CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G189370 (symbol CBL1) on durum wheat chromosome 1B encodes a calcineurin B-like protein with EF-hand domains. The gene is associated with calcium ion sensor activity, methylthioadenosine nucleosidase activity, ATPase inhibitor activity, protein kinase regulator activity, protein kinase activator activity, maltose binding, calcium-dependent protein serine/threonine phosphatase activity, voltage-gated monoatomic anion channel activity, Kir channel activity, ABC-type indole transporter activity, cadmium ion transmembrane transporter activity, efflux permease activity, small GTPase binding, and PI4K activity. It is linked to thermomorphogenesis, monoatomic ion homeostasis, regulation of potassium transport, response to pH, cellular responses to nitrogen levels, and hypotonic salinity response. Associations with agronomic traits include spot blotch, leaf yellowing tolerance, yield, vegetative vigor, root system morphology, water stress response, temperature stress response, photoperiod-sensitive flowering time, wheat powdery mildew disease response, submergence tolerance, and starch grain synthesis. The protein localises to the calcineurin complex, protein serine/threonine phosphatase complex, root hair tip, pollen tube, and aleurone grain membrane. Related genes in other species link the family to drought, salt, cold, and potassium deficiency responses, as well as seed oil content and grain traits.
