CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G151110 (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, methylthioadenosine nucleosidase activity, and protein kinase regulator activity. This gene is associated with thermomorphogenesis, monoatomic ion homeostasis, regulation of potassium transport, and responses to pH, nitrogen levels, and hypotonic salinity. It is 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, iron content, and photoperiod-sensitive flowering time. Localization evidence connects it to the nucleotide-activated protein kinase complex, aleurone grain membrane, root hair tip, and pollen tube. Related genes in other species link the family to drought tolerance, salt stress, potassium deficiency response, cold tolerance, seed oil content, and grain size.
