Fusarium wilt (FW) disease of cotton, caused by the fungus oxysporum f. sp. vasinfectum (Fov), causes severe losses in cotton production worldwide. Though significant advancements have been made development FW-resistant Upland (Gossypium hirsutum) resistance screening programs, precise genes and corresponding molecular mechanisms for to Fov remain unclear. Herein it is reported that Fov7, a gen...

The unpredictability of cotton yields is a great concern to the cotton industry. High temperatures are considered to be one of the main environmental factors contributing to variable yields in cotton (Gossypium hirsutum L.). This has been attributed to a negative effect on respiration and carbohydrate accumulation, but the evidence for this is lacking. In this study it was hypothesized that hig...

The Sea Island cotton (Gossypium barbadense L.) has been highly valued in verticillium wilt resistance and many fiber qualities including fiber length, strength and fineness. To identify whether it had some special genes in fiber development in comparison with the Upland cotton (G. hirsutum L.), an actin-depolymerizing factor (ADF) gene was cloned and characterized in this research. A 420 bp op...

Abstract Background Upland cotton ( Gossypium hirsutum ) accounts for more than 90% of the annual world output because its high yield potential. However, and fiber quality traits often show negative correlations. We constructed four F 2 populations upland cotton, using two normal lines (4133B SGK9708) with potential but moderate introgression (Suyuan04–3 J02–247) superior quality, used them to ...

Abstract Background High temperature stress at peak flowering stage of cotton is a major hindrance for crop potential. This study aimed to increase genetic divergence regarding heat tolerance in newly developed cultivars and hybrids. Fifty genotypes 40 F 1 (hybrids) were tested under field conditions following the treatments, viz., high control August October April June sowing, respectively. Re...
