Extended Data Fig. 4: Distance histogram calculated on domain sequences with matching family annotations.

a, For TKPs with two domains from the RLK–Pelle Lec family. b, For TKPs with two domains from RLK–Pelle DLSV family. Pairwise distances were calculated for sequences from two subfamilies by dist.alignment function from seqinr (version 4.2-16) R package.
