CWI-MAPKs Regulate the Formation of Hyphopodia Required for Virulence in Ceratocystis fimbriata

mycolabadmin

Black rot disease in sweet potatoes is caused by a fungus that uses specialized infection structures called hyphopodia to penetrate plant cells. This study reveals that a cellular signaling pathway involving specific proteins (MAPKs) controls the formation of these infection structures and regulates how the fungus spreads through plants. Understanding this mechanism could help develop new ways to prevent sweet potato infections.

Benzothiazole—An Antifungal Compound Derived from Medicinal Mushroom Ganoderma lucidum against Mango Anthracnose Pathogen Colletotrichum gloeosporioides

mycolabadmin

Scientists discovered that a chemical called benzothiazole found in the medicinal mushroom Ganoderma lucidum can effectively kill the fungus that causes mango anthracnose, a major disease affecting mango crops. The research showed that this natural compound completely stops fungal growth at very low concentrations (50 ppm) and prevents spore germination. This discovery offers a promising eco-friendly alternative to synthetic fungicides that can cause environmental pollution and drug resistance.

Bacterial community shifts in Fusarium-induced avocado root rot and the antagonistic potential of Bacillus siamensis NB92

mycolabadmin

Avocado plants are threatened by a fungal disease called root rot that damages roots and reduces fruit production. Researchers discovered that when avocado roots become diseased, the beneficial bacteria in the soil around the roots decrease significantly. They isolated a beneficial bacterium called Bacillus siamensis NB92 from healthy avocado soil that can fight against the disease-causing fungus by producing special compounds. When applied to diseased soil, this bacterium reduced the fungal pathogen and protected avocado stems from damage, offering a natural alternative to chemical treatments.

Genome analysis of Phytophthora cactorum strains associated with crown- and leather-rot in strawberry

mycolabadmin

Strawberry farmers face two serious diseases caused by a water-mold pathogen: crown rot that kills the whole plant and leather rot that spoils the fruit. Scientists sequenced the DNA of different disease-causing strains to understand why some strains can infect only fruit while others destroy the entire plant. They found that highly virulent strains have specific genetic changes in genes that help the pathogen escape the plant’s immune system, which could help develop better disease control strategies.

Control effects and mechanisms of metabolites from Streptomyces ahygroscopicus var. gongzhulingensis strain 769 on sclerotinia rot in sunflowers

mycolabadmin

Scientists discovered that a beneficial soil bacterium called Streptomyces can effectively control sunflower rot disease caused by a harmful fungus. When applied to soil or roots, this bacterium reduced disease severity by over 50% and improved plant root health and seed quality. The treatment works by both directly killing the pathogenic fungus and strengthening the plant’s natural defense systems.

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

mycolabadmin

Scientists studied two species of fungi called Arachnopeziza that are closely related to powdery mildew fungi but can grow independently on simple lab media. By analyzing their complete genomes and developing techniques to genetically modify these fungi, researchers created a new tool for understanding how powdery mildew fungi became dependent on plants. This breakthrough allows scientists to study these harmful plant pathogens more effectively without having to work directly with the difficult-to-cultivate powdery mildew fungi.

Inhibition of Fusarium oxysporum growth in banana by silver nanoparticles: In vitro and in vivo assays

mycolabadmin

Bananas are threatened by a fungal disease called Fusarium wilt that damages crops worldwide. Scientists tested tiny silver particles called nanoparticles as a treatment for this disease on banana plants. The treatment successfully reduced disease by about 68% when applied to the roots, showing promise as an alternative to traditional fungicides for protecting banana crops.

Inhibition of Fusarium oxysporum growth in banana by silver nanoparticles: In vitro and in vivo assays

mycolabadmin

Researchers tested silver nanoparticles as a potential cure for Fusarium wilt, a serious fungal disease that damages banana crops worldwide. Using laboratory tests and greenhouse experiments with banana plants, they found that silver nanoparticles effectively killed the fungus and reduced disease symptoms by about 68% when applied to plant roots. The study shows that this nanotechnology approach could offer a new way to protect banana plantations from this devastating disease.

An Efficient Microwave Synthesis of 3-Acyl-5-bromoindole Derivatives for Controlling Monilinia fructicola and Botrytis cinerea

mycolabadmin

Scientists developed new chemical compounds called indole derivatives that can kill harmful fungi that destroy fruit crops like stone fruits and grapes. These compounds were made using microwave heating, which is faster and more efficient than traditional methods. Testing showed that some of these new compounds were even better at fighting these fungal diseases than current commercial fungicides, offering promise for protecting crops in agriculture.

Inhibitory Effects and Mechanisms of Perilla Essential Oil and Perillaldehyde against Chestnut Pathogen Botryosphaeria dothidea

mycolabadmin

Chestnut rot caused by the fungus Botryosphaeria dothidea is a major problem during fruit storage. Researchers found that essential oil from perilla plants and its main component perillaldehyde effectively kill this fungus by damaging its cell walls and membranes. This natural solution could replace harmful synthetic fungicides while keeping chestnuts fresh longer during storage.
