RLK — Beta vulgaris subsp. vulgaris

Summary

BvRLK (BVRB_6G127460) on sugar beet chromosome 6 encodes a protein with leucine-rich repeat domains, a serine/threonine/tyrosine kinase catalytic domain, and belongs to the PRK1-6/SRF4-like family. The encoded protein exhibits coreceptor activity, steroid binding, SNARE binding, and protein kinase activity, and is localized to the plasma membrane and endosome. BvRLK is associated with upregulation of seed germination, somatic embryogenesis, skotomorphogenesis, and post-embryonic organ development. It is linked to cellular response to drought, abscission, regulation of defence response to fungi, upregulation of abscisic acid-mediated signaling, and detection of brassinosteroid stimulus. Phenotypic associations include drought tolerance, immune response, and ABA response. Related genes in other species are linked to low nitrogen stress tolerance, and sequence similarity connections extend to traits such as root volume, shoot dry weight, plant height, and lycopene content.
