Identification and classification of SUS genes in 16 angiosperm species. The phylogenetic tree was constructed according to the AGP IV system [22]. Polyploidization events described in previous studies [2326] are mapped onto the tree (blue ovals and orange diamonds). The total number of SUS genes and its classification in each plant are shown. WGD: Whole-genome duplication; WGT: Whole-genome triplication; MYA: Million years ago
