Research Interests

Plant genomics, epigenetics, drought, heat.


Penny Tricker obtained her PhD at the University of Southampton (UK) in 2004. She characterized leaf area development and physiology, cell fate specification, water relations and the transcriptome of poplar trees under elevated CO2.

She worked as a postdoctoral research associate with Gail Taylor at the University of Southampton and Angela Karp at Rothamsted Research, contributing to work on forward genetics, association mapping and QTL discovery with environment in both poplar and willow bioenergy crops; making use of the then recently released poplar genome sequence.

As a postdoctoral fellow at the University of Reading with Paul Hadley and Mike Wilkinson, she worked on the epigenetics of cocoa and Arabidopsis in response to the environment and determined the influence of methylation on key stomatal development genes.

At ACPFG, she works in the Genetics Group with Delphine Fleury and has particular responsibility for research on durum wheat. She uses ‘omics data, forward and reverse genetics approaches to try to improve the drought and heat tolerance of wheat and barley.
