RNA interference (RNAi), is a powerful new technology in the discovery of genetic sequence functions, and has become a valuable tool for functional genomics of cotton (Gossypium sp.). The rapid adoption of RNAi has replaced previous antisense technology. RNAi has aided in the discovery of function and biological roles of many key cotton genes involved in fiber development, fertility and somatic...

A detailed restriction fragment length polymorphism map was used to determine the chromosomal locations and subgenomic distributions of quantitative trait loci (QTLs) segregating in a cross between cultivars of allotetraploid (AADD) Gossypium hirsutum (‘‘Upland’’ cotton) and Gossypium barbadense (‘‘Sea Island,’’ ‘‘Pima,’’ or ‘‘Egyptian’’ cotton) that differ markedly in the quality and quantity ...

Cotton (Gossypium hirsutum) is the most important non-food plant in the world. Studies concerning the fiber quality and plant fitness of cotton at molecular level depend on high sensitive and reproducible gene-expression assays. However, only a few reports have described genes suitable for normalizing gene expression data. In this study, we report for the first time that microRNAs (miRNAs) are ...

Limited polymorphism and narrow genetic base, due to genetic bottleneck through historic domestication, highlight a need for comprehensive characterization and utilization of existing genetic diversity in cotton germplasm collections. In this study, 288 worldwide Gossypium barbadense L. cotton germplasm accessions were evaluated in two diverse environments (Uzbekistan and USA). These accessions...

are tandem repetitive DNA sequences. The availability and abundance of SSR markers throughout the cotton Knowledge of genetic diversity and relationships among breeding genome, their polymorphic nature, codominance, and materials has a significant impact on crop improvement. Association between parental divergence and progeny performance has not been polymerase chain reaction (PCR)-based assay ...
