Cladogram of ERECTA family genes (ERfs) among 49 plant species. The cladogram was constructed using protein sequences of all identified ERfs. One LRR protein Cre17.g741150.t2.1 (Cre-OG) from Chlamydomonas reinhardtii was picked as an outgroup. Two major clades, ERECTA (ER) clade and ER-LIKE (ERL) clade were identified based on their relationship to Arabidopsis ER and ERL proteins. (A) Simplified cladogram of ER and ERL proteins across major divisions (e.g., kingdoms or sub-kingdoms). Each clade and group are indicated by different colors; (B) Cladogram of all ER proteins across 49 plant species; (C) Cladogram of all ERL proteins across 49 plant species. Major divisions are shown on the right side with the same color schemes as used in (A); two whole-genome duplication (WGD) events specific to grasses and legumes are indicated by blue stars; the rice ER and ERL proteins were highlighted are underlined. The abbreviations for each species were given in Table 1. A full phylogenetic tree with bootstrap values was given in Supplementary Figure S1. Abbreviation: Gymno., Gymnosperms; Basal Angio., Basal Angiosperms.
