RLK — Brassica juncea

Summary

BJUA07G14210S, designated BjRLK, encodes a transmembrane receptor protein kinase with serine/threonine kinase activity, belonging to the PRK1-6/SRF4-like family and containing leucine-rich repeat and protein kinase domains. In Indian mustard (Brassica juncea) on chromosome A07, this gene is associated with post-embryonic plant organ development, regulation of floral meristem size and organ number, floral organ development, gametophyte development, stomatal complex morphogenesis, plant ovule and embryo sac development, heat acclimation, hormone-mediated signaling, response to other organisms, and activation of salinity response. It is also linked to drought tolerance. The encoded protein localizes to the membrane, plasmalemma, and extracellular region. Related genes in other species are linked to low nitrogen stress tolerance, and sequence similarity links the family to traits including stem elongation, stomatal resistance, root length, and plant height.
