Soil polluted system shapes endophytic fungi communities associated with Arundo donax: a field experiment

mycolabadmin

Mining activities pollute soils with heavy metals and red mud waste, damaging ecosystems and making plant growth difficult. This study examined fungi living inside the roots of Arundo donax, a hardy plant that survives in polluted soils, grown in three soil types: clean, heavy metal-contaminated, and red mud-contaminated. The researchers found that fungal communities changed based on the type of pollution, with a fungus called Pleosporales sp. thriving in red mud and showing promise for helping clean up contaminated soils. This research suggests that understanding these beneficial fungi could improve strategies for using plants to remediate polluted environments.

Pathogen Identification, Antagonistic Microbe Screening, and Biocontrol Strategies for Aconitum carmichaelii Root Rot

mycolabadmin

Aconitum carmichaelii is a traditional Chinese medicinal plant that has become increasingly prone to root rot disease due to continuous farming in Yunnan. Researchers identified multiple disease-causing pathogens and discovered that beneficial bacteria called Bacillus can both fight these pathogens and improve plant health. One particularly effective strain enhanced soil quality and increased the plant’s natural defenses, achieving over 50% disease control without chemical pesticides.

Changes in the Arbuscular Mycorrhizal Fungal Community in the Roots of Eucalyptus grandis Plantations at Different Ages in Southern Jiangxi, China

mycolabadmin

This research examines how fungal partnerships with eucalyptus tree roots change as plantations age. Scientists found that two dominant fungal types, Paraglomus and Glomus, shift in abundance depending on the plantation age and soil nutrient levels. The study reveals that proper fertilization timing and understanding fungal communities can help improve plantation management and tree productivity in nutrient-poor soils.

Effects of Long-Term Heavy Metal Pollution on Microbial Community Structure in Soil

mycolabadmin

Heavy metals from mining operations contaminate farmland soil and reduce its quality. This research examined how different types of bacteria and fungi adapt to living in heavily polluted soil by collecting samples from a contaminated farm in China. The study found that specific microorganism species thrive in different levels of contamination and could potentially be used to help clean up polluted soils through natural biological processes.

Effects of Spent Mushroom Substrate Treated with Plant Growth-Promoting Rhizobacteria on Blueberry Growth and Soil Quality

mycolabadmin

This study shows that mushroom farming waste (spent mushroom substrate) can be recycled into a beneficial fertilizer by treating it with beneficial bacteria called plant growth-promoting rhizobacteria. When this treated waste is used to grow blueberries, the plants grow better with higher survival rates and produce more chlorophyll. The treatment also improves soil quality by making nutrients more available to plants and changing the beneficial microorganism community in the soil.

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.

Apple replant disease: unraveling the fungal enigma hidden in the rhizosphere

mycolabadmin

Apple orchards that are replanted in the same location often develop a disease that stunts growth and can kill young trees. Scientists discovered that harmful fungi, especially Fusarium species, grow excessively in the soil around diseased trees. These harmful fungi appear to be the main culprits behind the disease. The study identified specific fungicides that can control these pathogenic fungi, offering hope for preventing the disease in future plantings.

Exploring the Core Functional Microbiota Related to Flavor Compounds in Douchi from the Sichuan–Chongqing Region

mycolabadmin

Douchi is a traditional Chinese fermented soybean product valued for its unique flavor. This research examined seven different douchi samples to understand which bacteria and fungi create the flavor compounds. The scientists found that specific microorganisms like Bacillus and Mucor produce different flavor molecules including fruity, floral, and caramel aromas. These findings can help producers select the best microorganisms to create better-tasting douchi products.

Synergistic effects of beneficial microbial inoculants and SMS-amendments on improving soil properties and Pinus seedling growth in degraded soils

mycolabadmin

This study shows how mixing beneficial bacteria with mushroom waste can improve poor soil quality. The bacteria help break down the mushroom waste into nutrients that plants need, while also creating a healthier soil environment full of beneficial microbes. When this treated mushroom waste was added to degraded soil and used to grow pine seedlings, the plants grew taller with thicker stems and more leaves than in untreated soil. This approach offers a practical way to recycle agricultural waste while restoring damaged soils.

Analysis of the Differences in Rhizosphere Microbial Communities and Pathogen Adaptability in Chili Root Rot Disease Between Continuous Cropping and Rotation Cropping Systems

mycolabadmin

Rotating crops (chili with cotton) instead of continuously planting chili improves soil health by increasing helpful bacteria like Bacillus and reducing harmful fungi like Fusarium that cause root rot disease. Researchers studied how different cropping systems change the mix of microorganisms in soil around plant roots and identified two main disease-causing fungi. This research shows that crop rotation is a natural, chemical-free way to prevent chili disease and maintain productive farmland.
