Fig. 1From: Genome-wide identification and expression profiling of photosystem II (PsbX) gene family in upland cotton (Gossypium hirsutum L)Phylogenetic tree relationships between 10 G. hirsutum, 10 G. barbadence, 5 G. arboreum, 5 G. raimondii, 1 Arabidopsis, 2 O. stiva, 3 P. trichocarpa, 2Â T. cacao, 2 genes from Vitis Vinefera. The MEGA X program using the NJ (Neighbor-joining) method created the phylogenetic tree. The bootstrap test was done with 1Â 000 iterations. The different species genes are shown in different colorsBack to article page
