CAL1 — Triticum aestivum

Summary

TRAESCS1A02G013600 (symbol CAL1, also known as TAD1) on wheat chromosome 1A encodes a knottins-like domain-containing protein with metal ion sequestering activity and metal binding. This gene is associated with resistance to pathogens, including Fusarium head blight resistance, and has been linked to cellular detoxification of cadmium ion, response to freezing, cold acclimation, and cold tolerance. It is also associated with traits such as spike length, spikelet length, plant height, anther length, and carbohydrate, fructose, sucrose, and carotenoid content. The encoded protein localizes to the extracellular region and is associated with diverse processes including hyphal growth, water transport, cell wall modification, meristem initiation, and anthocyanin accumulation in response to UV light. Studies of related genes in other species link these proteins to pathogen responses.
