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.

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.

Safe and Effective Antioxidant: The Biological Mechanism and Potential Pathways of Ergothioneine in the Skin

mycolabadmin

Ergothioneine is a natural compound found in certain fungi and bacteria that acts like a powerful antioxidant in the body. When applied to skin, it can protect against damage from sun exposure and environmental pollution, reduce signs of aging, and help calm inflammation. It’s particularly special because it automatically travels to damaged areas in the skin where it’s needed most, making it an efficient and targeted treatment ingredient for cosmetics.
