Abstract:Post-embryonic primary root growth is effectively an interplay of several hormone signalling pathways. Here, we show that the ABA-responsive transcription factor ABI3, controls primary root growth through regulation of JA signalling moleculeJAZ1along with ABA responsive factor ABI1. In absence of ABI3, primary root elongation zone is shortened with significantly reduced cell length. Expression analyses and ChIP based assays indicate that ABI3 negatively regulatesJAZ1expression by occupying its upstream regulat… Show more
