CBL1 — Triticum turgidum subsp. durum

Summary

TRITD5AV1G093590, symbol CBL1, encodes a calcineurin B-like protein on durum wheat chromosome 5A. The product contains EF-hand domains and binds calcium ions and kinases. This gene is associated with calcium signaling, ABA signaling, thermomorphogenesis, and response to oxidative stress, and is localized to the membrane, plasmalemma, and aleurone grain membrane. It is associated with seed dormancy, anthesis time, drought tolerance, oxidative stress response, and salt tolerance. Related genes in other species link the family to calcium-dependent stress signaling and ion homeostasis, though these functions are not yet established for TtCBL1 itself.
