RLK and LRR domain functions have distinct evolutionary trajectories. a) Time-calibrated chronogram of 6 A. thaliana LRR-RLK genes showing approximate divergence times between paralogs. b) Illustrations of representative Arabidopsis siliques from mutants transformed with (chimeric) transgenes. c) Percentage of flowers from clv1 or hae/hsl2 mutants complemented by various paralogous domains. Numbers in bars indicate independent events (5 to 10 flowers per event). Letters indicate significantly different groups (analysis of variance, Tukey's post hoc). H3*, catalytically dead HSL3 variant.
