CBL1 — Triticum turgidum subsp. durum

Summary

TRITD3BV1G121400, symbol CBL1, encodes a calcineurin B-like protein on durum wheat chromosome 3B. The product contains EF-hand domains and calcium-binding sites, and is annotated with calcium ion binding and kinase binding molecular functions. TtCBL1 is associated with calcium signaling, ABA signaling, thermomorphogenesis, and response to oxidative stress. It localises to the membrane, plasmalemma, and aleurone grain membrane. The gene has been connected to seed dormancy, anthesis time, drought tolerance, salt tolerance, and oxidative stress response. Studies of related genes in other species, including CBL9 and CBL10, link the family to calcium-mediated stress signaling pathways.
