The Velvet Complex Is Essential for Sclerotia Formation and Virulence in Sclerotinia sclerotiorum

mycolabadmin

Scientists studied a destructive fungus that damages crops by identifying key genes controlling its ability to form protective resting structures called sclerotia and cause disease. Using genetic screening techniques, they discovered that two genes called SsLae1 and SsVel1 work together as master controllers of both the fungus’s survival and its ability to infect plants. These findings could help develop new ways to control the disease by targeting these critical genes.

Select and Resequence Methods Enable a Genome-Wide Association Study of the Dimorphic Human Fungal Pathogen Coccidioides posadasii

Scientists developed a new method to understand how different strains of the fungus Coccidioides posadasii, which causes Valley Fever, respond to temperature changes. By mixing multiple fungal strains together and sequencing their DNA after growing them at different temperatures, they identified a gene that helps determine whether the fungus grows better in hot (body temperature) or cool (environmental) conditions. This discovery could help explain how this dangerous fungus adapts to human infection and may lead to better treatments for Valley Fever.
