CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G202220 (symbol CBL1, also known as TtCBL1) on durum wheat chromosome 1A encodes a calcineurin B-like protein containing EF-hand calcium-binding domains and is annotated with calcium ion sensor activity, protein kinase regulator activity, and ATPase inhibitor activity. The gene is associated with thermomorphogenesis, monoatomic ion homeostasis, regulation of potassium transport, and responses to pH, nitrogen levels, and salinity. It has been linked to spot blotch, leaf yellowing tolerance, water stress response, nitrogen and potassium sensitivity, photoperiod-sensitive flowering time, and wheat powdery mildew disease response. Additional associations include root system morphology, vegetative vigor, iron content, starch grain synthesis, and submergence tolerance. Studies of related genes in other species connect the CBL family to drought stress, salt tolerance, potassium deficiency response, and seed oil content.
