CBL1 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G165570, designated TtCBL1 on durum wheat chromosome 1A, encodes a calcineurin B-like protein with EF-hand calcium-binding domains and annotated calcium ion sensor activity, along with 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 salinity. It has been linked to yield, starch grain synthesis, and oleic acid content, as well as spot blotch, powdery mildew, waterlogging, submergence, drought, and heat stress responses. Additional associations include root system morphology, vegetative vigor, photoperiod-sensitive flowering, and plastid development. Related genes in other species are linked to drought, salt, cold, and potassium deficiency responses, as well as grain and panicle traits.
