Initiation of aboveground organ primordia depends on combined action of auxin, ERECTA family genes, and PINOID.

Plant physiology - 29 Aug 2022

DeGennaro Daniel, Urquidi Camacho Ricardo Andres, Zhang Liang, Shpak Elena D

Abstract excerpt

Leaves and flowers are produced by the shoot apical meristem (SAM) at a certain distance from its center, a process that requires the hormone auxin. The amount of auxin and the pattern of its distribution in the initiation zone determine the size and spatial arrangement of organ primordia. Auxin gradients in the SAM are formed by PIN-FORMED (PIN) auxin efflux carriers whose polar localization in the plasma...
