Function

function

Together with ARGOS and ARL, regulates organ growth and final organ size. Promotes both cell expansion and proliferation-dependent organ growth, in an ANT-dependent manner.

Expression

Tissue specificity

Mostly expressed in flowers, and, to a lower extent, in leaves and cotyledons.

Induction

Induced by ethylene but repressed by abscisic acid (ABA) and epi-brassinolide (epi-BL) treatments.

Developmental stage

Detected in leaf primordia. In leaves, present in the blade and the petiole, especially at the dispersed meristematic regions and the leaf margin. Accumulates in floral organs.
