RLK — Cicer arietinum

Summary

LOC101491489 (CaRLK) on chickpea chromosome 7 encodes a protein with leucine-rich repeat and protein kinase domains, and is annotated with transmembrane receptor protein serine/threonine kinase activity, histone H2AS1 kinase activity, signaling receptor activity, and protein kinase activity. It is associated with post-embryonic plant organ development, regulation of floral meristem size, nitrogen fixation, cell wall modification, stomatal complex morphogenesis, heat acclimation, and responses to other organisms. The gene is linked to hormone-mediated signaling, activation of salinity response, and regulation of cell growth. Studies of related genes in other species connect the RLK family to low nitrogen stress tolerance, immunity, and signal transduction. Sequence similarity links the family to traits including seed weight, seed size, plant height, chlorophyll content, root length, proline content, and salt tolerance. The encoded protein localizes to the membrane, plasmalemma, and extracellular regions.
