Your Weekly Dose of Mycology Research
Ophiocordyceps zhenxingensis, a newly identified insect-pathogenic fungus from Liaoning, China, shows distinct microbiota compositions across its reproductive stages. The study reveals greater microbial diversity and complexity during its asexual stage, primarily involving Proteobacteria and Ascomycota, providing insights into its developmental biology and taxonomy.
Trichoderma aggressivum, a notorious agent of green mold disease in Agaricus bisporus, also holds potential as a biocontrol agent and plant growth promoter. This study provides a comprehensive genomic engineering toolkit for T. aggressivum, detailing transformation protocols and CRISPR-Cas9-based genome editing, leveraging hph and pyr4 selection markers for efficient research applications.
Ganoderma lucidum polysaccharide (G-GLP) and carboxymethyl chitosan hydrogels are bioactive compounds noted for their therapeutic properties. Recent research highlights G-GLP's efficacy in modulating macrophage polarization, thereby accelerating wound healing. In vivo studies reveal its significant role in reducing inflammation, enhancing blood vessel repair, and promoting collagen deposition, suggesting its promise as a wound repair dressing.
In mycology, unspecific peroxygenases (UPOs) are fungal enzymes known for their ability to catalyze selective hydroxylation reactions. A recent study highlights the engineered A77L variant of Agrocybe aegerita UPO, which achieved 92% enantioselectivity for the (S)-19-hydroxyarachidonic acid, showcasing its potential as a biocatalyst for pharmaceuticals.
