Scientists developed an optimized method for growing brown spot needle blight fungi from infected pine needles and extracting their DNA for research. They tested four different growth media and four DNA extraction techniques to find the best combination. Sabouraud dextrose medium combined with a CTAB-based extraction method containing polyvinylpyrrolidone worked best, producing high-quality DNA suitable for advanced genetic studies. This standardized approach will help researchers better understand this important forest disease.
