text: Germline determination is essential for species survival and evolution in
multicellular organisms. In most flowering plants, formation of the female germline
is initiated with specification of one megaspore mother cell (MMC) in each ovule;
however, the molecular mechanism underlying this key event remains unclear. Here
we report that spatially restricted auxin signaling promotes MMC fate in Arabidopsis.
Our results show that the microRNA160 (miR160) targeted gene ARF17 (AUXIN RESPONSE
FACTOR17) is required for promoting MMC specification by genetically interacting
with the SPL/NZZ (SPOROCYTELESS/NOZZLE) gene. Alterations of auxin signaling cause
formation of supernumerary MMCs in an ARF17- and SPL/NZZ-dependent manner. Furthermore,
miR160 and ARF17 are indispensable for attaining a normal auxin maximum at the
ovule apex via modulating the expression domain of PIN1 (PIN-FORMED1) auxin transporter.
Our findings elucidate the mechanism by which auxin signaling promotes the acquisition
of female germline cell fate in plants.
