Research Description

During plant-pathogen interactions, the plant apoplast (i.e. the extracellular space) is a battlefield. Upon infection, plants secrete proteases into the apoplast, amongst other hydrolytic enzymes. In return, pathogens produce proteases inhibitors to manipulate their host, for instance by suppressing defence responses. My project involves studying the role of apoplastic immune proteases in the defence response of Nicotiana benthamiana to bacterial pathogens. In particular, I study the contribution of serine proteases to plant immunity and their interplay with apoplastic inhibitors.
