I’m interested in plant-microbe interactions and especially how plant resistance proteins recognize pathogen produced effectors. To investigate this question, I’m working in the “Albugo” team of the Jonathan Jones’ group. Albugo candida is an oomycete pathogen of Brassicaceae (including indian mustard, camelina, cauliflower and Arabidopsis thaliana). By analysis between different accessions of A. thaliana, we identified several NB-LRR encoding genes involved in resistance against  A. candida. Some of them share homology but also interesting differences with the TIR-NB-LRR gene pair RPS4/RRS1. By using CRISPR genome editing methods, I’m now trying to elucidate the activation of plant defence induced after recognition of A. candida effector(s).
