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

mycolabadmin

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.

Saprotrophic Arachnopeziza Species as New Resources to Study the Obligate Biotrophic Lifestyle of Powdery Mildew Fungi

mycolabadmin

Scientists have created a new way to study powdery mildew fungus, which causes widespread plant disease but cannot normally be studied in the laboratory. They identified a related fungus species (Arachnopeziza) that can grow in culture and can be genetically modified. By sequencing the DNA of these two Arachnopeziza species and developing methods to alter their genes, researchers have created a practical tool to understand how powdery mildew becomes dependent on its plant host, potentially leading to better disease control strategies.

Biochemical characteristics of extracts from proallergenic microfungi Erysiphe palczewskii and Erysiphe convolvuli

mycolabadmin

Researchers studied two types of fungi that cause powdery mildew on plants and can trigger allergies in people who breathe in their spores. They discovered that these fungi contain proteins that act as allergens, including special proteins that help fungi survive stress. The fungi also contain high levels of linoleic acid, a fatty acid that can increase inflammation in the body. This research helps scientists understand why these fungi can cause allergic reactions and could help develop better diagnostic tools for fungal allergies.

New records of powdery mildew fungi on stone fruits from India

mycolabadmin

Researchers in Kashmir have identified three types of powdery mildew fungi that infect peach, plum, and apricot trees. These are new diseases documented in India and Asia for these important fruit crops. Scientists used both traditional microscopy and modern DNA sequencing to identify the fungi, providing farmers with accurate information needed to manage these plant diseases effectively.

Twenty-nine new host records of powdery mildew fungi (Erysiphaceae) in Taiwan with an updated checklist

mycolabadmin

Researchers updated Taiwan’s list of powdery mildew fungi, which are harmful plant pathogens affecting crops and trees worldwide. By collecting specimens from various locations and analyzing them using genetic sequencing and microscopy, they identified 29 new host-fungus combinations, with six Erysiphaceae species documented in Taiwan for the first time. The updated checklist now includes approximately 109 powdery mildew species known to affect 246 different host plant species across 75 plant families in Taiwan.
