ARA6 — Triticum aestivum

Summary

TRAESCS4B02G268600 (symbol ARA6) on wheat chromosome 4B encodes a small GTPase with GTPase activity, GTP binding and protein binding. The gene is associated with Fusarium head blight resistance. ARA6 is associated with vesicle transport, intracellular protein transport, early endosome to late endosome transport, mRNA transport, and endomembrane organization. The encoded protein localizes to the endosome membrane, endocytic vesicles, protein storage vacuole membrane, tonoplast, Golgi membrane, and cytosol. Associations with plant height, drought tolerance, salt tolerance, osmotic stress tolerance, powdery mildew resistance, dark-induced senescence tolerance, sugar and starch homeostasis, glucose content, flowering time, vacuolar transport, and endosomal trafficking have been reported. Related genes in other species are linked to salt stress response and pathogen resistance against Pseudomonas syringae.
