Expression patterns of GhCPK genes in 14 representative tissues from G. hirsutum. The heat map, generated with Genesis, shows the hierarchical clustering of GhCPK genes into four groups in vegetative organs (root, stem, and leaf), in floral organs (petal, pistil, and stamen), and at different developmental stages of ovule and fiber tissues. The reads per kilobase of transcript per million mapped reads (RPKM) values were log10 transformed and indicated the expression level of GhCPK genes, while the gradient color (red/black/green) reflects the expression levels (high to low)
