Arp2/3 and 'The Shape of things to come'

摘要

The shape of plant cells is reliant upon an organised actin network. A series of recent publications have emphasised the central role played by the actin-nucleating Arp2/3 complex in plant growth. In animals and fungi, the Arp2/3 complex influences cell motility and morphogenesis through its ability to nuclease actin filaments locally in response to cell signalling pathways. There are potential parallels in the action and control of the Arp2/3 complex in plants and animals.
