Cathaya argyrophylla Chun et Kuang is a first-grade protected tree in China with significant conservation value. In June 2022, needle cast was observed in approximately 27 to 34% of C. argyrophylla (n=200, covering about 1 ha) at Dashahe National Nature Reserve (28.

The Indo-Burma biodiversity hotspot for ferns: Updated phylogeny, hidden diversity, and biogeography of the java fern genus (Polypodiaceae).

The Indo-Burma Biodiversity Hotspot is renowned for its rich biodiversity, including that of vascular plants. However, the fern diversity and its endemism in this hotspot have not been well understood and so far, the diversity of very few groups of ferns in this region has been explored using combined molecular and morphological approaches. Here, we updated the plastid phylogeny of the Java fern genus with 226 (115% increase of the latest sampling) samples across the distribution range, specifically those of three phylogenetically significant species, , .

Dryopteris×subdiffracta (Dryopteridaceae), a new natural hybrid fern from Guangxi, China.

A new natural hybrid fern, Dryopteris×subdiffracta (Dryopteridaceae), is reported from Guangxi, China. Molecular phylogenetic analysis based on DNA sequences from the low-copy nuclear marker and plastid genome revealed respectively that and are parents of the new hybrid, with as the maternal parent. Cytometric analysis of the nuclear DNA content indicated that might be a diploid hybrid.

Transcriptome Analyses of Liver Sinusoidal Endothelial Cells Reveal a Consistent List of Candidate Genes Associated with Endothelial Dysfunction and the Fibrosis Progression.

Liver fibrosis is an important step in the transformation of chronic liver disease into cirrhosis and liver cancer, and structural changes and functional disorders of liver sinusoidal endothelial cells (LSECs) are early events in the occurrence of liver fibrosis. Therefore, it is necessary to identify the key regulatory genes of endothelial dysfunction in the process of liver fibrosis to provide a reference for the diagnosis and treatment of liver fibrosis. In this study, we identified 230 common differentially expressed genes (Co-DEGs) by analyzing transcriptomic data of primary LSECs from three different liver fibrosis mouse models (carbon tetrachloride; choline-deficient, l-amino acid-defined diet; and nonalcoholic steatohepatitis).

First Report of Root Rot of caused by in China.

Cathaya argyrophylla [Chun & Kuang.] is an ancient relict plant and its embryonic development is similar to that of Pinus species. This has important scientific value for studying the phylogeny of Pinaceae (Wu et al.

Flexible, Permeable, and Recyclable Liquid-Metal-Based Transient Circuit Enables Contact/Noncontact Sensing for Wearable Human-Machine Interaction.

The past several years have witnessed a rapid development of intelligent wearable devices. However, despite the splendid advances, the creation of flexible human-machine interfaces that synchronously possess multiple sensing capabilities, wearability, accurate responsivity, sensitive detectivity, and fast recyclability remains a substantial challenge. Herein, a convenient yet robust strategy is reported to craft flexible transient circuits via stencil printing liquid metal conductor on the water-soluble electrospun film for human-machine interaction.

Selaginellawuyishanensis (sect. Tetragonostachyae, Selaginellaceae), a new species from East China and its phylogenetic position based on molecular data.

A new spikemoss species, , is described and illustrated based on materials collected from Fujian Province, East China. The new species can be distinguished from Koidzumi and P. S.

Bifunctional MOF Doped PEO Composite Electrolyte for Long-Life Cycle Solid Lithium Ion Battery.

A highly stable composite electrolyte was developed in this research to address the performance decline over time in a solid lithium ion battery (SLIB). It involved the synthesis of bifunctional MOF material (MOF-2) from two different functionalized UiO-66 materials containing carboxyl groups and amine groups, respectively, and the subsequent blending of PEO (polyethylene oxide) with the MOF-2 to form the novel composite solid electrolyte (PEO-MOF-2). The composite electrolytes showed higher ionic conductivity (5.

(Dryopteridaceae), a new species from Hunan, China.

, a new species growing on limestone in the Wulingshan Mountains, Hunan, China, is described and illustrated. This species is most similar to and on general morphological traits, such as the form of scales, rhizome and sori, but differs by the number of vascular bundles at the base of the petiole, length to width ratio of lamina, stalk length of basal pinnae, division of the lamina, apex form of the pinnule and habitat. Moreover, molecular phylogenetic analysis using the chloroplast L gene suggested that , as the sister group of , is a monophyletic clade.

The identity of , as a new synonym of (Dennstaedtiaceae), based on morphology and DNA barcoding and the new distribution.

Based on field observations and examinations of herbarium specimens (including type material), consulting the original literature and molecular phylogenetic analysis of the and sequences, it is concluded that is conspecific with and is here formally treated as a synonym of it. Additionally is reported with new distribution records in Guangdong, Guangxi and the Hainan Island of China, respectively.

Large-scale phylogenomic analysis resolves a backbone phylogeny in ferns.

Background: Ferns, originated about 360 million years ago, are the sister group of seed plants. Despite the remarkable progress in our understanding of fern phylogeny, with conflicting molecular evidence and different morphological interpretations, relationships among major fern lineages remain controversial.

Results: With the aim to obtain a robust fern phylogeny, we carried out a large-scale phylogenomic analysis using high-quality transcriptome sequencing data, which covered 69 fern species from 38 families and 11 orders.

Re-establishment of species from synonymies based on DNA barcoding and phylogenetic analysis using Diplopterygium simulans (Gleicheniaceae) as an example.

Because synonymy treatment traditionally relies on morphological judgments, it usually causes many problems in species delimitation and in the biodiversity catalogue. For example, Diplopterygium simulans, which belongs to the Gleicheniaceae family, has been considered to be synonymous with D. glaucum or D.
