CBL1 — Brachypodium distachyon

Summary

BRADI_3G43510V3 (BdCBL1) on chromosome 3 of Brachypodium distachyon encodes a calcineurin B-like protein containing EF-hand domains, with annotated calcium ion sensor activity, methylthioadenosine nucleosidase activity, and protein kinase regulator activity. The gene is associated with monoatomic ion homeostasis, regulation of potassium transport, response to pH, cellular response to nitrogen levels, and hypotonic salinity response. It has been linked to traits including spot blotch, leaf yellowing tolerance, fruit set trait, alkali soil sensitivity, root system morphology trait, vegetative vigor, iron content trait, phosphorus response, water stress response trait, nitrogen sensitivity, photoperiod-sensitive flowering time trait, submergence tolerance, and yield trait. Studies of related genes in other species link the family to drought stress response, growth, and abiotic stress tolerance, while related genes in other species connect it to potassium deficiency response, cold tolerance, and seed oil content.
