Abstract
Fat storage and weight gain are dominant traits for hibernating mammals. However, excessive fat accumulation may cause liver damage. Here, we explore the lipid accumulation and metabolic processes of the Himalayan marmot (Marmota himalayana), a hibernating rodent species. We find that the unsaturated fatty acid (UFA) content in food was consistent with a large increase in the body mass of Himalayan marmots. Metagenomic analysis shows that Firmicutes Bacterium CAG:110 plays a synergistic role by synthesizing UFAs, which is demonstrated by fecal transplantation experiments, indicating that the gut microbiome promotes fat storage in Himalayan marmots for hibernation. Microscopic examination results indicate that the risk of fatty liver appears at maximum weight; however, liver function is not affected. Upregulations of UFA catabolism and insulin-like growth factor binding protein genes provide an entry point for avoiding liver injury.

Abstract
The Tibetan Partridge (Perdix hodgsoniae) is an endemic species distributed in high-altitude areas of 3600-5600 m on the Qinghai-Tibet Plateau. To explore how the species is adapted to the high elevation environment, we assembled a draft genome based on both the Illumina and PacBio sequencing platforms with its population genetics and genomics analysis. In total, 134.74 Gb short reads and 30.81 Gb long reads raw data were generated. The 1.05-Gb assembled genome had a contig N50 of 4.56 Mb, with 91.94% complete BUSCOs. The 17 457 genes were annotated, and 11.35% of the genome was composed of repeat sequences. The phylogenetic tree showed that P. hodgsoniae was located at the basal position of the clade, including Golden Pheasant (Chrysolophus pictus), Common Pheasant (Phasianus colchicus), and Mikado Pheasant (Syrmaticus mikado). We found that 1014, 2595, and 2732 of the 6641 one-to-one orthologous genes were under positive selection in P. hodgsoniae, detected using PAML, BUSTED, and aBSREL programs, respectively, of which 965 genes were common under positive selection with 3 different programs. Several positively selected genes and immunity pathways relevant to high-altitude adaptation were detected. Gene family evolution showed that 99 gene families experienced significant expansion events, while 6 gene families were under contraction. The total number of olfactory receptor genes was relatively low in P. hodgsoniae. Genomic data provide an important resource for a further study on the evolutionary history of P. hodgsoniae, which provides a new insight into its high-altitude adaptation mechanisms.

Enlarged fins of Tibetan catfish provide new evidence of adaptation to high plateau. SCIENCE CHINA. LIFE SCIENCES 2023:10.1007/s11427-022-2253-7. [PMID: 36802318 DOI: 10.1007/s11427-022-2253-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Accepted: 11/30/2022] [Indexed: 02/23/2023]
Abstract
The uplift of the Tibetan Plateau significantly altered the geomorphology and climate of the Euroasia by creating large mountains and rivers. Fishes are more likely to be affected relative to other organisms, as they are largely restricted to river systems. Faced with the rapidly flowing water in the Tibetan Plateau, a group of catfish has evolved greatly enlarged pectoral fins with more numbers of fin-rays to form an adhesive apparatus. However, the genetic basis of these adaptations in Tibetan catfishes remains elusive. In this study, we performed comparative genomic analyses based on the chromosome-level genome of Glyptosternum maculatum in family Sisoridae and detected some proteins with conspicuously high evolutionary rates in particular in genes involved in skeleton development, energy metabolism, and hypoxia response. We found that the hoxd12a gene evolved faster and a loss-of-function assay of hoxd12a supports a potential role for this gene in shaping the enlarged fins of these Tibetan catfishes. Other genes with amino acid replacements and signatures of positive selection included proteins involved in low temperature (TRMU) and hypoxia (VHL) responses. Functional assays reveal that the G. maculatumTRMU allele generates more mitochondrial ATP than the ancestral allele found in low-altitude fishes. Functional assays of VHL alleles suggest that the G. maculatum allele has lower transactivation activity than the low-altitude forms. These findings provide a window into the genomic underpinnings of physiological adaptations that permit G. maculatum to survive in the harsh environment of the Tibetan Himalayas that mirror those that are convergently found in other vertebrates such as humans.

Abstract
Pareuchiloglanis macrotrema is a glyptosternoid fish belonging to the Siluriform family and is endemic to the Qinghai-Tibet Plateau tributaries. P. macrotrema is an ideal model for studying the adaptive evolution of fish at high altitudes. P. macrotrema has two attaching livers connected to the main liver, a common feature in most Sisoridae fishes but is a special phenomenon relative to other vertebrates. Using RNA-Seq, 42 differentially expressed genes were found between the main liver and attaching liver, of which 31 were upregulated and 11 were downregulated in the main liver. The major differentially expressed genes between the main liver and attaching liver of P. macrotrema are related to metabolism, immunity, and digestive processes. Meanwhile, a comparative transcriptome analysis was carried out on P. macrotrema fish and six non-plateau Siluriformes fishes. We found 268 positively selected genes in P. macrotrema that are related to energy metabolism, immunity, and hypoxic responses. The findings of this study highlight the gene expression differences between the main liver and attaching livers of Sisoridae fishes and provide greater insight into the evolution of Tibetan fishes.

Insights into chromosomal evolution and sex determination of Pseudobagrus ussuriensis (Bagridae, Siluriformes) based on a chromosome-level genome. DNA Res 2022; 29:dsac028. [PMID: 35861402 PMCID: PMC9358014 DOI: 10.1093/dnares/dsac028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Accepted: 07/20/2022] [Indexed: 12/01/2022] Open
Abstract
Pseudobagrus ussuriensis is an aquaculture catfish with significant sexual dimorphism. In this study, a chromosome-level genome with a size of 741.97 Mb was assembled for female P. ussuriensis. A total of 26 chromosome-level contigs covering 97.34% of the whole-genome assembly were obtained with an N50 of 28.53 Mb and an L50 of 11. A total of 24,075 protein-coding genes were identified, with 91.54% (22,039) genes being functionally annotated. Based on the genome assembly, four chromosome evolution clusters of catfishes were identified and the formation process of P. ussuriensis chromosomes was predicted. A total of 55 sex-related quantitative trait loci (QTLs) with a phenotypic variance explained value of 100% were located on chromosome 8 (chr08). The QTLs and other previously identified sex-specific markers were located in a sex-determining region of 16.83 Mb (from 6.90 to 23.73 Mb) on chr08, which was predicted as the X chromosome. The sex-determining region comprised 554 genes, with 135 of which being differently expressed between males and females/pseudofemales, and 16 candidate sex-determining genes were screened out. The results of this study provided a useful chromosome-level genome for genetic, genomic and evolutionary studies of P. ussuriensis, and also be useful for further studies on sex-determination mechanism analysis and sex-control breeding of this fish.
