| 3 | Molecular basis underlying rice tiller angle:Current progress and future perspectives显示文摘Crop plant architecture is an important agronomic trait that contributes greatly to crop yield.Tiller angle is one of the most critical components that determine crop plant architecture,which in turn substantially af-fects grain yield mainly owing to its large influence on plant density.Gravity is a fundamental physical force that acts on all organisms on earth.Plant organs sense gravity to control their growth orientation,including tiller angle in rice(Oryza sativa).This review summarizes recent research advances made using rice tiller angle as a research model,providing insights into domestication of rice tiller angle,genetic regulation of rice tiller angle,and shoot gravitropism.Finally,we propose that current discoveries in rice can shed light on shoot gravitropism and improvement of plant tiller/branch angle in other species,thereby contributing to agricultural production in the future. | Wenguang Wang Hengbin Gao Yan Liang Jiayang Li Yonghong Wang | 2022 | Molecular Plant2022，15，1： | 5 |
| 4 | 作物分枝的分子调控研究进展显示文摘分枝的数量及角度是决定作物株型的重要农艺性状。有效分枝数决定着作物的穗数或荚果数,进而决定着作物的产量;而分枝角度与光合效率、种植密度和抗病性密切相关,不仅影响作物的产量,也会影响作物的品质。由于分枝在作物生产中具有十分重要的作用,吸引了越来越多的研究者的注意,多个与分枝性状相关的关键基因被鉴定,分枝数目调控的分子机制研究取得了重要进展。过去的研究表明作物分枝受严格的遗传调控,同时也受环境条件的影响。综述了与作物分枝性状相关的基因克隆、表达、功能和分子调控机理方面的研究进展,以及环境因素对分枝的影响,探讨分枝调控在作物品种改良中的应用。 | 周希萌 付春 马长乐 王兴军 赵传志 | 2021 | 生物技术通报2021，37，3： | 3 |
| 5 | 水稻育种主要目标性状基因挖掘研究进展显示文摘水稻是人类最重要的粮食作物之一,它养育着现今世界近半数人口。现代水稻育种起步于20世纪20年代,在水稻的百年育种进程中,高产、优质、多抗一直是水稻育种领域关注的重点。随着社会经济发展和劳动力成本上涨,水稻经济比较效益出现下降趋势,这促使水稻育种目标逐渐向全过程高效和绿色可持续发展转变。水稻育种的每一次跨越式突破都和目标性状基因资源挖掘紧密相关,因此,充分了解育种主要目标性状的基因挖掘研究进展,对利用现代生物技术进一步挖掘利用优良基因资源指导水稻育种具有重要意义。围绕高产、优质、多抗、高效和绿色等水稻育种的主要目标,综述了各大育种目标性状基因挖掘和利用的研究进展。展望未来,中国水稻育种将逐步培育出稳增提质、环境友好、节水减碳的优良品种,夯实中国在水稻产业的国际领先地位,为全球的粮食安全持续做出贡献。 | 丁文家 胡峻铭 王嘉力 | 2023 | 杂交水稻2023，38，3： | 2 |

| 7 | Pho-view of Auxin:Reversible Protein Phosphorylation in Auxin Biosynthesis,Transport and Signaling显示文摘The phytohormone auxin plays a central role in shaping plant growth and development.With decades of genetic and biochemical studies,numerous core molecular components and their networks,underlying auxin biosynthesis,transport,and signaling,have been identified.Notably,protein phosphorylation,catalyzed by kinases and oppositely hydrolyzed by phosphatases,has been emerging to be a crucial type of post-translational modification,regulating physiological and developmental auxin output at all levels.In this review,we comprehensively discuss earlier and recent advances in our understanding of genetics,biochemistry,and cell biology of the kinases and phosphatases participating in auxin action.We provide insights into the mechanisms by which reversible protein phosphorylation defines developmental auxin responses,discuss current challenges,and provide our perspectives on future directions involving the integration of the control of protein phosphorylation into the molecular auxin network. | Shutang Tan Christian Luschnig Jiri Friml | 2021 | Molecular Plant2021，14，1： | 1 |
| 8 | A major vernalization-independent QTL for tiller angle on chromosome arm 2BL in bread wheat显示文摘Tiller angle(TA)strongly influences plant architecture and grain yield in cereals.However,the genetic basis of TA in wheat is largely unknown.We identified three TA-related quantitative trait loci(QTL).One of them was QTa.sau-2 B-769,a major QTL localized on chromosome arm 2 BL.QTa.sau-2 B-769 was detected in seven environments,explaining 18.1%–51.1%of phenotypic variance.We developed a linked Kompetitive Allele-Specific Polymerase chain reaction(KASP)marker,KASP-AX-108792274,to further validate this locus in three additional populations in multiple environments.QTa.sau-2 B-769 increased TA by up to 24.9%in these populations.There were significant and positive correlations between TA and flag leaf angle(FLANG).However,TA was not correlated with plant height or anthesis date,suggesting that expression of QTa.sau-2 B-769 is independent of vernalization.Traes CS2 B01 G583800,a gene known to be involved in leaf angle regulation,was identified as the most likely candidate gene for QTa.sau-2 B-769.These results enrich our understanding of the mechanisms regulating wheat TA at maturity and may support precise mapping and cloning of gene(s)underlying QTa.sau-2 B-769. | Jiajun Liu Jieguang Zhou Huaping Tang Yang Tu Yang Mu Lulu Gou Qiantao Jiang Yaxi Liu Guoyue Chen Jirui Wang Pengfei Qi Wei Li Yunfeng Jiang Zehong Yan Houyang Kang Yuming Wei Xiujin Lan Youliang Zheng Jian Ma | 2022 | The Crop Journal2022，10，1： | 0 |
| 9 | Divergence of three BRX homoeologs in Brassica rapa and its effect on leaf morphology显示文摘The leafy head characteristic is a special phenotype of Chinese cabbage resulting from artificial selection during domestication and breeding.BREVIS RADIX(BRX)has been suggested to control root elongation,shoot growth,and tiller angle in Arabidopsis and rice.In Brassica rapa,three BrBRX homoeologs have been identified,but only BrBRX.1 and BrBRX.2 were found to be under selection in leaf-heading accessions,indicating their functional diversification in leafy head formation.Here,we show that these three BrBRX genes belong to a plant-specific BRX gene family but that they have significantly diverged from other BRX-like members on the basis of different phylogenetic classifications,motif compositions and expression patterns.Moreover,although the expression of these three BrBRX genes differed,compared with BrBRX.3,BrBRX.1,and BrBRX.2 displayed similar expression patterns.Arabidopsis mutant complementation studies showed that only BrBRX.1 could rescue the brx root phenotype,whereas BrBRX.2 and BrBRX.3 could not.However,overexpression of each of the three BrBRX genes in Arabidopsis resulted in similar pleiotropic leaf phenotypes,including epinastic leaf morphology,with an increase in leaf number and leaf petiole length and a reduction in leaf angle.These leaf traits are associated with leafy head formation.Further testing of a SNP(T/C)in BrBRX.2 confirmed that this allele in the heading accessions was strongly associated with the leaf-heading trait of B.rapa.Our results revealed that all three BrBRX genes may be involved in the leaf-heading trait,but they may have functionally diverged on the basis of their differential expression. | Yuanyuan Zhang Jianli Liang Xu Cai Haixu Chen Jian Wu Runmao Lin Feng Cheng Xiaowu Wang | 2021 | Horticulture Research2021，8，1： | 0 |
