Mycelial dynamics in arbuscular mycorrhizal fungi

mycolabadmin

This review examines the intricate underground networks formed by arbuscular mycorrhizal fungi, which partner with most land plants to help them absorb nutrients from soil. These fungal networks are far more complex and dynamic than previously recognized, expanding through the soil in coordinated wave-like patterns and responding flexibly to changing environmental conditions. The research highlights that viewing these fungal networks as a unified, responsive system rather than separate parts can help us better understand how they support plant growth and maintain healthy ecosystems.

A mycovirus enhances fitness of an insect pathogenic fungus and potentially modulates virulence through interactions between viral and host proteins

mycolabadmin

Scientists discovered a virus that infects a beneficial fungus used to control insect pests. Instead of harming the fungus, this virus makes it much better at its job by doubling spore production, helping it survive harsh conditions like UV radiation and heat, and making it more deadly to target insects. The improvement comes from specific interactions between viral and fungal proteins that work together to enhance the fungus’s natural pest-killing abilities.
