The dynamic changes of rumen bacterial and fungal microbiota in free-ranged Gangba plateau sheep

Abstract Gangba sheep is an important sheep breed in Xizang plateau; however, little information is available about its rumen microbiota. This study revealed the composition and characteristics of rumen bacterial and fungal microbiota in free-ranged Gangba sheep. For bacterial an...

Dose-Dependent Preservation of Highland Barley Flour Storage Quality by Lycium barbarum Polysaccharide: Evidence from 240-Day Storage Monitoring and Untargeted Lipidomics

Highland barley (hulless barley, Hordeum vulgare L. var. nudum) flour is a nutritionally dense staple of the Qinghai–Tibet Plateau, but its high contents of unsaturated lipids and active endogenous enzymes render it highly susceptible to storage deterioration. Natural polysacchar...

Whole-genome resequencing reveals genetic diversity, population structure, and selection signatures in tibetan yak

The Tibetan yak is a keystone species in the Tibetan Plateau ecosystem. It serves as a vital source of livelihood for local herders and also represents a distinctive model for studying biological adaptation mechanisms to extreme high-altitude environments. The Xizang region harbo...

Integrated analysis of mRNA and lncRNA transcriptomes in peripheral blood of Holstein cattle at high and low altitudes

Holstein cattle are selected for high milk yield but show limited adaptation to hypoxic environments. The transcriptional features underlying their long-term response to hypoxic stress, particularly the role of non-coding RNAs, remain poorly understood. This study analysed mRNA a...

Population structure and signatures of selection in Horpa sheep

Abstract Horpa sheep, an indigenous sheep breed native to the high-altitude regions of the Xizang Autonomous Region in China, are characterized by distinctive adaptive and economic traits. Whole-genome resequencing and comparative analyses of different sheep populations have been...

Early Compound Nutritional Intervention Improves Hair Follicle Development in Northwest Xizang White Cashmere Goats: An Analysis Based on Skin Multi-Omics

The Northwest Xizang White Cashmere goat has a high global reputation for good goat cashmere germplasm characteristics, and its cashmere industry is the economic pillar of the herdsmen in the northwest plateau of Xizang. Cashmere is produced by the secondary hair follicles of the...

Partner of bursicon Regulates Pheromone Gland Development and Sex Pheromone Biosynthesis in Helicoverpa armigera

Bursicon, a heterodimeric neuropeptide composed of Burs-α and its binding subunit Partner of bursicon (Pburs), is primarily known to regulate insect cuticle tanning and also participates in wing expansion, reproduction and immunity. Pburs is highly expressed during pheromone glan...

Genome-wide identification and systematic characterization of MATH family genes and expression analysis of response to abiotic stresses in Brassica napus L

Abstract Background Meprin and TRAF-C homology (MATH) proteins function as adaptor molecules and components of E3 ubiquitin ligase complexes. They link receptor-like kinase signalling to downstream regulatory pathways in plants. MATH proteins coordinate growth, hormone signalling...

Visual and rapid detection of Fasciola spp. in fecal samples using a one-pot RPA-CRISPR/Cas12a assay

Fasciolosis caused by Fasciola spp. has substantial veterinary and public-health importance, while conventional fecal microscopy has limited sensitivity and PCR depends on laboratory equipment. This study aimed to develop a rapid, visual one-pot recombinase polymerase amplificati...

Regulatory Role of Adrenomedullin in Hypoxic Adaptation of Yak Subcutaneous Preadipocytes

High-altitude hypoxic environments constrain yaks’ survival capacity and metabolic adaptability. Subcutaneous adipose tissue helps yaks withstand cold and resist hypoxic stress, and ADM participates in cellular stress and metabolic regulation. To explore the regulatory role of AD...

Effects of dietary supplementation with Enterococcus faecalis JM263 on growth performance, antioxidant status, rumen microbiota and metabolism in yaks

Yaks are vital to the ecology and economy of the Qinghai-Xizang Plateau. The unique environmental conditions of this high-altitude region have shaped yaks, leading to significant differences in their evolution from other cattle species. From yak gut contents, we isolated Enteroco...
