Fig. 7: Cf-2 evolved in a tomato-specific subclade of the Hcr2 gene family.
From: Evolution of a guarded decoy protease and its receptor in solanaceous plants
a Phylogenetic tree of the Hcr2 gene family based on the conserved N-terminal and C-terminal regions (corresponding to residues 1-138 and 713-1112 of Cf-2). Approximately Maximum Likelihood tree was generated using FastTreeMP, based on the LG model69. The bootstrap consensus tree inferred from 1000 replicates is taken to represent the evolutionary history of the taxa analysed. Shown are percentage bootstrap values. Hcr2 family members with known recognition specificity are indicated in bold, the chromosome on which these genes reside is indicated, expected chromosome numbers are indicated in parentheses. Scale bar, amino acid substitutions per site. b Amino acid alignment comparison to Cf-2 using MUSCLE. LRRs of domain C were predicted using LRRfinder70. Numbers indicate total number of LRRs in domain C. Shown are LRR region evolving by intragenic recombination (gray); Cf-2 (red) and Cf-5 (blue); unknown sequences (dotted lines). A, signal peptide; B, N-terminal LRR flanking domain; C, LRR region; D, juxtamembrane region; E, transmembrane domain; F, cytoplasmic tail.
