The Structural and Functional Diversities of Bacteria Inhabiting Plant Woody Tissues and Their Interactions with Fungi

mycolabadmin

Bacteria living in tree wood work together with fungi to break down wood and nutrients, which is important for forest health. Some bacteria can protect trees from harmful fungi by fighting them off, making them useful for controlling plant diseases. Understanding how bacteria and fungi interact in wood can help us grow healthier plants, manage tree diseases better, and improve wood decomposition processes.

Chemical profile and bioactivity of essential oils from five Turkish thyme species against white mold fungal disease agent Sclerotinia sclerotiorum

mycolabadmin

Researchers studied five types of Turkish thyme plants to see if their essential oils could fight a harmful fungus called Sclerotinia sclerotiorum that damages crops like cucumbers and sunflowers. They found that thyme oils, especially those rich in carvacrol and thymol, were very effective at stopping fungal growth. These natural plant oils could be used as safer alternatives to chemical fungicides in farming, reducing environmental damage while controlling plant diseases.

Circadian clock is critical for fungal pathogenesis by regulating zinc starvation response and secondary metabolism

mycolabadmin

Scientists discovered that Fusarium oxysporum, a fungus that causes plant diseases, uses an internal clock system to time its attacks on plants. The fungus is most dangerous at dawn, when it activates special genes to survive the plant’s defenses and produce toxins. By disrupting the fungus’s clock genes, researchers found they could make it harmless. This discovery could lead to new ways to protect crops by targeting the pathogen’s timing system rather than using traditional fungicides.

Isolation and identification of antagonistic fungi for biocontrol of Impatiens hawkeri leaf spot disease and their growth-promoting potential

mycolabadmin

Researchers discovered a beneficial fungus called Fusarium solani that prevents leaf spot disease in ornamental Impatiens hawkeri plants. This fungus not only fights the disease-causing pathogen but also promotes seed germination and plant growth. The findings suggest this fungus could replace harmful chemical pesticides while simultaneously acting as a natural fertilizer, benefiting both plant health and the environment.

First Report of Trametes hirsuta, Causal Agent White Rot in Avocado Trees Grown in the State of Michoacán, México

mycolabadmin

Scientists in Mexico discovered a wood-rotting fungus called Trametes hirsuta infecting avocado trees for the first time. The fungus causes white rot disease that damages tree wood and can kill trees within 3-5 years. Researchers found the fungus on 60% of avocado trees in Michoacán orchards and confirmed its destructive effects through laboratory tests. Treatment options include pruning infected areas and applying antifungal chemicals or biological control agents.
