Regulation of preprocambial cell state acquisition by auxin signaling in Arabidopsis leaves.

Development (Cambridge, England) - 1 Oct 2009

Donner Tyler J, Sherr Ira, Scarpella Enrico

Abstract excerpt

The principles underlying the formation of veins in the leaf have long intrigued developmental biologists. In Arabidopsis leaves, files of anatomically inconspicuous subepidermal cells that will elongate into vein-forming procambial cells selectively activate ATHB8 gene expression. The biological role of ATHB8 in vein formation and the molecular events that culminate in acquisition of the ATHB8 preprocambial cell...
