Article Abstract
sect. consists of telamonioid species with violet basidioma, strong odor, and distinct cheilocystidia. In this study, phylogenetic analysis based on nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS) and partial nuc rDNA 28S sequences has revealed three new species of the section from southwestern China, namely, , and , and a newly recorded species from southwestern China, viz., , supplemented by the support from calculations of genetic distances of ITS sequences. Detailed descriptions of the four species are given with photographs, and their micromorphological characteristics are statistically compared. For species delimitation within the section, the size of basidiospores, the morphology of cheilocystidia, and the associated vegetation types and tree species are informative. A key to species in section from the Northern Hemisphere is provided, and their geographic distributions and ecology are discussed.

The emergence of antimicrobial resistance poses significant challenges in conventional antibiotic treatments for chronic wound infections, highlighting an urgent need for alternative therapeutic strategies. To address this issue, we developed a multifunctional electrospun nanofiber dressing co-loaded with anthocyanin (ATH) and asiaticoside (AS) that possesses antimicrobial activity. The tri-layer dressing contains three functional components: a hydrophilic polyacrylonitrile-anthocyanin (PAN-ATH) layer for pH monitoring, a hydrophobic polycaprolactone (PCL) layer for exudate management, and a water-soluble pullulan-Bletilla striata polysaccharide-asiaticoside (PUL-BSP-AS) layer.

Myelination is essential for normal brain function, yet the mechanisms governing neuron-oligodendrocyte interactions that ensure proper myelination levels remain poorly understood. Here, we identify transcription factor EB (TFEB) as a molecular link that connects extrinsic neuronal cues to intrinsic oligodendrocyte transcriptional programs, regulating central nervous system myelination. Using a TFEB epitope-tagged knock-in mouse model, we find that neurons sequester most of the TFEB protein in the cytoplasm of myelinating oligodendrocytes.

Wound healing is often hindered by bacterial infection, oxidative stress, and bleeding. Traditional dressings cannot simultaneously regulate multiple microenvironments. To address the shortcomings of traditional dressings, this study constructed a dual-network photothermal responsive multifunctional hydrogel OBCTCu based on four natural ingredients, including Bletilla striata polysaccharide (BSP), chitosan (CS), tannic acid (TA), and Cu.

The expansion of floriculture has increased the need for sustainable floral waste management to support agricultural carbon neutrality. This study assessed the impact of carnation, lily, and rose straw amendments (with varying C/N ratios, lignin, and cellulose) on GHG emissions and soil quality with earthworm (Eisenia fetida). Controlled microcosm experiments were conducted to examine the effects of straw types and earthworms on CO and NO fluxes, as well as soil properties, enzyme activities, and microbial functions.
