RLK — Beta vulgaris subsp. vulgaris

Summary

BvRLK (BVRB_9G223890) on sugar beet chromosome 9 encodes a transmembrane receptor protein serine/threonine kinase with coreceptor activity, histone H2AS1 kinase activity, and protein homodimerization activity. The protein belongs to the PRK1-6/SRF4-like family and contains leucine-rich repeats and a protein kinase domain. It is associated with the upregulation of seed germination, abscisic acid-mediated signaling, innate immune response, and response to drought and salinity. The gene is linked to stomatal complex morphogenesis, somatic embryogenesis, regulation of growth, defence response to fungi, and post-embryonic plant organ development. It localizes to the plasma membrane and extracellular region. Phenotype associations include drought tolerance, immune response, and ABA response. Studies of related genes in other species connect the family to traits such as root volume, shoot dry weight, plant height, and abscisic acid sensitivity.
