CBL1 — Oryza sativa Japonica

Summary

OsCBL1 (Os02g0291400) encodes a calcineurin B-like protein with EF-hand calcium-binding domains, annotated with calcium ion sensor activity, methylthioadenosine nucleosidase activity, and protein kinase regulator activity. In rice, this gene is associated with responses to drought, salt, temperature, and abiotic stress, as well as grain and panicle traits including grains per panicle. It has been linked to phosphorus, nitrogen, calcium, and nitrate responses, and to processes such as monoatomic ion homeostasis, regulation of potassium transport, and cellular response to nitrogen levels. The gene is also associated with spot blotch, leaf yellowing tolerance, alkali soil sensitivity, and root system morphology. Related genes in other species are linked to calcium binding, salt and cold tolerance, potassium acquisition, and photoperiodic flowering.
