The plant signaling molecule auxin has been implicated in the control of a confounding multitude of diverse processes in plants, including leaf vascular patterning. In Arabidopsis leaves, expression of the HD-ZIP III gene ATHB8 is initiated in files of isodiametric subepidermal cells that will elong...
