OSK1 — Camelina sativa

Summary

CSA19G002550 (OSK1, CsKIN10) encodes a protein with AMP kinase activity, protein kinase regulator activity, and multiple additional molecular functions including cyclin-dependent protein kinase inhibitor activity, SUMO transferase activity, and phosphatase binding. It contains a protein kinase domain, KA1 domain, and UBA domain. In Camelina sativa, this gene is associated with the establishment of petal orientation, perianth and sepal development, negative regulation of gibberellin biosynthesis, cellular responses to glucose starvation, nitrogen levels, and cytokinin stimulus, as well as mitochondrial and peroxisome fission. It is linked to numerous agronomic traits including seed protein content, oleic acid content, iron concentration, vegetative vigor, relative growth rate, branch angle, peduncle length, petal size, floral organ number, and responses to water stress, nitrogen, phosphorus, alkali soil, UV light, and pathogens such as cucurbit downy mildew and wheat powdery mildew. Related genes in other species are associated with seed development, drought and salt tolerance, germination, root elongation, and cell cycle regulation.
