Relationship between phylogeny and gene coexpression patterns. (A) Coexpression analysis for subfamilies LRR_8B, LRR_3, and LRCK_9. Phylogenetic information was incorporated by reordering the rows according to the topology in the phylogenetic tree (left) or disregarded (right). Green color indicates high coexpression values, and red color indicates dissimilarity in expression context. Square patches of similar color denote agreements between the clustering of columns and rows. (B) Phylogenetic relationship and duplication annotation correspond for members of the LRR_8B, LRR_3, and LRCK_9 subfamily. Genes are connected by curves if they are identified as duplicated pairs by proximal duplication (green), segmental duplications (red) and transpositions (orange). In the case of transposition events, the ancestral gene is indicated by a vertical line.
