Boosting genetic immunity of pea against downy mildew pathogen

Pea (Pisum sativum) is an essential crop for sustainable agriculture, valued for its nitrogen-fixing capabilities and as a key source of plant-based protein. However, downy mildew (DM), caused by the pathogen Peronospora viciae f. sp. pisi, poses a significant threat to pea production in the UK, leading to annual yield losses exceeding £10 million. With limited varietal resistance and the regulatory ban on fungicidal seed treatments, there is an urgent need for innovative strategies to combat DM and restore grower confidence in pea production.
