Fig. 1From: Identification and characterization analysis of sulfotransferases (SOTs) gene family in cotton (Gossypium) and its involvement in fiber developmentChromosome distribution of SOT genes of four cotton species. The cotton species name was on the left of graphic and chromosome name was at the top of each bar. The vertical scale on the left showed the size of chromosomes and black lines indicated the corresponding position of genes. The scale of the chromosomes was millions of base pairs (Mb). The gene names was correspond to those in Additional file 1: Table S1Back to article page
