Disease: plant pathogenic infections

Three novel species of Cladosporium and Sarocladium isolated from palm trees

Researchers in China discovered three new species of fungi growing on palm tree leaves. These fungi, belonging to the genera Cladosporium and Sarocladium, were identified using genetic testing and microscopic examination. The findings help scientists better understand fungal diversity on ornamental plants and may assist in managing fungal diseases that affect palm trees cultivated in gardens and landscapes.

The fungal STRIPAK complex: Cellular conductor orchestrating growth and pathogenicity

The STRIPAK complex is a cellular control hub found in fungi that acts like a conductor orchestrating multiple cellular processes essential for fungal growth and the ability to cause disease. Scientists have discovered that this complex is highly conserved across different fungal species and regulates critical virulence factors like melanin production and capsule formation in pathogenic fungi. Because the fungal version differs from the human version, it presents a promising target for developing selective antifungal medications. Understanding how STRIPAK works provides insights into how fungi cause infections and could lead to new treatment strategies.

Polyamine Induction of Secondary Metabolite Biosynthetic Genes in Fungi Is Mediated by Global Regulator LaeA and α-NAC Transcriptional Coactivator: Connection to Epigenetic Modification of Histones

Polyamines are natural compounds that act like chemical switches controlling how fungi produce useful medicines like antibiotics and statins. These molecules work by attaching to DNA and modifying histone proteins, which turns on or off the genes responsible for making pharmaceutical compounds. This research reveals that understanding polyamine control could help scientists increase antibiotic production and make plants more resistant to fungal diseases.
