Additional file 3: of Genome-wide identification, phylogeny, evolution, and expression patterns of MtN3/saliva/SWEET genes and functional analysis of BcNS in Brassica rapa

Figure S1. Copy number changes in the B. rapa and Arabidopsis MtN3/saliva/SWEET genes in Clades A–D. The numbers in ellipses and rectangles represent the numbers of MtN3/saliva/SWEET genes in the extant and ancestral species, respectively. The numbers on the branches with plus and minus symbols represent the numbers of gene gains and losses, respectively. (TIFF 953 kb)
