CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G138820 (symbol CBL1) on durum wheat chromosome 1A encodes a calcineurin B-like 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, powdery mildew disease response, submergence tolerance, and vegetative vigor. Additional associations include root system morphology, iron content, phosphorus response, photoperiod-sensitive flowering time, and starch grain synthesis. The protein localizes to the nucleotide-activated protein kinase complex, aleurone grain membrane, root hair tip, and pollen tube. Studies of related genes in other species connect the family to drought stress, salt tolerance, grain size, and nitrogen and phosphorus responses.
