Expansion/reduction in Arabidopsis and tomato RLK subfamilies and functional inference. The membership size of RLK subfamilies in Arabidopsis (At) and tomato (Sl) is indicated . Values in bold and with asterisks indicate statistical significance by the test of equal or given proportions (α=0.05). Subfamilies with significantly large proportion of duplication (dup.) or deletion (del.) were considered to have specifically expanded or reduced respectively after the divergence of Arabidopsis and tomato species. Subfamilies that presented statistically large proportion of RLKs organized in tandem repeats (t.r.) and/or of RLKs functionally annotated in defense response (def.) category were considered to be defense-related (red arrows). Conversely, subfamilies with significantly large proportion of members annotated in developmental process (dev.) category were classified as development-related (blue arrows). Green arrow indicates the LRRII subfamily that presented large proportion in both functional categories. Legend: dup.: duplication events; del.: deletion events.
