Expression pattern of ten fiber-related genes related to cotton fiber quality. a Expression pattern of ten genes related to fiber quality in distinct tissues. b Expression level of these genes in domesticated cotton (TM-1) and two wild relatives (TX665, G. hirsutum var. palmeri; TX2094, G. hirsutum var. yucatanense). Fisher’s exact test, * P value <0.05 and fold change >2. c Identification of 109 selective sweeps through comparisons of races and cultivars in G. hirsutum. The values of π race/π cultivar were plotted against the position on each of the 26 chromosomes. The horizontal line indicates the genome-wide threshold of selection signals (π race/π cultivar >25). Asterisks indicate the strongest selection signal locus in D11 and the longest selective sweep in A06. Lines linking b and c indicate the gene locus in selection sweeps. The fiber quality-related QTLs around these gene loci are shown beside these lines
