RLK — Capsicum annuum

Summary

CaRLK (T459_23849) on pepper chromosome 9 encodes a protein kinase domain-containing protein with transmembrane receptor serine/threonine kinase activity, coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity, belonging to the L-type lectin receptor kinase family. This gene is associated with pollen aperture formation and localisation, cellular responses to ethylene and cytokinin signaling, salinity response and its inhibition, upregulation of innate immune response, regulation of defence response to fungi, defense response to oomycetes, immune response, response to salicylate, somatic embryogenesis, seed germination, cell differentiation, regulation of developmental growth and growth, transposition, and virus-induced PTGS. It is linked to ethylene sensitivity, defense response against herbivory, and methyl jasmonate-mediated stomatal closure. Studies of related genes in other species connect the family to drought tolerance, salt response, fruit size, root traits, self-incompatibility, and resistance to Fusarium and Pseudomonas.
