ACT1 — Zea mays

Summary

ZM00001EB216070 (ACT1) on maize chromosome 5 encodes an actin-1 protein, a structural constituent of the cytoskeleton with ATP binding and hydrolase activity, and is localised to the actin cytoskeleton. The gene is associated with a wide range of biological processes including C4 photosynthesis, aerenchyma formation, hormone and carbohydrate transport, mitochondrial transcription, and metabolism of lignin, malate, nucleotide-sugars, and riboflavin. It is linked to numerous agronomically important traits such as grain yield per plant, harvest index, ear diameter, grain filling period, seedling height, leaf width, stem size, root and shoot dry weight, lateral root number, submergence tolerance, drought sensitivity, cell membrane stability, and seed color. Related genes in other species are associated with ATPase activity.
