Our research line falls into three areas of fundamental research, that are further combined with an additional directed applied line on important crops attacked by phytopathogenic Pseudomonas bacteria, such as tomato and kiwifruit. My research uses on one side, model plants such as Arabidopsis, Nicotiana and the liverwort Marchantia, to uncover the basic molecular mechanisms controlling hormonal plant immunity and how Pseudomonas bacteria infects hosts though its repertoire of effectors and phytotoxins. On the other side, this generated basic knowledge is directed to study these processes on crops, and to deliver novel strategies for crop protection against two of the most important disease caused by phytopathogenic Pseudomonas, the bacterial speck disease of tomato, caused by P. syringae pv. tomato, and the bacterial canker of kiwifruit, caused by P. syringae pv. actinidiae, by using biotechnology, genome editing, genetic breeding and searching for anti-infective potential novel chemicals among others. The aim is to gain knowledge into the molecular basis of hormonal plant immunity and infection by phytopathogenic Pseudomonas, towards the development of new solutions that could be applied into long-lasting strategies for crop protection against some of the most important diseases caused by Pseudomonas in crops, which negatively affect their cultivation worldwide.

Areas of research:

(1) Chromatin Remodelling Enzymes During Hormonal Signalling in Plant Immunity.

(2) Evolution and Conservation of Immune Plant Hormone Signalling Systems.

(3) Hijacking of Plant Defensive Processes by Bacterial Effectors and Phytotoxins. (4) Applied Crop Research: Inactivation of Bacterial Virulent Systems in Crops.
