Phylogenetic analysis of Gossypium hirsutum LRR-RLK protein sequences. The evolutionary history was inferred using the Neighbor-Joining method with 1000 bootstrap replication. The evolutionary distances were computed using the p-distance method and are in the units of the number of amino acid substitutions per site. The analysis involved 543 G. hirsutum LRR-RLK protein sequences and 234 Arabidopsis thaliana LRR-RLK protein sequences. All positions containing gaps and missing data were eliminated. Evolutionary analyses were conducted in MEGA6
