CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G189690 (symbol CBL1, also known as TtCBL1) on durum wheat chromosome 1B encodes a calcineurin B-like protein with EF-hand domains, annotated with calcium ion sensor activity, protein kinase regulator activity, and methylthioadenosine nucleosidase activity. This 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 traits including spot blotch, leaf yellowing tolerance, yield, water stress response, temperature stress response, wheat powdery mildew disease response, photoperiod-sensitive flowering time, submergence tolerance, and root system morphology. 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 family to drought stress response, salt tolerance, potassium deficiency response, and grain size.
