Phylogenetic topology of plant LYK proteins. A majority-ruled parsimony tree with maximum-likelihood branch lengths was calculated using full-length LYK sequences. Bootstrap values of 1000 independent trees larger than 70 were labeled on each branch. The tree was rooted using two algae sequences, Vc_chitinase (AAC13727) and CrLMR2 (EDP05962). Major clades are separated by solid horizontal lines and subclades are separated by dashed lines. On the right, the numbers of the LysM motifs are aligned in the first column, followed by the numbers of exons in the middle column, and tandemly arrayed genes are labeled in the third column.
