Project description
Mechanistic roles of second messengers during plant viral infection
Plant viruses hijack plant cells’ endogenous processes to replicate, infecting other cells by moving through plasmodesmata (channels spanning cell walls and linking the cytoplasm of adjacent cells). One way plants react to pathogens is via so-called second messengers like reactive oxygen species (ROS) and calcium that carry the message from cell to cell to trigger defence mechanisms. However, the mechanisms of ROS and calcium during viral infection and the crosstalk between viruses and ROS/calcium signals are largely unknown. With the support of the Marie Skłodowska-Curie Actions programme, the ViROSCa project aims to utilise genome editing, microscopy and biosensors to reveal these, including identifying the virus components that induce the ROS/calcium signalling.
Objective
As sessile organisms, plants always have to deal with different environmental stimuli. The generation of reactive oxygen species (ROS) and calcium flux as second messengers are one of the common strategies to respond to such stimuli. Upon perception of pathogens, molecular warning signals (ROS and calcium) propagate cell-to-cell to trigger defence mechanisms. However, the precise roles of ROS and calcium during viral infection process and the associated signalling mechanism remain largely unknown. Viruses are obligate intracellular pathogens that hijack host machineries to facilitate their replication and propagation across the plant through plasmodesmata, communication channels bridging the plant cells. The ViROSCa project’s goal is to explore the mutual role of generated ROS and calcium signals and to study the crosstalk between the two signals during viral infection and later identify the virus element(s) that specifically induce(s) such signals. I will integrate Arabidopsis genetics, biosensors, genome editing technology (CRISPR/Cas9) and advanced microscopy techniques to decipher the roles of plasma membrane (PM)-located ROS- and calcium related candidate proteins and PM organisation (nanodomains) during the plant virus infection process. The novelty of the project is the use of a powerful pathosystem and biosensors to study the crosstalk between ROS and calcium signalling.
