CBL1 — Oryza sativa Japonica

Summary

OsCBL1 (Os02g0291000) encodes a calcineurin B-like protein with calcium ion sensor activity, methylthioadenosine nucleosidase activity, and ATPase inhibitor activity. It is associated with responses to drought, salt, temperature, and abiotic stress, as well as grain and panicle traits, seedling growth, and phosphorus, nitrogen, and calcium homeostasis. The gene is linked to regulation of potassium transport, monoatomic ion homeostasis, raffinose anabolism, and lipid modification. It localizes to the nucleotide-activated protein kinase complex, aleurone grain membrane, and root hair tip. Studies of related genes in other species connect the family to salinity tolerance, potassium acquisition, cold tolerance, and ABA-mediated stress responses.
