| 1 | Expression patterns and functional divergence of homologous genes accompanied by polyploidization in cotton(Gossypium hirsutum L.)显示文摘Naturally allotetraploid cotton has been widely used as an ideal model to investigate gene expression remodeling as a consequence of polyploidization.However,the global gene pattern variation during early fiber development was unknown.In this study,through RNA-seq technology,we comprehensively investigated the expression patterns of homologous genes between allotetraploid cotton(G.hirsutum)and its diploid progenitors(G.arboreum and G.raimondii)at the fiber early development stage.In tetraploid cotton,genes showed expression level dominance(ELD)bias toward the A genome.This phenomenon was explained by the up-/downregulation of the homologs from the nondominant progenitor(D genome).Gene ontology(GO)enrichment results indicated that the ELD-A genes might be a prominent cause responsible for fiber property change through regulating the fatty acid biosynthesis/metabolism and microtubule procession,and the ELD-D genes might be involved in transcription regulation and stress inducement.In addition,the number and proportion of completely A-and D-subfunctionalized gene were similar at different fiber development stages.However,for neofunctionalization,the number and proportion of reactivated D-derived genes were greater than those of A at 3 and 5 DPA.Eventually,we found that some homologous genes belonging to several specific pathways might create novel asymmetric transcripts between two subgenomes during polyploidization and domestication process,further making the fiber property meet the human demands.Our study identified determinate pathways and their involved genes between allotetraploid cotton and their progenitors at early fiber development stages,providing new insights into the mechanism of cotton fiber evolution. | Zhen Peng Hua Cheng Gaofei Sun Zhaoe Pan Xiao Wang Xiaoli Geng Shoupu He Xiongming Du | 2020 | Science China(Life Sciences)2020，63，10： | 2 |
| 2 | QTL mapping of agronomic and economic traits for four F_(2)populations of upland cotton显示文摘Background:Upland cotton(Gossypium hirsutum)accounts for more than 90%of the annual world cotton output because of its high yield potential.However,yield and fiber quality traits often show negative correlations.We constructed four F_(2)populations of upland cotton,using two normal lines(4133B and SGK9708)with high yield potential but moderate fiber quality and two introgression lines(Suyuan04–3 and J02–247)with superior fiber quality,and used them to investigate the genetic basis underlying complex traits such as yield and fiber quality in upland cotton.We also phenotyped eight agronomic and economic traits and mapped quantitative trait loci(QTLs).Results:Extensive phenotype variations and transgressive segregation were found across the segregation populations.We constructed four genetic maps of 585.97 centiMorgan(cM),752.45 cM,752.45 cM,and 1163.66 cM,one for each of the four F_(2)populations.Fifty QTLs were identified across the four populations(7 for plant height,27 for fiber quality and 16 for yield).The same QTLs were identified in different populations,including qBW4 and qBW2,which were linked to a common simple sequence repeat(SSR)marker,NAU1255.A QTL cluster containing eight QTLs for six different traits was characterized on linkage group 9 of the 4133B×Suyuan04–3 population.Conclusions:These findings will provide insights into the genetic basis of simultaneous improvement of yield and fiber quality in upland cotton breeding. | LI Hongge PAN Zhaoe HE Shoupu JIA Yinhua GENG Xiaoli CHEN Baojun WANG Liru PANG Baoyin DU Xiongming | 2021 | Journal of Cotton Research2021，4，1： | 2 |

| 10 | Genome-wide identification and expression profiling of photosystem II(PsbX)gene family in upland cotton(Gossypium hirsutum L.)显示文摘Background Photosystem II(PSII)constitutes an intricate assembly of protein pigments,featuring extrinsic and intrinsic polypeptides within the photosynthetic membrane.The low-molecular-weight transmembrane protein PsbX has been identified in PSII,which is associated with the oxygen-evolving complex.The expression of PsbX gene protein is regulated by light.PsbX’s central role involves the regulation of PSII,facilitating the binding of quinone molecules to the Qb(PsbA)site,and it additionally plays a crucial role in optimizing the efficiency of photosynthesis.Despite these insights,a comprehensive understanding of the PsbX gene’s functions has remained elusive.Results In this study,we identified ten PsbX genes in Gossypium hirsutum L.The phylogenetic analysis results showed that 40 genes from nine species were classified into one clade.The resulting sequence logos exhibited substantial conservation across the N and C terminals at multiple sites among all Gossypium species.Furthermore,the ortholo-gous/paralogous,Ka/Ks ratio revealed that cotton PsbX genes subjected to positive as well as purifying selection pressure might lead to limited divergence,which resulted in the whole genome and segmental duplication.The expression patterns of GhPsbX genes exhibited variations across specific tissues,as indicated by the analysis.Moreover,the expression of GhPsbX genes could potentially be regulated in response to salt,intense light,and drought stresses.Therefore,GhPsbX genes may play a significant role in the modulation of photosynthesis under adverse abiotic conditions.Conclusion We examined the structure and function of PsbX gene family very first by using comparative genom-ics and systems biology approaches in cotton.It seems that PsbX gene family plays a vital role during the growth and development of cotton under stress conditions.Collectively,the results of this study provide basic information to unveil the molecular and physiological function of PsbX genes of cotton plants. | RAZA Irum PARVEEN Abida AHMAD Adeel HU Daowu PAN Zhaoe ALI Imran DU Xiongming | 2024 | Journal of Cotton Research2024，7，1： | 0 |
| 11 | GhWDL3 is involved in the formation and development of fiber cell morphology in upland cotton(Gossypium hirsutum L.)显示文摘Background Cotton fiber is a model tissue for studying microtubule-associated proteins(MAPs).The Xklp2(TPX2)proteins that belong to the novel MAPs member mainly participate in the formation and development of microtubule(MT).However,there is a lack of studies concerning the systematic characterization of the TPX2 genes family in cotton.Therefore,the identification and portrayal of G.hirsutum TPX2 genes can provide key targets for molecular manipula-tion in the breeding of cotton fiber improvement.Result In this study,TPX2 family genes were classified into two distinct subclasses TPXLs and MAP genes WAVE DAMP-ENED2-LIKE(WDLs)and quite conservative in quantity.GhWDL3 was significantly up-regulated in 15 days post anthe-sis fibers of ZRI-015(an upland cotton with longer and stronger fiber).GhWDL3 promotes all stem hairs to become straight when overexpressed in Arabidopsis,which may indirectly regulate cotton fiber cell morphology during fiber development.Virus induced gene silencing(VIGS)results showed that GhWDL3 inhibited fiber cell elongation at fiber development periods through regulating the expression of cell wall related genes.Conclusion These results reveal that GhWDL3 regulated cotton fiber cell elongation and provide crucial information for the further investigation in the regulatory mechanisms/networks of cotton fiber length. | CHEN Baojun TIAN Zailong FU Guoyong ZHANG Ai SUN Yaru WANG Jingjing PAN Zhaoe LI Hongge HU Daowu XIA Yingying HE Shoupu DU Xiongming | 2024 | Journal of Cotton Research2024，7，1： | 0 |
| 12 | Genomic insight into the divergence and adaptive potential of a forgotten landrace G.hirsutum L.purpurascens显示文摘Wild progenitors are an excellent source for strengthening the genetic basis and accumulation of desirable variation lost because of directional selection and adaptation in modern cultivars.Here,we re-evaluate a landrace of Gossypium hirsutum,formerly known as Gossypium purpurascens.Our study seeks to understand the genomic structure,variation,and breeding potential of this landrace,providing potential insights into the biogeographic history and genomic changes likely associated with domestication.A core set of accessions,including current varieties,obsolete accessions,G.purpurascens,and other geographical landraces,are subjected to genotyping along with multilocation phenotyping.Population fixation statistics suggests a marked differentiation between G.purpurascens and three other groups,emphasizing the divergent genomic behavior of G.purpurascens.Phylogenetic analysis establishes the primitive nature of G.purpurascens,identifying it as a vital source of functional variation,the inclusion of which in the upland cotton(cultivated G.hirsutum)gene pool may broaden the genetic basis of modern cultivars.Genome-wide association results indicate multiple loci associated with domestication regions corresponding to flowering and fiber quality.Moreover,the conserved nature of G.purpurascens can also provide insights into the evolutionary process of G.hirsutum. | Mian Faisal Nazir Shoupu He Haris Ahmed Zareen Sarfraz Yinhua Jia Hongge Li Gaofei Sun Muhammad Shahid Iqbal Zhaoe Pan Xiongming Du | 2021 | Journal of Genetics and Genomics2021，48，6： | 0 |
| 13 | A genome-wide association study of lateral root number for Asian cotton(Gossypium arboreum L.)显示文摘Background:The lateral root is one of the most important organs that constitute the root architecture system in plants.It can directly affect the contact area between plants and soil and plays an important role in plant structural support and nutrient absorption.Optimizing root architecture systems can greatly increase crop yields.This study was designed to identify the molecular markers and candidate genes associated with lateral root development in cotton and to evaluate correlations with yield and disease traits.Result:The number of lateral roots for 14-day old seedlings was recorded for 215 Gossypium arboreum accessions.A correlation analysis showed that the number of lateral roots positively correlates with the sympodial branch node and seed index traits,but negatively correlates with lint percentage.A Genome-wide association study(GWAS)identified 18 significant SNPs with 19 candidate genes associated with the lateral root number.Expression analysis identified three genes(FLA 12,WRKY29,and RBOHA)associated with lateral root development.Conclusion:GWAS an alysis identified key SNPs and candidate gen esfor lateral root number,a nd gen es of FLA 12,WRKY29,and RBOHA may play a pivotal role in lateral root development in Asian cotton. | HU Daowu HE Shoupu SUN Gaofei JIA Yinhua GENG Xiaoli WANG Liru PAN Zhaoe CHEN Baojun LI Hongge ZUBAIR Iqbal WANG Xiaoyang ZHAO Zibo GE Yuting PANG Baoyin DU Xiongming | 2022 | Journal of Cotton Research2022，5，2： | 0 |
| 14 | Type 1 T-cell responses in chlamydial lung infections are associated with local MIP-1a response显示文摘Chemokines and their receptors are important mediators of leukocyte trafficking and recruitment and sometimes work as modulators of T-cell responses during infections and inflammation.Modulating the biological activity of chemokines has been found to influence the course of diseases.However,little is known about the role of chemokine responses during chlamydial lung infections.We therefore analyzed the dynamics of multiple chemokines,which are frequently associated with type 1(Th1)T cell immune responses,and their receptors for their expression in the lungs during Chlamydia muridarum(Cm)infections.We also examined the relationship between chemokine responses and the development of Th1 responses as well as the clearance of infection.Our results showed that in parallel with the high levels of gamma interferon(IFN-c)and IL-12 production in the lungs and draining lymph nodes,and the expansion of IFN-c-producing CD4 and CD81 T cells,the production of the cell-related chemokines RANTES,IFN-c-inducible protein-10(IP-10)and macrophage inflammatory protein-1a(MIP-1a)and their receptor CCR1 was elevated in the lung tissues after infection.Interestingly,in a later phase of infection,the expression of RANTES and IP-10 remained elevated but the expression of MIP-1a and CCR1 decreased to a low level,which suggests a closer association with the pattern of Th1 cytokine responses in the process of infection.These results suggest a close association between the MIP-1a response and the Th1-type T-cell responses in chlamydial lung infections . | Naihong Zhang Zhaoe Wang Xiaofei Tang Haiping Wang Hongzhao Li Huanjun Huang Hong Bai Xi Yang | 2010 | Cellular & Molecular Immunology2010，7，5： | 0 |
| 15 | Genetic diversity and population structure of Gossypium arboreum L. collected in China显示文摘Background: Gossypium arboreum is a diploid species cultivated in the Old World. It possesses favorable characters that are valuable for developing superior cotton cultivars.Method: A set of 197 Gossypium arboreum accessions were genotyped using 80 genome-wide SSR markers to establish patterns of the genetic diversity and population structure. These accessions were collected from three major G. arboreum growing areas in China. A total of 255 alleles across 80 markers were identified in the genetic diversity analysis.Results: Three subgroups were found using the population structure analysis, corresponding to the Yangtze River Valley, North China, and Southwest China zones of G.arboreum growing areas in China. Average genetic distance and Polymorphic information content value of G. arboreum population were 0.34 and 0.47, respectively, indicating high genetic diversity in the G. arboreum germplasm pool. The Phylogenetic analysis results concurred with the subgroups identified by Structure analysis with a few exceptions. Variations among and within three groups were observed to be 13.61% and 86.39%, respectively.Conclusion: The information regarding genetic diversity and population structure from this study is useful for genetic and genomic analysis and systematic utilization of economically important traits in G. arboreum. | JIA Yinhua PAN Zhaoe HE Shoupu GONG Wenfang GENG Xiaoli PANG Baoyin WANG Liru DU Xiongming | 2018 | Journal of Cotton Research2018，1，3： | 0 |
| 16 | Validating field regeneration capacity for selected accessions of Gossypium hirsutum using callus induction and regeneration capacity显示文摘Background Gossypium hirsutum undergoes rapid clonal propagation to regenerate a mature plant through tissue culture.However,the correlation between cotton leaf regeneration,callus induction,and regeneration ability was still obscure.In this research,cotton leaf regeneration level for 21 accessions in the field(new leaves)was observed after the first harvest,and a comparison between field regeneration level and callus induction with its regeneration capacity(new shoots and roots)for the same 21 accessions was carried out.Agronomic traits,including plant height,leaf area,fresh leaf weight,dry leaf weight,the number of flowers and bolls,and biochemical(proline content)and physiological(chlorophyll and carotenoid content)traits during the flowering stage of 21 upland cotton accessions,were investigated.Result A significant correlation between physiological parameters and callus induction was discovered.Callus induction and regeneration capacity of roots and shoots for hypocotyl,cotyledons,and shoot tip tissues were used to validate field leaf regeneration level after the first harvest.CCRI 24 showed significant leaf regeneration in the field and callus induction capacity through callus induction and regeneration.Conclusion We found a substantial relationship between field regeneration capability and callus induction with its regeneration capacity for the hypocotyl,cotyledons,and shoot tip.The results showed that ZS061,Lumian 378,Jimian 863,and ZS065 have the highest moisture retention capacity,while CCRI 24,Liaoyang Duomaomian,and Beizhe Gongshemian have the lowest moisture retention capacity.CCRI 24 has the highest leaf regeneration capacity in the field,while Beizhe Gongshemian has the lowest leaf regeneration capacity.All our result provides a clue for checking the regeneration capacity through leaf regeneration level in the field. | TAJO Sani Muhammad PAN Zhaoe HE Shoupu JIA Yinhua MAHMOOD Tahir NAZIR Mian Fasil HU Daowu WANG Liru SADAU Salisu Bello IBRAHIM Sani AUTA Umar GENG Xiaoli DU Xiongming | 2023 | Journal of Cotton Research2023，6，2： | 0 |
| 17 | Correlation analysis of stem hardness traits with fiber and yield-related traits in core collections of Gossypium hirsutum显示文摘Background:Stem hardness is one of the major influencing factors for plant architecture in upland cotton(Gossypium hirsutum L.).Evaluating hardness phenotypic traits is very important for the selection of elite lines for resistance to lodging in Gossypium hirsutum L.Cotton breeders are interested in using diverse genotypes to enhance fiber quality and high-yield.Few pieces of research for hardness and its relationship with fiber quality and yield were found.This study was designed to find the relationship of stem hardness traits with fiber quality and yield contributing traits of upland cotton.Results:Experiments were carried out to measure the bending,acupuncture,and compression properties of the stem from a collection of upland cotton genotypes,comprising 237 accessions.The results showed that the genotypic difference in stem hardness was highly significant among the genotypes,and the stem hardness traits(BL,BU,AL,AU,CL,and CU)have a positive association with fiber quality traits and yield-related traits.Statistical analyses of the results showed that in descriptive statistics result bending(BL,BU)has a maximum coefficient of variance,but fiber length and fiber strength have less coefficient of variance among the genotypes.Principal component analysis(PCA)trimmed quantitative characters into nine principal components.The first nine principal components(PC)with Eigenvalues>1 explained 86%of the variation among 237 accessions of cotton.Both 2017 and 2018,PCA results indicated that BL,BU,FL,FE,and LI contributed to their variability in PC1,and BU,AU,CU,FD,LP,and FWPB have shown their variability in PC2.Conclusion:We describe here the systematic study of the mechanism involved in the regulation of enhancing fiber quality and yield by stem bending strength,acupuncture,and compression properties of G.hirsutum. | RAZA Irum HU Daowu AHMAD Adeel LI Hongge HE Shoupu NAZIR Mian Faisal WANG Xiaoyang JIA Yinhua PAN Zhaoe ZHANG Peng YASIR Muhammad IQBAL Muhammad Shahid GENG Xiaoli WANG Liru PANG Baoyin DU Xiongming | 2021 | Journal of Cotton Research2021，4，1： | 0 |
