The interaction between Hyaloperonospora arabidopsidis (Hpa) and Arabidopsis is a very useful system to understand the molecular mechanisms of plant immunity.

Pathogen effectors subvert host immunity to successfully colonize the plant. Plants have evolved disease resistance (R) proteins. These recognize effectors either directly or indirectly, and activate effector-triggered immunity (ETI). In the first part, I am interested in the recognition of Hpa effector ATR2 by RPP2A and RPP2B.

Also, HaRxL effectors are thought to manipulate diverse aspects of host physiology for the benefit of the pathogen. Approximately one third of the HaRxLs localize exclusively to the plant cell nucleus and several candidates interact with transcription factors. In the second part, based on previous screenings I focused to around 10 nuclear HaRxLs for further characterization. I am aiming to identify the host targets of these HaRxLs and we will test how they affect early and late read-outs of plant immunity.
