ARA1 — Triticum turgidum subsp. durum

Summary

TRITD6AV1G035020 (symbol ARA1) on durum wheat chromosome 6A encodes a GHMP kinase N-terminal domain-containing protein with L-arabinokinase and galactokinase activities, and binds ATP. It is associated with galactose metabolism, starch anabolism, and carbohydrate metabolism, and localises to the plasmodesma, cytosol, and cytoplasm. The gene is associated with polysaccharide content, amylopectin structure, auxin sensitivity, lateral root number and development, arabinose metabolism and toxicity, carbon energy status signalling, sugar signalling, pollen development, vegetative growth, grain traits, and cell wall properties. Related genes in other species are linked to starch synthesis and metabolism, starch biosynthesis, anther development, grain weight, size, appearance, amylose content, starch content, seed weight, sugary and floury endosperm, pollen fertility, root morphology, and wheat stripe rust disease response.
