Receptor-like proteins (RLPs) belong a large multigene family of cell surface receptors, and it is known to be involved in plant development and defense. Although RLP family has been studied in many plants, there has been no reports on identification and characterization of RLPs in pepper. In this study, we identified and analyzed pepper RLPs using pepper genome and transcriptome. A total of 153 RLP genes were identified in the pepper genome. Phylogenetic comparison with Arabidopsis RLPs revealed that pepper and Arabidopsis RLP families evolved independently. Pepper RLPs clustered into eleven clades including characterized RLPs such as Cf-9, Ve2, CLV2, and TMM. Four and two out of eleven clades contained RLPs known to be involved in plant defense and development, respectively. Furthermore, transcriptome of RLP genes showed dynamics of global gene expression changes either during plant growth stages and pepper-pathogen interactions. We expected that the results in this study will be useful for cloning of genes and provide clue for functional analysis of RLPs in pepper.
