RLK — Brassica napus

Summary

BnRLK (DARMORV10_A07P16680.1) on chromosome A07 of oilseed rape encodes a transmembrane receptor protein kinase with serine/threonine kinase activity, containing leucine-rich repeats and a calponin homology domain. The gene is associated with cell wall thickening, stomatal closure and complex morphogenesis, floral organ development and specification of organ number, regulation of meristem organisation and floral meristem size, gametophyte development, embryogenesis, plant ovule development, hormone-mediated signalling, and response to stress and chitin. It is linked to stomatal resistance and localises to the plasma membrane and extracellular region. Related genes in other species are linked to low nitrogen stress tolerance, and broader sequence similarity links suggest associations with plant height, root length, stem elongation and drought tolerance.
