WebNuclei undergo dynamic shape changes during plant development, but the mechanism is unclear. In Arabidopsis, Sad1/UNC-84 (SUN) proteins, WPP domain-interacting proteins (WIPs), WPP domain-interacting tail-anchored proteins (WITs), myosin XI-i, and CROWDED NUCLEI 1 (CRWN1) have been shown to be essential for nuclear elongation in various … WebMyosins constitute a large multigene family of actin-based molecular motors, which are essential to eukaryotic homeostasis across the phylogenetic spectrum. Myosins are …
