From: A genome-wide analysis of SWEET gene family in cotton and their expressions under different stresses
Phylogenetic relationships, gene structure and domains compositions of GaSWEETs. a Phylogenetic relationship of SWEET proteins from A. thaliana and G. arboreum. The phylogenetic tree was constructed using MEGA 6.0 with the NJ method with 1 000 bootstrap replicates. The I clade, II clade, III clade, and IV clade is marked in cyan, purple, blue and pink, respectively. b Exon/intron structures of GaSWEETs. The introns and CDS are represented by orange boxes and black lines, respectively. c Protein domains. Each domain is represented in the colored box
