Advancing Powdery Mildew Resistance in Gerbera Through CRISPR Gene Editing
Powdery mildew is one of the most persistent and economically damaging diseases affecting gerbera production. While some cultivars show partial resistance, most commercial varieties rely heavily on fungicide applications to maintain quality and marketability. Traditional breeding for resistance is time-intensive and difficult to apply to established cultivars, and transgenic approaches can face significant regulatory hurdles. A recent project, led by Dr. Dayton Wilde and his team at the University of Georgia and supported by AFE, explored a promising alternative: using CRISPR gene editing to develop powdery mildew-resistant gerbera more efficiently. Building a Gene Editing Platform for Gerbera Before targeting disease resistance, researchers first needed to establish reliable tissue culture and transformation systems for gerbera. Optimized protocols were successfully developed for…
