CBL1 — Triticum turgidum subsp. durum

Summary

TRITD3AV1G132180, symbol CBL1, encodes a calcineurin B-like protein on durum wheat chromosome 3A. The product contains EF-hand domains and binds calcium ions and kinases. This gene is associated with calcium and ABA signaling, thermomorphogenesis, and response to oxidative stress. It localizes to the membrane, plasmalemma, and aleurone grain membrane. Associations include seed dormancy, anthesis time, drought tolerance, and salt tolerance (SALTTL). Studies of related genes in other species link the family to stress signaling and ion homeostasis, though these roles are not established for TtCBL1 itself.
