Aspergillus fumigatus dsRNA virus promotes fungal fitness and pathogenicity in the mammalian host

mycolabadmin

Researchers discovered that a virus infecting the dangerous fungus Aspergillus fumigatus actually helps the fungus survive and cause worse infections in humans. By removing the virus from fungal strains, scientists found that the fungus became weaker and less able to cause disease in mice. Importantly, treating infected mice with an antiviral drug (ribavirin) reduced the viral load and helped the mice survive, suggesting a new approach to treating serious fungal infections.

Microsclerotia formation of the biocontrol fungus Cordyceps javanica IF-1106 and evaluation of its stress tolerance and pathogenicity

mycolabadmin

Researchers studied a fungus called Cordyceps javanica that can be used to control harmful soil nematodes that damage crop roots. The fungus produces special dormant structures called microsclerotia that can survive extreme heat and UV radiation for extended periods. These microsclerotia showed excellent effectiveness at controlling root-knot nematodes on cucumber plants while also promoting plant growth, making them a promising natural alternative to chemical pesticides.

Essential role of sugar transporters BbStp13 in fungal virulence, conidiation, and cell wall integrity in entomopathogenic fungus Beauveria bassiana

mycolabadmin

Scientists studied a fungal protein called BbStp13 that helps a beneficial fungus called Beauveria bassiana attack insect pests. When this protein was removed, the fungus produced fewer spores and couldn’t infect insects as effectively, especially when sugar was scarce. The protein also helps the fungus protect itself from the insect’s immune system. Understanding this protein could help make the fungus better at pest control.

Essential role of sugar transporters BbStp13 in fungal virulence, conidiation, and cell wall integrity in entomopathogenic fungus Beauveria bassiana

mycolabadmin

Researchers studied a fungus called Beauveria bassiana that is used to control insect pests. They found that a protein called BbStp13, which helps the fungus absorb sugars, is crucial for the fungus to infect insects effectively and make spores for spreading. When they removed this protein, the fungus became less dangerous to pests and couldn’t reproduce as well, especially when there wasn’t much food available. These findings could help make this natural pest control method even better.

Aspergillus fumigatus dsRNA virus promotes fungal fitness and pathogenicity in the mammalian host

mycolabadmin

A virus that infects the fungus Aspergillus fumigatus (which causes serious lung infections in humans) actually makes the fungus more dangerous by improving its ability to survive stress and spread disease. Scientists found that removing this virus from the fungus made infections less severe in mice. They also discovered that antiviral drugs like ribavirin could potentially be used to weaken these virus-infected fungi and improve patient survival.

Unveiling microRNA-like small RNAs implicated in the initial infection of Fusarium oxysporum f. sp. cubense through small RNA sequencing

mycolabadmin

Researchers discovered specific small RNA molecules produced by the fungus that causes banana wilt disease. These molecular signals, particularly one called milR106, are critical for the fungus’s ability to infect and damage banana plants. By understanding how these molecules work, scientists can develop better strategies to protect banana crops from this devastating disease that threatens global banana production.
