Unveiling the Culprit: DNA Technology Solves South Africa's 40-Year-Old Pine Tree Mystery

DNA sequencing technology has finally identified the culprit behind a mystery disease that has been killing pine trees in South Africa's Western Cape province for over 40 years. The pathogen responsible for the disease outbreak was identified as Rhizina undulata, exonerating the long-time suspect, Leptographium serpens. The trigger that activated the fungus in the plantations remains unknown, but the sandy and acidic soil in which the trees were planted may have played a role. The discovery of the true culprit provides valuable data for understanding the biology of the fungus and developing better control strategies in the future. This study highlights the importance of preserving diverse fungal cultures and investing in research and technological advancements.
