Optimization of cultural conditions for pectinase production by Diaporthe isolate Z1-1N and its pathogenicity on kiwifruit

mycolabadmin

Researchers studied how a fungus called Diaporthe causes soft rot in kiwifruit by producing special enzymes called pectinases that break down the fruit’s cell walls. They found the best conditions for growing these enzymes in the lab: a temperature of 28°C, neutral pH around 7.5, and 2-3 days of growth. When they extracted these pure enzymes and put them on fresh kiwifruit, the enzymes caused damage equivalent to about half the damage caused by the living fungus itself, proving these enzymes are important for disease development.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four types of fungi living inside plants without causing harm, called endophytic fungi. These fungi belong to a genus called Diaporthe and were identified using DNA analysis and microscopic examination. The study helps us understand the hidden diversity of fungi living in Korean plants and could lead to discovering new medicines or ways to control plant diseases.

Three New Records of Pathogens Causing Stem Blight on Vaccinium corymbosum in China

mycolabadmin

Researchers in China identified three new fungal species causing stem blight disease in blueberry crops. These fungi infect blueberry stems, causing brown lesions that kill the shoots and leaves. Laboratory tests confirmed all three fungi can cause the disease, with one species being particularly aggressive. This research helps farmers understand and manage this economically important disease that damages 10-25% of China’s blueberry crops.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four previously unknown species of Diaporthe fungi living inside plant tissues without causing visible damage. These fungi were identified using genetic analysis and compared to known species from around the world. The findings show that Korea has more fungal diversity than previously documented and suggest these fungi could potentially be used to develop new medicines or help control plant diseases.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four new species of endophytic fungi called Diaporthe living inside plant tissues without causing visible disease. Using genetic testing and microscopic examination, they identified D. caryae, D. phoenicicola, D. stewartii, and D. unshiuensis as previously unrecorded in Korea. These fungi can potentially produce compounds with medicinal properties or help manage plant diseases. This discovery helps scientists better understand the hidden fungal diversity in Korean ecosystems.

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.
