| 1 | Comprehensive analysis of NAC transcription factors in diploid Gossypium: sequence conservation and expression analysis uncover their roles during fiber development显示文摘Determining how function evolves following gene duplication is necessary for understanding gene expansion.Transcription factors(TFs)are a class of proteins that regulate gene expression by binding to specific cis-acting elements in the promoters of target genes,subsequently activating or repressing their transcription.In the present study,we systematically examined the functional diversification of the NAC transcription factor(NAC-TFs)family by analyzing their chromosomal location,structure,phylogeny,and expression pattern in Gossypium raimondii(Gr)and G.arboreum(Ga).The 145 and 141 NAC genes identified in the Gr and Ga genomes,respectively,were annotated and divided into 18 subfamilies,which showed distinct divergence in gene structure and expression patterns during fiber development.In addition,when the functional parameters were examined,clear divergence was observed within tandem clusters,which suggested that subfunctionalization had occurred among duplicate genes.The expression patterns of homologous gene pairs also changed,suggestive of the diversification of gene function during the evolution of diploid cotton.These findings provide insights into the mechanisms underlying the functional differentiation of duplicated NAC-TFs genes in two diploid cotton species. | Haihong Shang Zhongna Wang Changsong Zou Zhen Zhang Weijie Li Junwen Li Yuzhen Shi Wankui Gong Tingting Chen Aiying Liu Juwu Gong Qun Ge Youlu Yuan | 2016 | Science China(Life Sciences)2016，59，2： | 12 |
| 2 | Constructing a high-density linkage map for Gossypium hirsutum × Gossypium barbadense and identifying QTLs for lint percentage显示文摘To introgress the good fiber quality and yield from Gossypium barbadense into a commercial Upland cotton variety, a high-density simple sequence repeat(SSR) genetic linkage map was developed from a BC1F1 population of Gossypium hirsutum×Gossypium barbadense. The map comprised 2,292 loci and covered 5115.16 centi Morgan(c M) of the cotton AD genome, with an average marker interval of 2.23 c M. Of the marker order for 1,577 common loci on this new map, 90.36% agrees well with the marker order on the D genome sequence genetic map. Compared with five published high-density SSR genetic maps, 53.14% of marker loci were newly discovered in this map. Twenty-six quantitative trait loci(QTLs) for lint percentage(LP) were identified on nine chromosomes. Nine stable or common QTLs could be used for marker-assisted selection. Fifty percent of the QTLs were from G. barbadense and increased LP by 1.07%–2.41%. These results indicated that the map could be used for screening chromosome substitution segments from G. barbadense in the Upland cotton background, identifying QTLs or genes from G. barbadense, and further developing the gene pyramiding effect for improving fiber yield and quality. | Yuzhen Shi Wentan Li Aiguo Li Ruihua Ge Baocai Zhang Junzhi Li Guangping Liu Junwen Li Aiying Liu Haihong Shang Juwu Gong Wankui Gong Zemao Yang Feiyü Tang Zhi Liu Weiping Zhu Jianxiong Jiang Xiaonan Yu Tao Wang Wei Wang Tingting Chen Kunbo Wang Zhengsheng Zhang Youlu Yuan | 2015 | Journal of Integrative Plant Biology2015，57，5： | 7 |
| 3 | QTL mapping for fiber quality and yieldrelated traits across multiple generations in segregating population of CCRI 70显示文摘Background:Cotton is a significant economic crop that plays an indispensable role in many domains.Gossypium hirsutum L.is the most important fiber crop worldwide and contributes to more than 95%of global cotto n production.Identifying stable quantitative trait locus(QTLs)controlling fiber quality and yield related traits are necessary prerequisites for marker-assisted selection(MAS).Results:A genetic linkage map was constructed with 312 simple sequence repeat(SSR)loci and 35 linkage groups using JoinMap 4.0;the map spanned 1 929.9 cM,with an average interval between two markers of 6.19 cM,and covered approximately 43.37%of the cotton genome.A total of 74 QTLs controlling fiber quality and 41 QTLs controlling yield-related traits were identified in 4 segregating generations.These QTLs were distributed across 20 chromosomes and collectively explained 1.01%?27.80%of the observed phenotypic variations.In particular,35 stable QTLs could be identified in multiple generations,25 common QTLs were con sistent with those in previous studies,and 15 QTL clusters were found in 11 chromosome segments.Conclusion:These studies provide a theoretical basis for improving cotton yield and fiber quality for molecular marker-assisted selection. | DENG Xiaoying GONG Juwu LIU Aiying SHI Yuzhen GONG Wankui GE Qun LI Junwen SHANG Haihong WU Yuxiang YUAN Youlu | 2019 | Journal of Cotton Research2019，2，2： | 3 |
| 4 | QTL mapping for plant height and fruit branch number based on RIL population of upland cotton显示文摘Background:Plant height(PH)and fruit branch number(FBN)are important traits for improving yield and mechanical harvesting of cotton.In order to identify genes of PH and FBN in cotton germplasms to develop superior cultivars,quantitative trait loci(QTLs)for these traits were detected based on the phenotypic evaluation data in nine environments across four locations and 4 years and a previously reported genetic linkage map of an recombinant inbred line(RIL)population of upland cotton.Results:In total,53 QTLs of PH and FBN,were identified on 21 chromosomes of the cotton genome except chromosomes c02,c09-c11,and c22.For PH,27 QTLs explaining 3.81%–8.54%proportions of phenotypic variance were identified on 18 chromosomes except c02,c08-c12,c15,and c22.For FBN,26 QTLs explaining 3.23%–11.00%proportions of phenotypic variance were identified on 16 chromosomes except c02-c03,c06,c09-c11,c17,c22-c23,and c25.Eight QTLs were simultaneously identified in at least two environments.Three QTL clusters containing seven QTLs were identified on three chromosomes(c01,c18 and c21).Eleven QTLs were the same as previously reported ones,while the rest were newly identified.Conclusions:The QTLs and QTL clusters identified in the current study will be helpful to further understand the genetic mechanism of PH and FBN development of cotton and will enhance the development of excellent cultivars for mechanical managements in cotton production. | LIU Ruixian XIAO Xianghui GONG Juwu LI Junwen ZHANG Zhen LIU Aiying LU Quanwei SHANG Haihong SHI Yuzhen GE Qun IQBAL Muhammad Sajid CHEN Quanjia YUAN Youlu GONG Wankui | 2020 | Journal of Cotton Research2020，3，1： | 1 |
| 5 | Evolution of pectin synthesis relevant galacturonosyltransferase gene family and its expression during cotton fiber development显示文摘Background:Pectin is a key substance involved in cell wall development,and the galacturonosyltransferases(GAUTs)gene family is a critical participant in the pectin synthesis pathway.Systematic and comprehensive research on GAUTs has not been performed in cotton.Analysis of the evolution and expression patterns of the GAUT gene family in different cotton species is needed to in crease kno wledge of the functi on of pectin in cotto n fiber development.Results:In this study,we have identified 131 GAUT genes in the genomes of four Gossypium species(G.raimondii,G barbadense,G.hirsutum,and G.arboreum),and classified them as GAUT-A,GAUT-B and GAUT-C,which coding probable galacturonosyltransferases.Among them,the GAUT genes encode proteins GAUT1 to GAUT15.All GAUT proteins except for GAUT7 contai n a con served glycosyl transferase family 8 domain(H-DN-A-SW-S-V-H-T-F).The conserved sequence of GAUT7 is PLN(phospholamban)02769 domain.According to c/s-elemet analysis,GAUT genes transcript levels may be regulated by horm ones such as JA,GA,SA,ABA,Me-JA,and IA A.The evoluti on and transcription patterns of the GAUT gene family in different cotton species and the transcript levels in upland cotton lines with different fiber st「ength were analyzed.Peak transcript level of GhGAUT genes have been observed before 15 DPA.In the six materials with high fiber strength,the transcription of GhGAUT genes were concentrated from 10 to 15 DPA;while the highest transcript levels in low fiber st「ength materials were detected between 5 and 10 DPA.These results lays the foundation for future research on gene function during cotton fiber development.Conclusions:The GAUT gene family may affect cotton fiber development,including fiber elongation and fiber thickening.In the low strength fiber lines,GAUTs mainly participate in fiber elongation,whereas their major effect on cotton with high strength fiber is related to both elongation and thickening. | FAN Senmiao LIU Aiying ZOU Xianyan ZHANG Zhen GE Qun GONG Wankui LI Junwen GONG Juwu SHI Yuzhen DENG Xiaoying JIA Tingting YUAN Youlu SHANG Haihong | 2021 | Journal of Cotton Research2021，4，3： | 0 |
| 6 | Current advances in pathogen-plant interaction between Verticillium dahliaeand cotton provide new insight in the disease management显示文摘Verticillium wilt is the second serious vascular wilt caused by the phytopathogenic fungus Verticillium dahliae Kleb.It has distributed worldwide,causing serious yield losses and fiber quality reduction in cotton production.The pathogen has developed different mechanisms like the production of cell wall degrading enzymes,activation of virulence genes and protein effectors to succeed in its in fection.Cott on plant has also evolved multiple mechanisms in response to the fungus infection,including a strong production of lignin and callose deposition to strengthen the cell wall,burst of reactive oxygen species,accumulation of defene hormones,expression of defense-related genes,and target-directed strategies like cross-kingdom RNAi for specific virulent gene silencing.This review summarizes the recent progress made over the past two decades in understanding the interactions between cotton plant and the pathogen Verticillium dahliae during the infection process.The review also discusses the achievements in the control practices of cotton verticillium wilt in recent years,including cultivation practices,biological control,and molecular breeding strategies.These studies reveal that effective management strategies are needed to control the disease,while cultural practices and biological control approaches show promising results in the future.Furthermore,the biological control approaches developed in recent years,including antagonistic fungi,endophytic bacteria,and host induced gene sile ncing strategies provide efficie nt choices for in teg rated disease management. | PALANGA Koffi Kibalou LIU Ruixian GE Qun GONG Juwu LI Junwen LU Quanwei LI Pengtao YUAN Youlu GONG Wankui | 2021 | Journal of Cotton Research2021，4，3： | 0 |
| 7 | Genome-wide identification,characterization,and expression analysis of aluminum-activated malate transporter genes(ALMTs)in Gossypium hirsutum L.显示文摘Aluminum-activated malate transporters(ALMT)are widely involved in plant growth and metabolic processes,including adaptation to acid soils,guard cell regulation,anion homeostasis,and seed development.Although ALMT genes have been identified in Arabidopsis,wheat,barley,and Lotus japonicus,little is known about its presence in Gossypium hirsutum L.In this study,ALMT gene recognition in diploid and tetraploid cotton were done using bioinformatics analysis that examined correlation between homology and evolution.Differentially regulated ALMT genetic profile in G.hirsutum was examined,using RNA sequencing and qRT-PCR,during six fiber developmental time-points,namely 5 d,7 d,10 d,15 d,20 d,and 25 d.We detected 36 ALMT genes in G.hirsutum,which were subsequently annotated and divided into seven sub-categories.Among these ALMT genes,34 had uneven distribution across 14/26 chromosomes.Conserved domains and gene structure analysis indicated that ALMT genes were highly conserved and composed of exons and introns.The GhALMT gene expression profile at different DPA(days post anthesis)in different varieties of G.hirsutum is indicative of a crucial role of ALMT genes in fiber development in G.hirsutum.This study provides basis for advancements in the cloning and functional enhancements of ALMT genes in enhancing fiber development and augmenting high quality crop production. | QUANWEI LU YUZHEN SHI RUILI CHEN XIANGHUI XIAO PENGTAO LI JUWU GONG RENHAI PENG YOULU YUAN | 2022 | BIOCELL2022，46，5： | 0 |
