The Transcriptional Landscape of Berry Skin in Red and White PIWI ("Pilzwiderstandsfahig") Grapevines Possessing QTLs for Partial Resistance to Downy and Powdery Mildews.

ABSTRACT: PIWI, from the German word Pilzwiderstandsfähig, meaning "fungus-resistant", refers to grapevine cultivars bred for resistance to fungal pathogens such as Erysiphe necator (the causal agent of powdery mildew) and Plasmopara viticola (the causal agent of downy mildew), two major diseases in viticulture. These varieties are typically developed through traditional breeding, often crossbreeding European Vitis vinifera with American or Asian species that carry natural disease resistance. This study investigates the transcriptional profiles of exocarp tissues in mature berries from four PIWI grapevine varieties compared to their elite parental counterparts using RNA-seq analysis. We performed RNA-seq on four PIWI varieties (two red and two white) and their noble parents to identify
