Specification of female germline by microRNA orchestrated auxin signaling in Arabidopsis
Abstract
In most flowering plants, a single megaspore mother cell (MMC) is formed in each ovule. Here the authors show that miR160 and the auxin response factor ARF17 act to promote MMC fate via SPL/NZZ and control auxin signaling to prevent somatic cells from acquiring MMC fate.
