ACT7 — Glycine max

Summary

GLYMA_04G215900V4, designated GmACT7 or ACT7 on soybean chromosome 4, encodes an actin protein that is a structural constituent of the cytoskeleton and possesses ATP binding, hydrolase activity, and protein phosphorylated amino acid binding. This gene is associated with actin depolymerization, regulation of actin polymerization, cell adhesion, cell migration, and Golgi-to-plasma membrane transport. It localizes to the actin cytoskeleton, chloroplast envelope, plant-type cell wall, nucleolus, plasmodesma, and Golgi complex. GmACT7 is associated with seed coat color, germination rate, plant height, drought tolerance, nitrate uptake, and leaf composition. Phenotypic associations include root growth and hair elongation, seed germination, disease resistance, salt stress adaptation, polar auxin transport, and tissue development. Studies of related genes in other species connect the actin family to actin filament organization, organ size, and calcium signaling.
