CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G199350, designated TtCBL1 on durum wheat chromosome 1A, encodes a calcineurin B-like protein containing EF-hand calcium-binding domains and annotated with calcium ion sensor activity, protein kinase regulator activity, and methylthioadenosine nucleosidase activity. The gene is associated with thermomorphogenesis, monoatomic ion homeostasis, regulation of potassium transport, and responses to pH, nitrogen levels, and hypotonic salinity. It has been linked to yield, spot blotch, leaf yellowing tolerance, water stress response, temperature stress response, wheat powdery mildew disease response, submergence tolerance, vegetative vigor, root system morphology, photoperiod-sensitive flowering time, and starch grain synthesis. Localisation evidence links the product to the nucleotide-activated protein kinase complex, aleurone grain membrane, root hair tip, pollen tube, and nuclear speck. Related genes in other species link the family to potassium deficiency response, cold tolerance, and seed oil content.
