Fig. 2. Phylogenetic tree derived from the amino-acid sequences of 25 MdSWEET genes in apple and 17 AtSWEET genes in Arabidopsis.

Fig. 2

All the SWEET genes are divided into four clades (I–IV), and numbers near branches represent bootstrap values. The circles and triangles indicate SWEETs from Arabidopsis and apple, respectively
