ACT — Brassica oleracea var. botrytis

Summary

BoACT, on cauliflower chromosome 2, encodes an actin protein containing an actin/actin-like conserved sequence and an ATPase nucleotide-binding domain. It is a structural constituent of the cytoskeleton with hydrolase activity, ATP binding, and protein binding. The gene is associated with actin gel formation, root epidermal cell differentiation, root hair tip growth, responses to high light intensity, red and far-red light, cytokinin, and circadian rhythm. It localises to the actin cytoskeleton, cytosol, cytoplasm, nucleus, and the Cul4-RING E3 ubiquitin ligase complex. BoACT is linked to photosynthetic rate, root morphology, actin filament stability, cytoplasmic streaming, cell elongation, auxin distribution, lateral root formation, isoprenoid biosynthesis, leaf area, and plant fitness. Related genes in other species connect the family to root hair development, actin cytoskeleton organisation, and vegetative development.
