Research focus

Aerial plant architecture is largely determined by the number and activity of axillary meristems (AMs). AMs develop from pools of cells in leaf axils, which are specified by the expression of a set of transcriptional regulators, including LATERAL SUPPRESSOR (LAS). We are characterising the transcriptomes of AM founder cells at different stages of development in annual and perennial plants, to identify genes required for AM formation and use them to modulate shoot architecture in crop plants.
