Phylogenetic tree of SWEETs from daylily and other plants. The protein sequences of the 96 SWEETs from daylily, rice, Zea mays, Arabidopsis, and Vitis vinifera were aligned by Clustal Omega, and the phylogenetic tree was constructed by MEGA7.0 using the neighbor-joining method with 1000 bootstrap replicates. SWEETs of daylily, rice, Zea mays, Arabidopsis, and Vitis vinifera were prefixed with Hf, Os, Zm, At, and Vv, respectively
