CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G194230 (symbol CBL1, also known as TtCBL1) on durum wheat chromosome 1B encodes a calcineurin B-like protein, a member of the CNBL1-10 family containing EF-hand domains that bind calcium ions. The gene product is associated with kinase binding and calcium ion binding, and is linked to thermomorphogenesis, calcium signaling, response to oxidative stress, and ABA signaling. It localizes to the membrane, including the plasmalemma and aleurone grain membrane. Associations with agronomically important traits include seed dormancy, anthesis time, drought tolerance, and salt tolerance (SALTTL). Related genes in other species further connect this gene family to calcium-mediated stress signaling pathways.
