From: Genome-wide identification and expression analysis of DREB family genes in cotton
Number of DREB genes from four cotton species and a phylogenetic tree of DREB proteins among Gossypium spp. and Arabidopsis thaliana. A The number of DREB genes in G. barbadense, G. hirsutum, G. arboreum, and G. raimondii, among which, Chr and Scaff indicated respectively the chromosome and scaffold. B The unrooted phylogenetic tree was structured with the maximum likelihood method (1000 bootstraps) based on the amino acid sequence of DREB proteins
