Phylogenetic analysis and classification of peanut and A. thaliana LRR-RLK proteins. The phylogenetic tree was established with full sequences using the maximum-likelihood method with 1000 bootstrap replications and the evolutionary distances were computed using the p-distance method. Red sequences indicate the AtLRR-RLKs. Each RLK clade is depicted by a different colour, representing the 24 clades that were identified. Labelled lines on the outside of the tree represent clade names as defined in the text
