Fig. 3From: Evolution, expression and functional analysis of cultivated allotetraploid cotton DIR genesEvolutionary history of cotton DIR gene family. a Phylogenetic relationships of DIR genes from V. vinifera, G. max, A. thaliana, T. cacao, G. arboreum, G. raimondii, G. barbadense and G. hirsutum. b DIR genes were assigned to distinct clades. The figures in circles stand for the number of genes. c The collinearity among multiple Gossypium genomes. Lines between chromosomes show orthologous genesBack to article page
