Regulation of Oomycete Autophagy, Lipid Droplet Accumulation and Pathogenesis by Three Rab GTPases

mycolabadmin

This research investigates three protein molecules called Rab GTPases that control important cellular processes in a disease-causing organism called Peronophythora litchii, which damages litchi fruit crops. Scientists used modern gene-editing technology to remove these proteins and discovered they regulate how the pathogen grows, reproduces through spores, handles stress, and causes disease. The findings suggest these Rab proteins could be targeted to develop new strategies for controlling litchi downy blight and related plant diseases.

Management of Green Mold Disease in White Button Mushroom (Agaricus bisporus) and Its Yield Improvement

mycolabadmin

Green mold is a serious problem for farmers growing white button mushrooms, often destroying entire crops. This research tested various fungicide treatments to find the most effective ways to control the mold while keeping the mushrooms healthy and productive. The study found that certain chemicals like captan and carbendazim work best at specific concentrations, allowing farmers to get better harvests while protecting their crops.

Rice varietal intercropping mediates resistance to rice blast (Magnaporthe oryzae) through core root exudates

mycolabadmin

Growing different varieties of rice together can help protect susceptible rice plants from blast disease. When resistant and susceptible rice varieties are planted together, the resistant plants release special chemicals from their roots that help the susceptible plants fight off the fungal disease. Scientists identified four key chemicals—azelaic acid, sebacic acid, betaine, and phenyl acetate—that work together to boost the immune system of susceptible rice plants and directly kill the blast fungus.

The Velvet Complex Is Essential for Sclerotia Formation and Virulence in Sclerotinia sclerotiorum

mycolabadmin

Scientists studied a destructive fungus that damages crops by identifying key genes controlling its ability to form protective resting structures called sclerotia and cause disease. Using genetic screening techniques, they discovered that two genes called SsLae1 and SsVel1 work together as master controllers of both the fungus’s survival and its ability to infect plants. These findings could help develop new ways to control the disease by targeting these critical genes.

In Vitro and Field Effectiveness of the Combination of Four Trichoderma spp. Against Sclerotinia sclerotiorum and Its Impact on Potato (Solanum tuberosum L.) Crop Production

mycolabadmin

This study tested whether four types of beneficial fungi (Trichoderma species) could control white mold disease on potato plants in Mexico. Both laboratory tests and field trials showed these fungi were very effective at killing the disease pathogen and stopping mold formation. Potatoes treated with the fungal mixture produced higher yields than those treated with chemical fungicides alone, suggesting this natural approach could replace many chemical pesticides.

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.

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.

Whole-genome sequencing of Fusarium oxysporum K326-S isolated from tobacco

mycolabadmin

Scientists have sequenced the complete genetic code of a fungus called Fusarium oxysporum that infects tobacco plant roots, causing them to wilt and turn brown. This fungus is a major problem for tobacco farmers because it lives in soil and is difficult to control. By mapping out all 17,272 genes in this fungus, researchers now have detailed information that will help them develop better ways to prevent and manage this disease.

Development of Green Fluorescent Protein-Tagged Strains of Fusarium acuminatum via PEG-Mediated Genetic Transformation

mycolabadmin

Scientists developed a method to genetically modify a harmful fungus called Fusarium acuminatum that causes root rot in plants like carnations. Using a technique that breaks down the fungal cell wall and uses a special chemical (PEG) to insert genes, they successfully added a green-glowing protein (GFP) marker to the fungus. This allows researchers to track where and how the fungus infects plants. The modified fungus still behaves normally, making it a useful tool for identifying which genes make the fungus dangerous, potentially leading to better disease control methods.

Tracking of Tobacco Mosaic Virus in Taxonomically Different Plant Fungi

mycolabadmin

Scientists discovered that a common plant virus (tobacco mosaic virus) can infect and multiply inside certain fungal pathogens that harm crops. When the virus enters these fungi, the fungi activate their natural defense system to fight back. Interestingly, the virus doesn’t make the fungi more or less dangerous to plants. This discovery opens new possibilities for controlling harmful fungi using viruses as biological tools.
