Arsenic Stress Resistance in the Endophytic Fungus Cladosporium cladosporioides: Physiological and Transcriptomic Insights into Heavy Metal Detoxification

mycolabadmin

A special fungus called Cladosporium cladosporioides, found living inside the roots of Gentiana yunnanensis (a traditional Chinese medicine herb), can tolerate extremely high levels of arsenic. Researchers discovered that this fungus protects itself from arsenic poisoning by storing arsenic mostly in its cell walls, converting toxic arsenic into less harmful forms, and activating its antioxidant defense systems. This discovery could help reduce arsenic contamination in medicinal herbs and lead to new methods for cleaning arsenic-polluted soil.

Identification, biological characteristics, and screening of control agents against root rot of Ardisia crenata Sims in China

mycolabadmin

Researchers identified a fungus called Fusarium cugenangense as the cause of root rot disease in Ardisia crenata, a valuable traditional Chinese medicinal plant. The disease was affecting 25-35% of plants in Chongqing farms and damaging their roots. Scientists tested various pesticides and found that fluazinam chemical spray and zhongshengmycin biological spray were the most effective at stopping the fungus, providing farmers with effective treatment options.

Pathogen identification and biological fungicides screening for Plumbago auriculata blight in China

mycolabadmin

Researchers in China identified a fungal disease affecting Plumbago auriculata (cape leadwort), a popular ornamental plant. The disease was caused by Fusarium ipomoeae, a fungus that causes yellowing and death of plant tissue. Scientists tested seven biological pesticides and found that osthole, a natural compound, was most effective at controlling the fungus and preventing disease.

Postharvest Disease Management of ‘Akizuki’ Pear in China: Identification of Fungal Pathogens and Control Efficacy of Chlorine Dioxide

mycolabadmin

‘Akizuki’ pears are a popular fruit in China but often develop rot diseases during storage, causing significant economic losses. Researchers identified four types of fungi responsible for this rot and tested chlorine dioxide gas as a treatment. The study found that chlorine dioxide effectively kills these fungi by damaging their cell membranes and works as well as commercial fungicides, offering a safer alternative for preserving pears without harmful chemical residues.

Biological characterization and in vitro fungicide screening of a new causal agent of walnut leaf spot in Guizhou Province, China

mycolabadmin

Researchers in China discovered that a fungus called Didymella segeticola is causing a serious leaf spot disease in walnut trees in Guizhou Province. They studied how this fungus grows under different conditions and tested 20 different fungicides to find the most effective treatments. Two fungicides—difenoconazole and tetramycin—were found to be particularly effective at stopping the fungus, offering practical solutions for protecting walnut crops.
