Legume species are an important plant model because of their protein-rich physiology. The adaptability and productivity legumes limited by major biotic abiotic stresses. Responses to these stresses directly involve plasma membrane receptor proteins known as receptor-like kinases proteins. Evaluating the homology relations among RLK RLP for seven legume species, exploring presence synteny blocks allow increased understanding evolutionary relations, physical position, chromosomal distribution in related shared roles stress responses.Typically, a high proportion belong orthologous clusters, which is confirmed this study, where between 66 90% RLKs RLPs per were classified clusters. One-third evaluated syntenic had RLK/RLP genes both non-legumes. Among legumes, 75 98% present blocks. segments Phaseolus vulgaris Vigna unguiculata, two that diverged ~ 8 mya, highly similar. experimentally validated resistance identified resistant FLS2, BIR2, ERECTA, IOS1, AtSERK1 from Arabidopsis SLSERK1 Solanum lycopersicum different pairwise species. Meanwhile, only LYM1- gene with Glycine max.The orthology analysis suggests dynamic evolution family, 85% 83 88% belonging clusters evaluated. In fact, 10-species comparison, lower number singleton reported compared RLK, suggesting positions more physically conserved RLK. identification revealed multiple on chromosomes. Additionally, P. appropriate anchor comparative genomics legumes.
