Phylogenetic analysis of cotton SRO genes. The maximum likelihood phylogenetic tree among SRO genes of G. arboreum, G. raimondii,G. barbadense, G. hirsutum, Arabidopsis, maize, potato, and apple. The tree was constructed using MEGA 7.0 (1Â 000 bootstrap value) using the full length amino acids sequences of SRO genes. Three groups were represented with different color
