FoCup, a secreted protein, is essential for virulence of Fusarium oxysporum f. sp. cucumerinum on cucumber

mycolabadmin

Researchers identified a key protein called FoCup that helps a fungal pathogen infect cucumber plants and cause devastating wilt disease. By deleting this protein from the fungus, scientists significantly reduced its ability to cause disease and produce spores needed for spreading. This discovery could help develop new ways to protect cucumber crops by targeting this critical virulence factor.

FONPS6, a Nonribosomal Peptide Synthetase, Plays a Crucial Role in Achieving the Full Virulence Potential of the Vascular Wilt Pathogen Fusarium oxysporum f. sp. Niveum

This research explores how a specific fungal gene called FoNPS6 helps the watermelon-wilt-causing fungus Fusarium oxysporum attack plants. Scientists deleted this gene and found that mutant fungi were much less aggressive, couldn’t handle stress well, and struggled to penetrate plant roots. When the gene was restored, the fungi regained full virulence. The study reveals that FoNPS6 helps the fungus absorb iron and break down plant defense chemicals.

Genetic and Genomic Analysis Identifies bcltf1 as the Transcription Factor Coding Gene Mutated in Field Isolate Bc116, Deficient in Light Responses, Differentiation and Pathogenicity in Botrytis cinerea

mycolabadmin

Scientists discovered that a particular gray mold fungus collected from vineyards loses its ability to cause disease when exposed to light. They found this is due to a mutation in a single gene called bcltf1, which acts as a light-sensing control switch. When they restored this gene, the fungus regained its disease-causing ability. This discovery helps explain how fungal pathogens sense light and use it to decide when and how to infect plants.
