The Role of Nitric Oxide in the Growth and Development of Schizophyllum commune Under Anaerobic Conditions

mycolabadmin

This research shows that nitric oxide (NO) acts like a chemical messenger that helps mushroom fungi grow and reproduce when oxygen is scarce. Scientists studied a fungus found deep below the ocean floor and discovered that NO helps the fungus extend its root-like structures, germinate spores, and even initiate the formation of fruiting bodies (the mushroom stage). When they blocked NO with chemicals, growth slowed down, but when they added extra NO, growth accelerated. This discovery could help us understand how fungi survive in extreme environments with little oxygen.

Cestrum tomentosum L.f. Extracts against Colletotrichum scovillei by Altering Cell Membrane Permeability and Inducing ROS Accumulation

mycolabadmin

Researchers found that extracts from the Cestrum tomentosum plant effectively kill a fungus that causes anthracnose disease in chili peppers. The plant extract works by damaging the fungal cell membranes and causing harmful reactive oxygen species to accumulate inside fungal cells. This natural remedy showed strong protective and therapeutic effects when applied to chili pepper fruits, offering a safer alternative to synthetic chemical fungicides.

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.

Bacillus velezensis LMY3-5 for the biocontrol of soft rot in kiwifruit: antifungal action and underlying mechanisms

mycolabadmin

Scientists discovered a beneficial bacteria called Bacillus velezensis that can effectively prevent soft rot disease in kiwifruit, which causes serious damage during storage. The bacteria works by producing natural antimicrobial compounds that damage the fungal pathogen’s cell walls and membranes, stopping it from growing. This biocontrol approach offers an environmentally friendly alternative to chemical fungicides, reducing pesticide residues while maintaining fruit quality and safety.

Chalkbrood Disease Caused by Ascosphaera apis in Honey Bees (Apis mellifera)—Morphological and Histological Changes in Infected Larvae

mycolabadmin

Chalkbrood is a serious fungal disease that kills honeybee larvae, caused by the fungus Ascosphaera apis. This study examined exactly how the infection progresses by infecting larvae in controlled laboratory conditions and observing them over time under a microscope. The researchers found that once infected, larvae die very quickly within 3-7 days as the fungus spreads throughout their bodies, and the fungus continues to grow even after the larvae are dead, eventually forming visible spores on the dead larvae that spread the disease to other bees in the colony.
