COST ACTION CA20110 – ExRNA-PATH (https://exrnapath.eu/) is now in its final year. This Action focuses on RNA communication across kingdoms, with a significant aim of developing strategies for pathogen control. Participation in COST Action has provided our lab with the opportunity to start developing of novel strategies for protecting poppy against pathogens and pests.

Papaver somniferum (poppy) is a traditional culinary ingredient and a important oilseed crop in Central and Eastern Europe. The current EU "farm to fork" strategy challenges disease management in poppy by reducing available fungicides and pesticides. Our research focuses on two protective approaches: effective gene editing in poppy and the development of RNAi-based fungicides. We study poppy immune responses and are concurrently establishing protocols for poppy transformation and pathosystems (Botrytis cinerea, Sclerotinia sclerotiorum, Alternaria papavericola, Aphis fabae) under controlled conditions. Our work involves designing and testing dsRNA sequences for spray-induced gene silencing (SIGS) against pathogens and pests within our available pathosystems. If successful, these strategies will significantly enhance poppy protection against pathogens and pests.
