Intraspecies sequence-graph analysis of the Phytophthora theobromicola genome reveals a dynamic structure and variable effector repertoires

mycolabadmin

Researchers sequenced the genome of Phytophthora theobromicola, a newly discovered fungal pathogen that causes serious cacao plant disease. They found the pathogen’s genome is highly variable among different isolates and contains many genes that help it attack cacao plants. By studying which of these harmful genes are active during infection, they identified specific virulence factors unique to this cacao pathogen that could be important targets for future disease control strategies.

Pest categorisation of Pestalotiopsis microspora

mycolabadmin

Pestalotiopsis microspora is a fungus that causes diseases on many cultivated and wild plants including avocado, banana, and kiwi fruit. It has been found in tropical and subtropical regions worldwide and was recently detected in the Netherlands. The fungus can enter the EU through infected plants, fruits, and contaminated soil from other countries. European scientists have determined it meets criteria to be classified as a quarantine pest requiring special phytosanitary measures to prevent its introduction.

Slime molds (Myxomycetes) causing a “disease” in crop plants and cultivated mushrooms

mycolabadmin

Slime molds are not true plant diseases but can harm crops by covering leaves and blocking sunlight and water loss. These organisms prefer wet, organic-rich environments and are particularly problematic in mushroom farming. Farmers can prevent problems by managing moisture, improving ventilation, and removing affected materials, with chemical sprays available as backup options when needed.

Development and Transfer of Microbial Agrobiotechnologies in Contrasting Agrosystems: Experience of Kazakhstan and China

mycolabadmin

Microbial consortia—communities of beneficial microorganisms—offer promising solutions to modern agriculture’s challenges by enhancing plant growth, improving stress tolerance, and restoring soil health. China has successfully integrated these microbial products into farming through strong government support and research infrastructure, while Kazakhstan has the scientific knowledge but faces funding and implementation challenges. This comparative study shows that adopting these technologies requires both scientific advancement and practical support systems tailored to each country’s specific needs.

A review and case study of Rhododendron moulmainense highlights the feasibility and adaptation of evergreen Rhododendron plants to current environmental challenges

mycolabadmin

This study examines Rhododendron moulmainense, a beautiful alpine flowering plant being adapted for urban gardens. Researchers discovered that special soil fungi living in the plant’s roots help it survive stress like drought and heat. The study details multiple ways to grow new plants through cuttings, tissue culture, and seeds, with success rates over 90%. Understanding this plant’s adaptation mechanisms provides strategies for introducing more alpine rhododendrons to lower-altitude cities while improving their resilience to climate challenges.

Exploring fungal pathogens to control the plant invasive Rubus niveus on Galapagos Island San Cristobal

mycolabadmin

Hill raspberry is a problematic invasive plant covering vast areas of the Galapagos Islands and harming native species. Researchers collected diseased Hill raspberry samples and identified five fungal pathogens that naturally infect the plant. These fungi have potential to be developed as biological control agents to manage the invasive species without using chemical herbicides. Further testing is needed to ensure these fungi only target Hill raspberry and do not harm other plants.

Identification of Pseudocercospora mori as the causal agent of grey leaf spot disease in mulberry (Morus atropurpurea) from various localities in Guangdong Province, China

mycolabadmin

Researchers identified a fungus called Pseudocercospora mori as the cause of grey leaf spot disease in mulberry trees grown in Guangdong Province, China. Using advanced DNA sequencing and traditional microscopy, they confirmed this pathogen causes dark spots on mulberry leaves that reduce quality and yield, harming the silk industry that relies on mulberry leaves to feed silkworms. The study developed specific detection methods to help farmers identify and manage this disease in their orchards.

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

mycolabadmin

Researchers identified eight species of Colletotrichum fungi causing plant diseases in Thailand. They discovered two completely new species and found these fungi on 13 additional plant hosts previously unknown. Using DNA analysis, they confirmed the identity of each fungal species and documented their characteristics. This work helps farmers and scientists better identify and manage these damaging plant pathogens.

Exploring fungal pathogens to control the plant invasive Rubus niveus on Galapagos Island San Cristobal

mycolabadmin

Scientists in the Galapagos Islands are working to control an invasive raspberry plant that is damaging the unique ecosystem. They identified five types of fungi that naturally attack this invasive plant and could potentially be used as a biological control method. These fungi were isolated from diseased raspberry plants and tested in the laboratory, showing promise as a sustainable alternative to expensive manual removal and chemical herbicides.

Plant Pathogenic Fungi Special Issue: Genetics and Genomics

mycolabadmin

This scientific review discusses how modern genetics and genomics tools are helping researchers better understand and manage plant diseases caused by fungi. Seven research studies are presented covering topics like identifying different fungal species, understanding how fungi attack plants, and finding natural alternatives to chemical fungicides. The research emphasizes the importance of monitoring fungal diseases and developing crops that resist infection to protect global food production.
