AAC1 — Triticum aestivum

Summary

TRAESCS6B02G240500, designated TaAAC1 on bread wheat chromosome 6B, encodes an actin-related protein 3 that is a structural constituent of the cytoskeleton, binds actin and ATP, and possesses hydrolase activity. The gene is associated with actin filament branch nucleation, root hair elongation, seed germination, and responses to mannitol, hypoxia, and stress. It is linked to starch and DNA metabolism, epigenetic regulation of gene expression, vesicle transport, the cell cycle, and syngamy. TaAAC1 localises to the actin cytoskeleton, nucleus, and inner dynein arm. Associations with agronomic traits include grain shape, grain length, grains per spike, grain size, plant height, protein and chlorophyll content, stripe rust, drought tolerance, and germination rate. Related genes in other species connect the family to the Arp2/3 protein complex.
