3rd year graduate seminar

The control of shoot branching in a plant is a highly plastic process and can lead to striking differences in aerial architecture. Recent evidence indicates that canalised auxin transport is a key factor in regulating bud activity and that strigolactone is involved in modulating auxin transport dynamics.

I have been examining the timescale of changes in transcription of the TCP transcription factor, BRC1 (BRANCHED1), during Arabidopsis bud activation to compare it to the timescale over which buds begin measurable growth. In addition, I have been examining the relationship between strigolactone, auxin and BRC1 . These investigations are establishing a framework for the timing of events in bud activation and will help us to understand better how branch growth is regulated.
