    Research Interests

    Research in the Plant Biochemistry Lab focuses on the role of protein degradation mediated by the ubiquitin system in the regulation of plant responses to biotic and abiotic stresses.

    For this work, we use the model plant Arabidopsis thaliana, but also crops such as barley and Brassica rapa (turnip), in combination with biochemical, molecular, genetic and genomics approaches. More specifically, we aim at understanding how the nature of the N-terminal residue of proteins affects their stability and participates to the regulation of plant-pathogen interactions. Another aspect of the work aims at gaining further insights into the role of protein degradation in the regulation of transcription in the context of biotic and abiotic stresses.

    The Plant Biochemistry Lab is a member of the Virtual Irish Centre for Crop Improvement (VICCI). Additional details available at: http://vicci.ie/
