CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G132830, designated TtCBL1 on durum wheat chromosome 1B, encodes a protein with calcium ion sensor activity, methylthioadenosine nucleosidase activity, and protein kinase regulator 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, vegetative vigor, root system morphology, iron content, phosphorus response, photoperiod-sensitive flowering time, submergence tolerance, and wheat powdery mildew disease response. Localization evidence connects the product to the nucleotide-activated protein kinase complex, aleurone grain membrane, root hair tip, and pollen tube. Studies of related genes in other species link the CBL family to drought stress response, potassium deficiency tolerance, and grain protein content.
