ACT7 — Glycine max

Summary

GLYMA_06G150100V4, designated GmACT7 or ACT7, encodes an actin protein on soybean chromosome 6. It is annotated as a structural constituent of the cytoskeleton and has ATP binding, hydrolase activity, and protein phosphorylated amino acid binding. The gene is associated with the actin cytoskeleton and localizes to multiple cellular compartments including the chloroplast envelope, plant-type cell wall, plasmodesma, and Golgi complex. GmACT7 is associated with seed coat color, nitrate uptake, germination rate, plant height, drought tolerance, and leaf composition traits. It is linked to root growth, root hair elongation, seed germination, disease resistance, polar auxin transport, callus formation, salt stress adaptation, and tissue development. Studies of related genes in other species connect the actin family to actin filament organization, organ size, calcium signaling, and phenotypes including dwarfism, reduced root hairs, and delayed callus formation.
