GRIK1 — Brassica oleracea var. botrytis

Summary

BoGRIK1 (GRIK1) on cauliflower chromosome 3 encodes a protein with protein serine/threonine kinase activity and protein kinase activity, and belongs to the MFS spinster-like family. It is associated with the mevalonate pathway, starch metabolism, sugar-mediated signalling, response to glucose, hypoxia, salt, oxidative stress, herbicide, and virus, as well as positive regulation of autophagy, regulation of leaf senescence, vegetative phase change, transition to reproductive phase, primary root development, and plant organ development. The gene is linked to numerous traits including drought tolerance, submergence tolerance, high temperature stress response, oxidative stress response, abscisic acid sensitivity, flowering time, seed yield, leaf senescence, root development, and seedling growth. It localises to the nucleus, cytosol, Golgi complex, and plasmalemma. Studies of related genes in other species connect the family to energy sensing, starch mobilisation, circadian entrainment, and developmental transitions.
