CBL1 — Oryza sativa Japonica

Summary

OsCBL1 (OS01G0598200) on rice chromosome 1 encodes a calcineurin B-like protein with EF-hand domains, annotated with calcium ion sensor activity, protein kinase regulator activity, and methylthioadenosine nucleosidase activity. The gene is associated with responses to drought, salt, temperature, and abiotic stress, as well as grain and panicle traits including grains per panicle and spikelet development. It is linked to nitrogen, phosphorus, calcium, and nitrate responses, and to processes such as monoatomic ion homeostasis, regulation of potassium transport, and cellular response to nitrogen levels. Associations with root system morphology, vegetative vigor, water stress response, and phosphorus content have also been noted. Related genes in other species are associated with salinity tolerance, potassium deficiency response, and cold tolerance.
