Fig. 1From: The PIN gene family in cotton (Gossypium hirsutum): genome-wide identification and gene expression analyses during root development and abiotic stress responsesPhylogenetic analysis of PIN family genes from G. hirsutum, G. arboreum, G. raimondii and A. thaliana. The phylogenetic tree was constructed using MEGA 5.0 with the neighbor-joining method. The origin of the PIN genes are indicated by colored circles as follows: G. hirsutum (red), G. arboretum (yellow), G. raimondii (green), and A. thaliana (black). Numbers on branches are bootstrap values calculated from 1000 replicatesBack to article page
