Mobile gibberellin directly stimulates Arabidopsis hypocotyl xylem expansion.

The Plant cell - 1 Apr 2011

Ragni Laura, Nieminen Kaisa, Pacheco-Villalobos David, Sibout Richard, Schwechheimer Claus, Hardtke Christian S

Abstract excerpt

Secondary growth of the vasculature results in the thickening of plant structures and continuously produces xylem tissue, the major biological carbon sink. Little is known about the developmental control of this quantitative trait, which displays two distinct phases in Arabidopsis thaliana hypocotyls. The later phase of accelerated xylem expansion resembles the secondary growth of trees and is triggered upon...
