| 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 bine-like flowers. This data indicate the participation of the PID/ABR gene in limitation of proliferating stem cells of 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, allows us to suggest that the PID/ABR gene controls auxin transport and participates in detection of expression domains for the WUS gene. |
