Synteny analysis of GRF genes between G. hirsutum and the other three Gossypium spp. species. Gray lines in the background indicate the collinear blocks within G. hirsutum and other three cotton genomes, while the red lines highlight the syntenic GRF gene pairs. The specie names with the prefixes ‘A1’, ‘At’, ‘A2’, ‘Dt’, and ‘D5’ represent G. herbaceum, A subgenomes of G. hirsutum, G. arboreum, D subgenomes of G. hirsutum and G. raimondii, respectively
