Phylogenetic analysis of AITRs and AITRLs, and amino acid alignment of AITRL, GmAITRL1, SlAITRL and AITR5. (a) Phylogenetic analysis of AITRs and AITRLs. AITRs and AITRLs in the plant species selected were identified on phytozome v12 (https://phytozome.jgi.doe.gov/pz/portal.html#), and their full-length amino acid sequences were used for phylogenetic analysis by using “One Click” mode on phylogeny (http://www.phylogeny.fr/simple_phylogeny.cgi) with default settings. Branch support values are indicated above the branches. (b) Amino acid alignment of AITRL, GmAITRL1, SlAITRL and AITR5. Full-length amino acid sequences of AITRL, GmAITRL1, SlAITRL and AITR5 were obtained on phytozome and used for sequence alignment by using BioEdit 7.0 (https://bioedit.software.informer.com/7.0/). The identical amino acids in AITRL, GmAITRL1, SlAITRL and AITR5 were shaded in black, and the similar ones in gray. Underline indicates the partial conserved LxLxL motif in AITR5.
