Summary: In this study, a novel double-stranded RNA mycovirus named Cordyceps chanhua alternavirus 1 (CcAV1) was discovered and characterized in the entomogenous fungus Cordyceps chanhua in China. The complete genome of CcAV1 consists of three segments encoding a putative RNA-dependent RNA polymerase and two hypothetical proteins. Phylogenetic analysis suggests that CcAV1 belongs to the proposed family Alternaviridae.

Summary: Intravenous immunoglobulin (IVIg) has been investigated as a potential treatment for radiation injuries. The results showed that IVIg can protect against radiation-induced hematopoietic and gastrointestinal toxicity in female mice but not in males. In addition, IVIg can modulate gut microbiota configurations in both females and males. Overall, IVIg shows potential as a sex-specific therapeutic avenue to improve the prognosis of cancer patients undergoing radiotherapy.

Summary: The Ca2+/calmodulin-dependent signaling pathway plays critical roles in regulating growth, conidiation, and stress response in nematode-trapping fungi. The deletion of the Crz1 gene (DdaCrz1) in Drechslerella dactyloides significantly reduced hyphal growth and trap formation, and altered sensitivity to various ions and stress conditions. This study highlights the importance of the Ca2+/calmodulin-dependent signaling pathway in trapping nematodes.

Summary: Four new 9,11-secosteroid-derived gamma-lactones, called Altersteroids A-D (1-4), were isolated from a culture of the ascomycete fungus Alternaria sp. Their structures were determined primarily by NMR experiments. The absolute configuration of compound 1 was established through X-ray crystallographic analysis, while the configurations of compounds 2-4 were assigned using quantum-chemical calculations. These compounds feature a gamma-lactone moiety fused to the steroid D ring at C13/C-14. Compound 3 exhibited moderate cytotoxicity against four tumor cell lines and induced apoptosis in A549 cells. Notably, compound 3 showed equipotent activity against cisplatin-sensitive and cisplatin-resistant MB49 cells, with an IC50 value of 12.7 μM.

Summary: During a field survey, two causal agents of mushroom diseases - Diploospora longispora and Paecilomyces penicillatus - were identified, causing up to 80% of yield losses. Phylogenetic analysis revealed that these fungi belong to a distinct clade in Hypocreales. Two new genera, Pseudodiploospora and Zelopaecilomyces, were introduced based on their morphological characteristics and phylogenetic relationships. Five new combinations were proposed.

Summary: Calcium ion (Ca2+) serves as a universal second messenger in regulating various processes in animals, plants, and fungi. The low-affinity calcium uptake system (LACS) is responsible for acquiring Ca2+ from the extracellular environment under high extracellular Ca2+ concentration. Nematode-trapping fungi (NTF) encode two related proteins for LACS, and this study focused on characterizing the role of DhFIG_2, an ortholog of AoFIG_2, in growth and development of Dactylellina haptotyla. Knocking down the expression of DhFIG_2 via RNA interference (RNAi) significantly impacted conidiation, trap formation, vegetative growth, and stress responses, indicating the importance of this LACS component in NTF.

Summary: A high-performance liquid chromatography (HPLC) method using one reference compound was developed for the determination of 4 nucleosides in Chinese cordyceps. The method involved ultrasonic extraction of the cordyceps sample with a 0.5% phosphoric acid solution, followed by separation on a CORTECS T3 column using acetonitrile and water as the mobile phase. The established HPLC method showed good accuracy, precision, reproducibility, and stability, making it suitable for the quantitative analysis of nucleosides in Chinese cordyceps. The method is a simple, cost-effective, and time-saving alternative for quality control of Chinese cordyceps.
