Research Description

My lab is interested in elucidating the roles of vesicular trafficking in innate immunity, focusing on host clathrin-coated vesicle (CCV) components with novel roles in immune signaling and responses to Pseudomonas syringae bacteria. This research interest has been ignited by my cross-diciplinary postdoctoral training in sterol requirement in yeast endocytosis (Prof. Howard Riezman, Biozentrum, Basel, Switzerland) and syntaxin phosphorylation in fungal immune signaling (Cf-9/Avr9) (Prof. Jonathan Jones, Sainsbury Laboratory, England).

The plasma membrane (PM) provides a critical interface between eukaryotic cells and their environment to control cellular responses. In the model plant Arabidopsis, the cellular mechanisms and molecular machineries regulating the PM proteome remain largely elusive. One strategy that cells use to control the protein composition of the PM is protein cargo trafficking to and from the PM by vesicular trafficking. Vesicular trafficking is the movement of cargo proteins from one organelle to another in form of small, membrane bound vesicles.

We utilize the plant immune receptor FLAGELLIN SENSING 2 (FLS2) that detects bacterial flagellin or its active peptide-derivative flg22. FLS2 needs to reside at the PM to perceive flg22 for effective immune responses. A multifaceted vesicle trafficking network is essential for ensuring that FLS2 localizes correctly to its site of function (the PM) and in the correct abundance. However, considering the complexity of the vesicular trafficking network, relatively little is known about the identity and role(s) of vesicle components that function in flg22-signaling and/or trafficking of FLS2.

My lab focusses on identifying vesicle components of the clathrin-coated vesicle (CCV) network with novel roles in immune signaling and/or trafficking of FLS2 and other proteins with immune functions to and from the cell surface. Our efforts center on CCV components that function in endocytosis and secretion at the PM and the trans-Golgi network, respectively.

To address these questions, we use a combination of interdisciplinary techniques including biochemical, cell biological, proteomic, metabolomics, genetic, molecular biological and live-cell imaging approaches. Recently, we have started to expand our work from roles of CCV components in innate immunity to nutrient acquisition in Arabidopsis and the crop maize.
