ARA1 — Triticum turgidum subsp. durum

Summary

TRITD7BV1G172950 (symbol ARA1, also known as CAP1, TtCAP1, TtISA1, ISA1, TtARA2, ARA2) on durum wheat chromosome 7B encodes a GHMP kinase C-terminal domain-containing protein with L-arabinokinase and galactokinase activities, and binds ATP. The gene is associated with galactose metabolism, starch anabolism, and carbohydrate metabolism, and its product localizes to the plasmodesma, cytosol, and cytoplasm. It has been linked to polysaccharide content, amylopectin structure, auxin sensitivity, lateral root number and development, arabinose metabolism and toxicity, carbon energy status signaling, sugar signalling, pollen development, grain traits, cell wall composition, and growth. Related genes in other species are associated with starch synthesis and metabolism, and with starch biosynthesis and anther development.
