Antifungal activities of Rosmarinus extracts against Fusarium oxysporum, the pathogenic fungus of Anoectochilus stem rot

mycolabadmin

Researchers found that extracts from rosemary plants can effectively fight a fungus that causes stem rot disease in Anoectochilus, a valuable medicinal herb. The rosemary extracts worked both in laboratory tests and when applied to infected plants, reducing disease symptoms and boosting the plant’s natural defense mechanisms. These findings suggest rosemary extracts could be developed as a natural, safer alternative to synthetic chemical fungicides that harm the environment.

FoCup, a secreted protein, is essential for virulence of Fusarium oxysporum f. sp. cucumerinum on cucumber

mycolabadmin

Researchers identified a key protein called FoCup that helps a fungal pathogen infect cucumber plants and cause devastating wilt disease. By deleting this protein from the fungus, scientists significantly reduced its ability to cause disease and produce spores needed for spreading. This discovery could help develop new ways to protect cucumber crops by targeting this critical virulence factor.

Morphological, molecular, and biological characterization of bulb rot pathogens in stored Lanzhou lily and the in vitro antifungal efficacy of three plant essential oils

mycolabadmin

Lanzhou lily is a valuable medicinal and food plant that loses 20-25% of its crop annually due to fungal rot during storage. Researchers identified the main culprit as a fungus called Fusarium oxysporum and found that natural essential oils from cinnamon, tea tree, and angelica plants can effectively inhibit this fungus’s growth. Cinnamon essential oil proved most effective and could serve as a natural alternative to chemical fungicides for protecting stored lily bulbs.

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.

Histological Dissection of Fusarium-Banana Interaction Using a GFP-Tagged Subtropical Race 4 Strain of Fusarium oxysporum f. sp. cubense on Banana Cultivars with Differing Levels of Resistance

mycolabadmin

Researchers used fluorescently-labeled fungal strains to visualize how banana wilt disease spreads inside banana plants. They found that resistant banana varieties can slow down the fungus by forming blockages (called tyloses) in their water-conducting vessels, though the fungus can still initially enter the plant. The study showed that the rhizome, an underground stem-like structure, is the key location where resistant plants successfully contain the fungus, which helps explain why some banana varieties are naturally more resistant to this devastating disease.

Successful Treatment of Fungal Dermatitis in a Bottlenose Dolphin (Tursiops truncatus)

mycolabadmin

A bottlenose dolphin at a Japanese aquarium developed a serious fungal infection on its tail fin while suffering from severe digestive problems and weight loss. The infection was caused by two types of fungi that are normally hard to treat because they resist many antifungal medications. Veterinarians successfully treated the dolphin using a combination of two antifungal drugs (voriconazole and terbinafine), surgical removal of dead tissue, and daily wound cleaning with special solutions. The dolphin’s wound eventually healed completely, and this is the first documented successful treatment of these particular fungal infections in bottlenose dolphins.

Esterase and Peroxidase Are Involved in the Transformation of Chitosan Films by the Fungus Fusarium oxysporum Schltdl. IBPPM 543

mycolabadmin

Scientists discovered that a fungus called Fusarium oxysporum can safely modify chitosan films (a material made from shellfish shells) without breaking them apart. Instead of using destructive enzymes, the fungus produces special enzymes called esterase and peroxidase that reorganize the chitosan’s structure, making it stronger and more resistant. This discovery could lead to new medical materials, drug delivery systems, and water purification products with customized properties.

Cell wall remodeling in a fungal pathogen is required for hyphal growth into microspaces

mycolabadmin

Researchers discovered how fungi squeeze through tiny spaces inside plant tissues to cause disease. They found that fungi need to soften and remodel their cell walls to reduce their width and fit through spaces that are much narrower than normal fungal filaments. This ability to change shape is critical for the fungus to invade and colonize plants, ultimately causing wilting diseases in crops like tomatoes.

Complete mitochondrial genome of the fungal pathogen Fusarium oxysporum f. sp. palmarum responsible for fusarium wilt of palms

mycolabadmin

Scientists have decoded the complete genetic instruction manual for a fungus that causes a deadly disease in palm trees. The fungus, Fusarium oxysporum f. sp. palmarum, kills palm trees by causing one-sided leaf death that spreads upward through the canopy. By sequencing the fungus’s mitochondrial genome—the energy-producing part of its cells—researchers have created a tool that can help quickly and accurately identify this pathogen in infected plants. This discovery will help nurseries and gardeners detect and prevent the spread of this destructive disease.

Study of the Herbicidal Potential and Infestation Mechanism of Fusarium oxysporum JZ-5 on Six Broadleaved Weeds

mycolabadmin

Scientists discovered a fungal strain that effectively kills common broadleaved weeds found in farms on China’s Qinghai Plateau. The fungus, Fusarium oxysporum JZ-5, was particularly effective against henbit deadnettle and other problematic weeds while being safe for important crops like wheat, barley, and potatoes. This natural solution could replace harmful chemical herbicides and provide farmers with an environmentally friendly way to control weeds.
