Phylogenetic analysis of PERK proteins from 16 Brassicaceae species. 418 PERK proteins are grouped into four subfamilies. The gene number of 16 Brassicaceae species in different groups was calculated in Table S2. Percent bootstrap values (1000 iterations) are indicated in every branch. The different-colored arcs indicate different groups of PERKs. The maximum likelihood (ML) tree was constructed by MEGA7 with the Bootstrap method (1000 replications) and the Jones, Taylor, and Thornton amino acid substitution (JTT) model
