Mycoviruses: Antagonistic Potential, Fungal Pathogenesis, and Their Interaction with Rhizoctonia solani

mycolabadmin

This comprehensive review explores how viruses that infect fungi, called mycoviruses, could help farmers control rice diseases. Rice sheath blight caused by the fungus Rhizoctonia solani causes significant crop losses worldwide. Scientists have discovered that certain mycoviruses can weaken this pathogenic fungus, making them promising biological alternatives to chemical fungicides that can harm the environment and encourage disease resistance.

Transmission of apple stem grooving virus (Capillovirus mali) to apple from the soil-borne fungus Fusarium solani

mycolabadmin

Researchers discovered that a common soil fungus called Fusarium solani can carry and transmit apple viruses to healthy apple trees through their roots. This fungus spreads the virus both to other fungal colonies and to apple plants, explaining how viruses naturally spread in apple orchards. This finding has important implications for protecting apple orchards and managing orchard soil health.

Fungal alkaloids mediate defense against bruchid beetles in field populations of an arborescent ipomoea

mycolabadmin

Morning glory trees (Ipomoea murucoides) form beneficial relationships with fungal partners that live inside their tissues and produce toxic compounds called alkaloids. These alkaloids accumulate in the tree’s seeds and protect them from beetle damage. Trees hosting the common fungal partner Ceramothyrium produce more of the protective alkaloid swainsonine and suffer less seed damage than those with a different fungal partner, demonstrating how this natural partnership helps the plant defend its offspring.

Transmission of apple stem grooving virus (Capillovirus mali) to apple from the soil-borne fungus Fusarium solani

mycolabadmin

Scientists discovered that a common soil fungus called Fusarium solani can catch and spread apple viruses to apple trees through their roots. This fungus naturally harbors the apple stem grooving virus and can pass it to healthy apple plants, causing reduced growth and damage to roots. The virus spreads within the fungus population both horizontally and vertically, suggesting fungi may be a previously unknown source of apple virus infection in orchards.
