The role of the transcription factor FsBrlA in regulating sporulation, cell wall integrity stress response, and pathogenicity in Fusarium solani.

Deletion of FsbrlA in Fusarium solani results in a 93.9% reduction in spore production and a 96.4% decrease in spore germination rate, impairing sporulation.

• Why it matters: Understanding the role of FsbrlA is crucial because it influences fungal growth, development, and pathogenicity, which are key to managing fungal diseases caused by F. solani.
• What they did: The study used a split-marker homologous recombination strategy to create FsbrlA knockout and complementation strains, analyzing phenotypes, cell wall components, stress responses, and pathogenicity.
• The result: Loss of FsbrlA causes impaired sporulation, disrupted cell wall integrity, increased stress susceptibility, and reduced pathogenicity on wolfberry plants, highlighting its multifaceted biological role.
