ARA1 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G225340, designated ARA1 on durum wheat chromosome 7A, encodes a GHMP kinase domain-containing protein with L-arabinokinase and galactokinase activities. The gene is associated with galactose metabolism, starch anabolism, and localizes to the cytosol and plasmodesmata. It has been connected to polysaccharide content, amylopectin structure, arabinose metabolism and toxicity, carbon-energy status signaling, sugar signaling, auxin sensitivity, lateral root development, pollen development, grain traits, cell wall composition, and growth. Studies of related genes in other species link the family to starch synthesis and metabolism, starch biosynthesis, and anther development. Sequence similarity further associates the family with grain weight, size, and appearance, amylose and starch content, seed weight, starch mobilization, pollen fertility, root morphology, and wheat stripe rust disease response.
