Exploring fungal pathogens to control the plant invasive Rubus niveus on Galapagos Island San Cristobal

mycolabadmin

Hill raspberry is a highly invasive plant that has taken over approximately 30,000 hectares of the Galapagos Islands, threatening native plant species. Traditional control methods like manual removal and herbicide spraying are expensive and ineffective. Researchers identified five species of fungal pathogens that naturally occur on infected Hill raspberry plants and can cause disease on healthy plants, offering promise as biological control agents to suppress this invasive species.

Integrated genome and transcriptome analysis reveals pathogenic mechanisms of Calonectria eucalypti in Eucalyptus leaf blight

mycolabadmin

Scientists studied a dangerous fungus called Calonectria eucalypti that kills eucalyptus trees worldwide. They sequenced the fungus’s entire genetic code and tracked which genes it turned on during infection. They found that the fungus uses different strategies at different stages of infection, starting with penetration, then breaking down plant cell walls, and finally stealing nutrients. This research helps us understand how the fungus works and develop better ways to protect eucalyptus plantations.

Integrated genome and transcriptome analysis reveals pathogenic mechanisms of Calonectria eucalypti in Eucalyptus leaf blight

mycolabadmin

This research examines a dangerous fungus called Calonectria eucalypti that destroys eucalyptus trees worldwide. Scientists sequenced the fungus’s complete genetic code and tracked which genes turn on during infection, discovering that the pathogen uses different sets of genes at different stages of infection. By identifying key virulence genes and understanding how the fungus attacks plant cells, this research provides a foundation for developing better ways to prevent and manage eucalyptus leaf blight disease.
