a Phylogenetic tree of LHC genes in G. hirsutum, G. arboreum, G. raimondii, Arabidopsis thaliana and Theobroma cacao. The tree was done using MEGA 7.0. b Synteny blocks formation among cotton species chromosomes. A: Chromosomes of G. arboreum; D: Chromosomes of G. raimondii, At and Dt: Chromosomes of A and D Subgenome of the tetraploid cotton, G. hirsutum
