From: The sorghum SWEET gene family: stem sucrose accumulation as revealed through transcriptome profiling
Evolutionary tree of SWEET. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. This analysis involved 63 amino acid sequences (23 of Sorghum bicolor, 17 of Arabidopsis thaliana, 23 of Oryza sativa). Sorghum SWEET genes focused in this study are underlined by red and functionally validated Arabidopsis or rice SWEET genes are underlined by blue
