Egg production performance a critical economic trait in the poultry industry. The regulatory mechanisms underlying egg production performance mediated by non-coding RNAs remain to be characterized. To systematically investigate ovarian lncRNAs, circRNAs, and miRNAs associated with laying efficiency, we conducted comparative transcriptomic analyses using RNA sequencing (RNA-seq) of ovarian tissues from phenotypically divergent groups - high egg production (HEP) and low egg production (LEP) hens.

Integrating whole-genome re-sequencing and transcriptome data to reveal the molecular mechanism of TBX5 gene regulating feathered feet in Guangxi native chickens.

Feathered foot is a trait observed in domestic and wild chickens, resulting from the partial or complete transformation of scales on the tarsus, shanks, and toes into feathers. Although previous studies have mapped genomic loci associated with feathered feet, the molecular mechanisms underlying this transformation remain unclear. This study combined whole-genome re-sequencing (WGS) data, transcriptomic analysis, and cellular experiments to investigate the genetic basis of feathered feet in Guangxi native chickens.

High Muscle Expression of IGF2BP1 Gene Promotes Proliferation and Differentiation of Chicken Primary Myoblasts: Results of Transcriptome Analysis.

Muscle development is a multifaceted process influenced by numerous genes and regulatory networks. Currently, the regulatory network of chicken muscle development remains incompletely elucidated, and its molecular genetic mechanisms require further investigation. The Longsheng-Feng chicken, one of the elite local breeds in Guangxi, serves as an excellent resource for the selection and breeding of high-quality broiler chickens.

The sperm storage capacity in hens was correlated with the morphological differences of the oviduct and uterus-vagina junction.

The fertilization rate is an important index to evaluate the reproductive capacity of hens, which is mainly affected by semen quality, timing of artificial insemination (AI), and the ability to store sperm. A high sperm storage (SS) capacity can extend the interval, reduce the frequency, and decrease the labor costs of AI. However, relatively few studies have investigated the SS capacity of hens.

Identification of genes associated with sperm storage capacity in hens at different times after insemination by RNA-seq and Ribo-seq.

Background: Sperm storage capacity (SSC) determines the duration of fertility in hens and is an important reproduction trait that cannot be ignored in production. Currently, the genetic mechanism of SSC is still unclear in hens. Therefore, to explore the genetic basis of SSC, we analyzed the uterus-vagina junction (UVJ) of hens with different SSC at different times after insemination by RNA-seq and Ribo-seq.

The order was divided into eight suborders. However, the phylogenetic relationships among some suborders are largely unresolved, and the phylogenetic positions and delimitations of some taxa, such as and , remain unsettled. In this study, sequence data of 38 genomes were generated through genome skimming on an Illumina sequencing system.

Four New Species and One New Record of from China.

Species of the genus (Thelephorales, Thelephoraceae) are ectomycorrhizal symbionts of coniferous and broad-leaved plants, and some of them are well-known edible mushrooms, making it an exceptionally important group ecologically and economically. However, the diversity of the species from China has not been fully elucidated.

Molecular phylogenetics of the Ophiocordyceps sinensis-species complex lineage (Ascomycota, Hypocreales), with the discovery of new species and predictions of species distribution.

Ophiocordyceps sinensis is a famous traditional Chinese medicine adapted to the alpine environment of the Qinghai-Tibet Plateau and adjacent regions. Clarification of the species diversity of Ophiocordyceps sinensis and its relatives could expand the traditional medicinal resources and provide insights into the speciation and adaptation. The study is prompted by the discovery of a new species, O.

Stable functional structure despite high taxonomic variability across fungal communities in soils of old-growth montane forests.

Background: Major advances over the past decade in molecular ecology are providing access to soil fungal diversity in forest ecosystems worldwide, but the diverse functions and metabolic capabilities of this microbial community remain largely elusive. We conducted a field survey in montane old-growth broadleaved and conifer forests, to investigate the relationship between soil fungal diversity and functional genetic traits. To assess the extent to which variation in community composition was associated with dominant tree species (oak, spruce, and fir) and environmental variations in the old-growth forests in the Jade Dragon Snow Mountain in Yunnan Province, we applied rDNA metabarcoding.

Transcriptome profiling analysis of uterus during chicken laying periods.

The avian eggshell is formed in the uterus. Changes in uterine function may have a significant effect on eggshell quality. To identify the vital genes impacting uterine functional maintenance in the chicken, uteri in three different periods (22W, 31W, 51W) were selected for RNA sequencing and bioinformatics analysis.

Identification of genes involved in regulating the development of feathered feet in chicken embryo.

The genetic and developmental factors driving the diverse distribution and morphogenesis of feathers and scales on bird feet are yet unclear. Within a single species, Guangxi domestic chickens exhibit dramatic variety in feathered feet, making them an accessible model for research into the molecular basis of variations in skin appendages. In this study, we used H&E staining to observe the morphogenesis of feathered feet, scaled feet and wings skin at different embryonic stages in Longsheng-Feng chickens and Guangxi Partridge chickens.

Phylogeny, Taxonomy and Evolutionary Trade-Offs in Reproductive Traits of Gomphoid Fungi (Gomphaceae, Gomphales).

Although functional ecology is a well-established field, our understanding of the evolutionary and ecological significance of the reproductive traits in macrofungi is still limited. Here, we reconstructed a phylogeny tree of gomphoid fungi in the narrower sense, including the species of the genera and and used it to uncover the evolution of reproductive traits. Our analyses indicated that fungal fruit bodies and spores did not enlarge at a steady rate over time.

Phylogeny and Taxonomic Revision of the Family (, ).

Species of are common macrofungi with a worldwide distribution. Some of them are commercially consumed, while a few others are reported as poisonous. Two genera were accepted in the family: the epigeous Gyromitra with discoid, cerebriform to saddle-shaped ascomata and the hypogeous Hydnotrya with globose or tuberous ascomata.

During follicular development, a series of key events such as follicular recruitment and selection are crucially governed by strict complex regulation. However, its molecular mechanisms remain obscure. To identify the dominant genes controlling chicken follicular development, the small white follicle (SWF), the small yellow follicle (SYF), and the large yellow follicle (LYF) in different laying stages (W22, W31, W51) were collected for RNA sequencing and bioinformatics analysis.

The genus and species are proposed as new based on morphological assessments and molecular phylogenetic evidence inferred from nucleotide sequences of mitochondrial (mt) adenosine triphosphate (ATPase) subunit 6 () and mt small subunit rDNA (mtSSU). Basidiomes of are characterized by the peach to pinkish orange color, cantharelloid habit with a gill-like hymenophore with obtuse edges, smooth and cylindrical to allantoid basidiospores, and cylindrical to narrowly clavate flexuous pleurocystidia. The species resembles a species of but differs from the latter by the cylindrical basidiospores.

Evolutionary innovations through gain and loss of genes in the ectomycorrhizal Boletales.

We aimed to identify genomic traits of transitions to ectomycorrhizal ecology within the Boletales by comparing the genomes of 21 symbiotrophic species with their saprotrophic brown-rot relatives. Gene duplication rate is constant along the backbone of Boletales phylogeny with large loss events in several lineages, while gene family expansion sharply increased in the late Miocene, mostly in the Boletaceae. Ectomycorrhizal Boletales have a reduced set of plant cell-wall-degrading enzymes (PCWDEs) compared with their brown-rot relatives.

Transcriptome analysis reveals key genes and pathways associated with egg production in Nandan-Yao domestic chicken.
