SCAR mediates light-induced root elongation in Arabidopsis through photoreceptors and proteasomes.

The Plant cell - 1 Oct 2011

Abstract excerpt

The ARP2/3 complex, a highly conserved nucleator of F-actin, and its activator, the SCAR complex, are essential for growth in plants and animals. In this article, we present a pathway through which roots of Arabidopsis thaliana directly perceive light to promote their elongation. The ARP2/3-SCAR complex and the maintenance of longitudinally aligned F-actin arrays are crucial components of this pathway. The...
