Fig. 2From: Soybean (Glycine max) SWEET gene family: insights through comparative genomics, transcriptome profiling and whole genome re-sequence analysisPhylogenetic relationship of SWEET gene family proteins in 13 different species. The phylogenetic tree was built using the neighbor-joining (NJ) method implemented in MEGA5.1. The roman numerals (I – IV) indicated with different colors, represents the clades associated with higher and lower plant groups. The numbers at the nodes represent bootstrap percentage values based on 1000 replications. Genes from each species are marked with different bullet point colorsBack to article page
