Autophagy and the Mitochondrial Lon1 Protease Are Necessary for Botrytis cinerea Heat Adaptation

mycolabadmin

Researchers studied how a common plant-damaging fungus called Botrytis cinerea survives high temperatures. They found that two cellular cleanup systems—autophagy (which recycles damaged components) and a mitochondrial protease called Lon1—work together to help the fungus survive heat stress. When either system was disabled, the fungus was much more sensitive to heat and showed increased cell death, suggesting these processes are essential for the fungus’s survival strategy.

First Report of Colletotrichum kahawae Causing Anthracnose on Buckwheat (Fagopyrum tataricum) in China and Biological Characterization of the Pathogen

mycolabadmin

Researchers in China discovered that a fungus called Colletotrichum kahawae is causing a serious disease called anthracnose on buckwheat crops in Yunnan Province. This is the first time this particular fungus has been found on buckwheat, though it’s already known for causing disease on coffee plants worldwide. The scientists characterized how this fungus grows best under certain conditions and tested whether it could infect other important crops like corn, wheat, and potatoes, finding it could potentially harm these crops too.

Comparison and Analysis of the Genomes of Three Strains of Botrytis cinerea Isolated from Pomegranate

mycolabadmin

Researchers compared three strains of gray mold fungus (Botrytis cinerea) that infect pomegranate fruits from different regions in Mexico. Using DNA sequencing and laboratory tests, they found that the MIC strain from Hidalgo was more aggressive at infecting fruit and breaking down plant tissues than the other two strains from the State of Mexico. These differences appear related to each strain’s genetic makeup and where they originated, which could help farmers develop better strategies to prevent gray mold disease on pomegranates.

Whole-genome sequencing of global forest pathogen Diplodia sapinea causing pine shoot blight

mycolabadmin

This study presents a detailed genetic map of Diplodia sapinea, a fungus that causes serious disease in pine trees worldwide. Researchers sequenced the complete genome of a strain from China and compared it with related fungi to better understand how the pathogen causes disease. The high-quality genetic information provides important tools for scientists to develop better ways to prevent and control pine shoot blight, protecting valuable forests and timber resources.

Study of the Herbicidal Potential and Infestation Mechanism of Fusarium oxysporum JZ-5 on Six Broadleaved Weeds

mycolabadmin

Scientists isolated a fungus called Fusarium oxysporum from diseased weeds and tested whether it could help farmers control unwanted plants naturally. The fungus showed strong promise against several common weeds, especially henbit deadnettle, while remaining safe for important crops like barley, wheat, and potatoes. Electron microscope observations revealed that the fungus invades weeds through tiny pores on leaves and spreads across the leaf surface. This discovery offers farmers an environmentally friendly alternative to chemical herbicides for sustainable agriculture.

Isolation, Identification, and In Vitro Fungicide Screening of the Pathogen Associated with Pear Dry Blight

mycolabadmin

Pear dry blight is a serious fungal disease affecting pear orchards in China. Researchers identified the fungus Diaporthe fukushii as the cause and tested various fungicides to find the most effective treatments. The study found that thiophanate-methyl and difenoconazole mixed with propiconazole work best, while some other fungicides are less effective. The research provides farmers with evidence-based strategies to manage this devastating disease.

Complete mitochondrial genome of the fungal pathogen Fusarium oxysporum f. sp. palmarum responsible for fusarium wilt of palms

mycolabadmin

Scientists sequenced the complete genetic material found in the mitochondria of a fungus called Fusarium oxysporum that causes a disease in palm trees. This fungus, which was collected from a sick Mexican fan palm in Florida, destroys palm fronds and can kill the tree. By mapping out this genetic information, researchers now have a better tool to quickly identify and track this harmful pathogen, which will help protect ornamental palm trees.

Phylogenetic diversity of Colletotrichum species (Sordariomycetes, Glomerellales, Glomerellaceae) associated with plant diseases in Thailand

mycolabadmin

Researchers in Thailand studied a common fungal plant pathogen called Colletotrichum that causes diseases like anthracnose and leaf spots on various plants. They identified eight different species of this fungus and discovered two previously unknown species. The study helps farmers and plant scientists better understand and identify these disease-causing fungi to protect their crops.

Morphological and molecular identification of Schizophyllum commune causing storage bulb rot disease of Lanzhou edible lily in China and its biological characteristics

mycolabadmin

Researchers in China identified Schizophyllum commune as a fungal pathogen causing rot in stored edible lily bulbs, marking the first report of this disease. The fungus was identified using microscopic examination and genetic sequencing, and was shown to cause 100% infection on lily bulbs. The study found that the fungus grows best at 30°C with high humidity and darkness, providing important information for controlling this storage disease that causes significant crop losses.

Revisiting the emerging pathosystem of rice sheath blight: deciphering the Rhizoctonia solani virulence, host range, and rice genotype-based resistance

mycolabadmin

Rice plants are affected by a fungal disease called sheath blight caused by a fungus named Rhizoctonia solani. This study found that different strains of this fungus vary in how aggressive they are, with some being much more damaging than others. By testing various rice varieties, researchers identified which ones naturally resist this disease better, and these resistant varieties could be used to breed new rice crops that are less affected by the disease.
