powdery mildew control

Multi-locus phylogenetic network analysis of Ampelomyces mycoparasites isolated from diverse powdery mildews in Australia and the generation of two de novo genome assemblies

Scientists discovered and studied 20 new species of a beneficial fungus called Ampelomyces that naturally attacks powdery mildew, a common plant disease found in Australia. They created detailed genetic maps of two of these fungal strains to better understand how they work as biological control agents. This research could help develop better natural ways to protect crops like grapes and vegetables from powdery mildew without using chemical pesticides.

Hidden treasures of herbaria – even small collections contain a wealth of diversity: the powdery mildews of the North Carolina State Larry F. Grand Mycological Herbarium

This study examined a collection of powdery mildew fungi preserved in a university herbarium and used DNA analysis to identify which specimens had been misidentified over the years. The researchers found that about 83% of the specimens had incorrect identifications and discovered four completely new species that look very similar to known species but are genetically distinct. The findings show that old museum collections are valuable resources for discovering hidden biodiversity and that we should preserve these collections rather than discard them.
