ACT — Nicotiana attenuata

Summary

A4A49_56350, designated ACT1 in coyote tobacco (Nicotiana attenuata, scaffold00338), encodes a protein with structural constituent of cytoskeleton, hydrolase activity, and ATP binding, belonging to the actin/actin-like and ATPase NBD families. The gene is associated with actin nucleation, pronuclear migration, karyogamy, nuclear movement, double fertilization, syngamy, root hair elongation, and regulation of gene expression. It is linked to the actin cytoskeleton and nucleus. The gene has been connected to cytokinin content. Studies of related genes in other species link the family to ATPase activity (EC 3.6.4.-).
