Short description of ongoing research projects

The main objective of our research is to contribute to uncovering the role of the plant specific RNA polymerases – Pol IV and Pol V in the transcriptional control of plant stress response. We are looking for connection between methylation status and expression levels of stress-responsive protein-coding genes and of microRNA genes.
