Molecular and Biological Characterization of an Isolate of Fusarium graminearum dsRNA mycovirus 4 (FgV4) from a New Host Fusarium pseudograminearum

Scientists discovered a virus that infects the fungus responsible for wheat crown rot disease. When this virus infects the fungus, it slows down the fungus’s growth and reduces its ability to cause disease in wheat plants. This finding suggests the virus could potentially be used as a natural biological control method to protect wheat crops from crown rot disease, offering an environmentally friendly alternative to chemical fungicides.

Novel endornaviruses infecting Phytophthora cactorum that attenuate vegetative growth, promote sporangia formation and confer hypervirulence to the host oomycete

Researchers discovered two new viruses infecting a plant-damaging organism called Phytophthora cactorum. When these viruses are present, the organism grows more slowly but becomes more aggressive at infecting plants. The viruses attach to special membranes inside cells and depend on cholesterol-like compounds for their replication. Scientists were able to remove the viruses from infected strains using specialized techniques, allowing them to compare infected and virus-free versions of the organism.
