Abstract

Complementary interaction between the AGAMOUS and PINOID/ABRUPTUS genes was revealed. In double mutant abr ag-1, there is a significant increasing proliferation of cells of the floral meristem and formation of branching shoot-like flowers. These data indicate the participation of the PID/ABR gene in limitation of stem cells proliferation in the floral meristem. The revealed increase of transcription level of WUS gene in flowers of the abr mutant, as well as distortion of auxin distribution, allow us to suggest that the PID/ABR gene controls auxin transport and participates in positioning of expression domains for the WUS gene.
