Endosperm Degradation in Seeds

My research is focussed on the process of endosperm degradation during seed development, using Arabidopsis as a model system. Specifically, I am employing a reverse genetic screen to identify enzymes involved in a putative process in which sugars are recycled from the cell walls of the degrading endosperm to the growing embryo. In addition to probing the genetics of this pathway, I will be analysing the biochemical and physiological basis of cell wall sugar recycling during embryo development, seed germination, and early seedling growth.

Biography & research interests

I was graduated from the University of Cambridge (Natural Science Tripos) in 2013 and completed my PhD at the University of Edinburgh in 2017. My PhD was focused on RNA silencing-based antiviral immunity in plants. During my PhD studies, I also began working with CRISPR genome editing techniques in the context of plant antiviral resistance. I was awarded an AgreenSkills+ fellowship to undertake my first postdoc position, from November 2017, at the Reproduction and Development of Plants lab at the École Normale Supérieure de Lyon. Currently I am using existing and novel genome editing methods to conduct a reverse genetic screen to better understand the molecular basis of endosperm degradation and cell wall sugar recycling during seed germination in Arabidopsis thaliana.
