Anti-Therapeutic Action: canker formation

Species diversity of Cytospora associated with forest canker diseases in Xizang (Tibet), China

mycolabadmin

Scientists studying forests in Tibet discovered 23 new species of Cytospora fungi that cause canker diseases in trees like poplars and willows. Using advanced genetic analysis combined with traditional microscopic examination, researchers identified a total of 50 Cytospora species in the region. These fungi cause bark damage and branch death in many important forest trees. Understanding which species are present and how they spread is crucial for protecting Tibet’s valuable forest ecosystems.

Study on Pathogenesis of Cytospora pyri in Korla Fragrant Pear Trees (Pyrus sinkiangensis)

mycolabadmin

Researchers identified Cytospora pyri as the fungus causing a serious canker disease in Korla fragrant pear trees grown in Xinjiang, China. The fungus cannot directly infect healthy bark but requires wounds to enter trees, then spreads rapidly through tissues using powerful cell-degrading enzymes. Understanding these infection mechanisms can help farmers prevent the disease by protecting trees from injuries and maintaining tree health.

Pomegranate Woody Mycobiota Associated with Wood Decay

mycolabadmin

Pomegranate growers in Italy are facing a serious disease called wood decay syndrome that kills young trees. Researchers found that multiple fungi, especially Neofusicoccum parvum and several Diaporthe species, working together cause this disease. Cold winter temperatures appear to weaken the trees, making them vulnerable to these fungal infections. Using both traditional lab methods and modern DNA analysis, scientists identified the fungi and confirmed which ones are most dangerous.
