1QTL mapping in A-genome diploid Asiatic cotton and their congruence analysis with AD-genome tetraploid cotton in genus Gossypium显示文摘Asiatic cotton(Gossypium arboreum L.) is an Old World cultivated cotton species.The sinense race was planted extensively in China.Due to the advances in spinning technology during the last century,the species was replaced by the New World allotetraploid cotton G.hirsutum L.Gossypium arboreum is still grown in India and Pakistan and also used as an elite in current cotton breeding programs.In addition,G.arboreum serves as a model for genomic research in Gossypium.In the present study,we generated an A-genome diploid cotton intraspecific genetic map including 264 SSR loci with three morphological markers mapped to 13 linkage groups.The map spans 2,508.71 cM with an average distance of 9.4 cM between adjacent loci.A population containing 176 F2:3 families was used to perform quantitative trait loci(QTL) mapping for 17 phenotypes using Multiple QTL Model(MQM) of MapQTL ver 5.0.Overall,108 QTLs were detected on 13 chromosomes.Thirty-one QTLs for yield and its components were detected in the F2 population.Forty-one QTLs for yield and its components were detected in the F2:3 families with a total of 43 QTLs for fiber qualities.Two QTLs for seed cotton weight/plant and lint index and three QTLs for seed index were consistently detected both in F2 and F2:3.Most QTLs for fiber qualities and yields were located at the same interval or neighboring intervals.These results indicated that the negative correlation between fiber qualities and yield traits may result from either pleiotropic effect of one gene or linkage effects of multiple closely linked genes.Xuexia Ma Yezhang Ding Baoliang Zhou Wangzhen Guo Yanhui Lv Xiefei Zhu Tianzhen Zhang 2008Journal of Genetics and Genomics2008,35,12:5
2Inheritance of resistance to Helicoverpa armigera of 3 kinds of transgenic Bt strains available in upland cotton in China显示文摘There are 3 kinds of transgenic Bt strains, Shanxi 94-24, Zhongxin 94, and R19, in upland cotton in China. Their transgenic Bt insect-resistance cultivars or hybrids have been developed and grown by farmers. Genetic studies indicate that the resistance of the 3 transgenic Bt cotton strains to Helicoverpa armigera is controlled by one pair of non-allelic dominant genes. Linkage relationship between the resistant genes of R19 and Shanxi 94-24 transgenic Bt strains shows that they may be inserted in the same chromosome. FT hybrids crossed among the 3 strains show that high levels of protection from feeding damage are the same as that of their parents. Therefore, there is no co-suppression phenomenon in many transgenic plants. The results presented here afford a fundamental reliance in developing transgenic Bt insect-resistant cultivars and exploiting the heterosis of hybrids in upland cotton.TANG Canming SUN Jing ZHU Xiefei GUO Wangzhen ZHANG Tianzhen SHEN Jinliang GAO Congfen ZHOU Weijun CHEN Zhixian GUO Sandui 2000Chinese Science Bulletin2000,45,4:3
3Variation induced by DNA rearrangement in a transgenic Bt+CpTI cotton strain显示文摘In the development, of transgenic Bt + CpTI cotton cultivars, one male and female sterile mutant has been found in a homozygous T4 strain in our laboratory. The mutant plant, as well as its leaves, buds and flowers, is only 1/2-1/3 as large as that of the wild transgenic Bt + CpTI bivalant cotton plants. Cytological observation found that the chromosome number of the mutant is 2n=52; however, there are 4-8 univalents observed in meiosis I of pollen mother cells. Laboratory bioassay indicated that the mutant was highly resistant to bollworm as the wild plants. PCRamplification revealed that Bt and CpTl genes in the mutant were still intactly inserted. However, small deletion of flanked area had been observed in the mutant by Southern blotting analysis. So it is proposed that the mutant pheno-type might result from either the DNA deletion or T-DNA transferring in plant genome. No such report has been presented that the rearrangement of chromosome structure in a homozygous transgenic line occurred.Wangzhen Guo Tianzhen Zhang Xiefei Zhu Xiaoling Yuan 2001Chinese Science Bulletin2001,46,7:2

14Genomic insights into the genetic basis of cotton breeding in China显示文摘The excellent Upland cotton(Gossypium hirsutum)cultivars developed since 1949 have made a huge contribution to cotton production in China,the world's largest producer and consumer of cotton.However,the genetic and genomic basis for the improvements of these cotton cultivars remains largely unclear.In this study,we selected 16 Upland cotton cultivars with important historical status in Chinese cotton breeding and constructed a multiparent,advanced generation,intercross(MAGiC)population comprising 920 recombinant inbred lines.A genome-wide association study using the MAGIC population identified 54 genomic loci associated with lint yield and fiber quality.Of them,25(46.30%)pleiotropic genomic loci cause simultaneous changes of lint yield and/or fiber quality traits,revealing complex trade-offs and linkage drags in Upland cotton agronomic traits.Deep sequencing data of 11 introduced ancestor cultivars and publicly available resequencing datasets of 839 cultivars developed in China during the past 70 years were integrated to explore the historical distribution and origin of the elite or selected alleles.Interestingly,85%oftheseelitealleles were selectedandfixed fromdifferent Americanancestors,consistentwithcotton breeding practices in China.However,seven elite alleles of native origin that are responsible for Fusarium wilt resistance,early maturing,good-quality fiber,and other characteristics were not found in American an-cestors but have greatly contributed to Chinese cotton breeding and wide cultivation.Taken together,these results provide a genetic basis for further improving cotton cultivars and reveal that the genetic composition of Chinese cotton cultivars is narrow and mainly derived from early introduced American varieties.Yiqian Li Zhanfeng Si Guoping Wang Zhuolin Shi Jinwen Chen Guoan Qi Shangkun Jin Zegang Han Wenhao Gao Yue Tian Yun Mao Lei Fang Yan Hu Hong Chen Xiefei Zhu Tianzhen Zhang 2023Molecular Plant2023,16,4:0
15Halogen-Free Flame Retarded Poly(Lactic Acid)with an Isosorbide-Derived Polyphosphonate显示文摘Fabrication of flame retardants from renewable biomass has aroused extensive interest over the past decade.This work reported a synthesis of isosorbide-derived polyphosphonate(PICPP)as an anti-flammable agent for poly(lactic acid)(PLA).The presence of PICPP notably declined the storage modulus of PLA/PICPP owing to the declined molecular weight of PLA catalyzed by the presence of PICPP.PLA and PLA/PICPP thermally degraded in one stage under either air or nitrogen atmosphere.With increasing the amount of PICPP,the onset thermal decomposition temperature of PLA/PICPP was decreased gradually,owing to the earlier decomposition of PICPP.With only 10 wt%of PICPP,PLA/PICPP-10 achieved a high limiting oxygen index of 30.0%and UL-94 V-0 classification,manifesting that PICPP was an efficient anti-flammable agent for PLA.The inclusion of 15 wt%PICPP also caused 33%and 16%decline in PHRR and THR of PLA,respectively.TG-IR results clarified that PLA/PICPP produced the less typical pyrolysis products especially flammable carbonyls than PLA,which may account for the suppressed PHRR and THR values of PLA/PICPP.Wenwen Guo Wei Cai Dong Wang Junling Wang Xiefei Zhu Bin Fei 2022Journal of Renewable Materials2022,10,7:0
