Figure 1. Phylogenetic tree of SnRK genes from H. coronarium, Arabidopsis, and rice.

Sixty HcSnRK genes, 39 AtSnRK genes, and 48 OsSnRK genes are clustered as SnRK1, SnRK2, and SnRK3 subgroups. The detailed information of these genes from different plants are provided in Table S4. Clustal X software was used for multiple sequence alignment and MEGA 7 software used to construct a phylogenetic tree by the neighbor-joining method.
