ACT1 — Pisum sativum

Summary

PsACT1 (PSAT3G166680) encodes an actin isoform (PEAc14-1) that is a structural constituent of the cytoskeleton, possesses ATP binding and hydrolase activity, and belongs to the actin/actin-like conserved family. In garden pea, this gene is associated with actin polymerization or depolymerization, root hair elongation, nuclear movement, protein import, circadian rhythm, and sporulation. It has also been linked to insemination, sperm motility, sperm capacitation, and the acrosome reaction, as well as microtubule assembly. The encoded protein localizes to the actin cytoskeleton. Studies of related genes in other species connect the family to traits including plant height, drought tolerance, germination rate, seed maturation, seed coat color, stomatal opening, and flower abortion.
