AP1 homologs in soybean,all of which are mainly expressed in the shoot apex.Here,we used clustered regularly interspaced short palindromic repeats(CRISPR)–CRISPR-associated protein 9 technology to generate a homozygous quadruple mutant,gmap1,with loss-of-function mutations in all four GmAP1 genes.Under short-day(SD)conditions,the gmap1 quadruple mutant exhibited delayed flowering,changes in flower morphology,and increased node number and internode length,resulting in plants that were taller than the wild type.Conversely,overexpression of GmAP1a resulted in early flowering and reduced plant height compared to the wild type under SD conditions.The gmap1 mutant and the overexpression lines also exhibited altered expression of several genes related to flowering and gibberellic acid metabolism,thereby providing insight into the role of GmAP1 in the regulatory networks controlling flowering time and plant height in soybean.Increased node number is the trait with the most promise for enhancing soybean pod number and grain yield.Therefore,the mutant alleles of the four AP1 homologs described here will be invaluable for molecular breeding of improved soybean yield. | Liyu Chen Haiyang Nan Lingping Kong Lin Yue Hui Yang Qingsong Zhao Chao Fang Haiyang Li Qun Cheng Sijia Lu Fanjiang Kong Baohui Liu Lidong Dong | 2020 | Journal of Integrative Plant Biology2020，62，12： | 9 |
| 20 | 大豆DNA导入玉米后代植株蛋白质和油分的分析(英文)显示文摘[Objective] The experiment was aimed to explore character variation between different families after DNA introduction and select variant plants with good stability. [Method] The method of pollen-tube-pathway was used to introduce total DNA of soybean into normal maize inbred line 7313 for selecting generation by generation. When field characters of maize, grain colors, grain traits and panicle axis colors were stable, the crude protein, gliadin, glutelin and oil content of grains which were selected from variant strains were detected and compared. [Result] The grain crude protein, gliadin, glutelin and oil content of line 26h-4-3 were significantly different from these of control treatment. The increments of D3 and D4 generation were 10.34% and 26.70%, 6.58% and 6.28%, 15.09% and 70.34%, 55.82% and 51.52% respectively. All indexes of line 26h-3-1 were also higher than these of control treatment and the increments of D3 and D4 generation were 5.67% and 21.63%,1.91% and 2.31%, 10.85% and 62.27%,22.49% and 9.67%. [Conclusion] The crude protein, gliadin, glutelin and oil content of variant line 26h-4-3 and 26h-3-1 were stable, so variant line 26h-4-3 and 26h-3-1 were excellent variant strains which satisfied the requirement of high protein breeding. | 张慧英 田夏红 冯锐 刘爱花 | 2008 | Agricultural Science & Technology2008，9，6： | 8 |
