Research Interests

Pierre Petriacq research interests

I am a plant biochemist who specialises in Mass Spectrometry. My research has primarily focused on plant physiological responses to growth and environmental constraints such as drought and pathogen infections. In particular, I have used '-omics' techniques (specifically transcriptomics and metabolomics) to study the metabolic regulations underpinning redox signalling upon biotic stress. I mostly used the model plant Arabidopsis thaliana for genetic approaches.

As a P3 Independent Research Fellow, I now translate my research into various crops (maize, oilseed rape, tomato, to name but a few). I am involved in many different projects (including, chemical priming, rhizosphere chemistry, impacts of (photo)respiratory pathways and climate change on defence responses, benzoxazinoids signalling) by extensively using Mass Spectrometry techniques (MALDI-, UPLC-q-TOF) to detect adjustments in plant metabolomes. My key research interests are:

  • rhizosphere chemistry: profiling root exudates, benzoxazinoids signalling, in collaboration with Jurriaan Ton
  • metabolic regulations of the plant immune system: priming of plant defences, hormonal balance and (photo)respiration signalling
  • NAD signalling in response to development and stress

Professional Activities

I am a member of the Biological Mass Spectrometry Facility (biOMICS) at the University of Sheffield (http://biomics.group.shef.ac.uk)

  • Alex Williams (impact of CO2 on plant immunity)
  • Will Buswell (chemical priming of plant defences)
