Betulinic Acid Delays Turnip Mosaic Virus Infection by Activating the Phytosulfokine Signalling Pathway in Nicotiana benthamiana

mycolabadmin

Researchers discovered that betulinic acid, a natural compound found in birch and eucalyptus trees, can slow down turnip mosaic virus infection in plants. The compound works by activating a plant hormone called phytosulfokine through special receptors on plant cells, which strengthens the plant’s natural defence against the virus. This finding suggests betulinic acid could become an environmentally friendly alternative to chemical pesticides for protecting vegetable crops from viral diseases.

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.

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

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.
