ACT1 — Phaseolus vulgaris

Summary

PHAVU_008G011000, designated ACT1 or PvACT1, encodes an actin protein on French bean (Phaseolus vulgaris) chromosome 8. The product is a structural constituent of the cytoskeleton with ATP binding and hydrolase activity, belonging to the actin/actin-like conserved domain family. PvACT1 is associated with a wide range of cellular processes, including actin polymerization and depolymerization, cytoplasmic streaming, mitosis, organogenesis, embryogenesis, root hair elongation, cell adhesion, cell death, circadian rhythm, and responses to water. It is linked to nitrogen fixation and nodulation. The protein localizes to the actin cytoskeleton and nucleus. Studies of related genes in other species connect the family to traits such as drought tolerance, plant height, germination rate, seed maturation, seed coat color, stomatal opening, and flower abortion, though these associations are not yet established in French bean.
