Expression profiling of GhIQD genes during four developmental stages of the cotton fiber cell. a A hierarchical clustering heatmap of GhIQD gene expression in fiber cells at 5, 10, 20, and 25 DPA. These data were obtained from the transcriptome data available on the Cottongen website (https://www.cottongen.org/). The color scale represents the expression values, which have been normalized by the online software Omicshare b Gene expression of 89 GhIQD genes in six different clusters during four developmental stages of cotton fiber cells
