Inbreeding Alters the Gut Microbiota of the Banna Minipig.

Project description:The gut microbiota coevolve with the host and can be stably transmitted to the offspring. Host genetics plays a crucial role in the composition and abundance of gut microbiota. Inbreeding can cause a decrease of the host's genetic diversity and the heterozygosity. In this study, we used 16S rRNA gene sequencing to compare the differences of gut microbiota between the Diannan small-ear pig and Banna minipig inbred, aiming to understand the impact of inbreeding on the gut microbiota. Three dominant bacteria (Stenotrophlomonas, Streptococcus, and Lactobacillus) were steadily enriched in both the Diannan small-ear pig and Banna minipig inbred. After inbreeding, the gut microbiota alpha diversity and some potential probiotics (Bifidobacterium, Tricibacter, Ruminocaccae, Christensenellaceae, etc.) were significantly decreased, while the pathogenic Klebsiella bacteria was significantly increased. In addition, the predicted metagenomic analysis (PICRUSt2) indicated that several amino acid metabolisms (''Valine, leucine, and isoleucine metabolism'', ''Phenylalanine, tyrosine, and tryptophan biosynthesis'', ''Histidine metabolism'') were also markedly decreased after the inbreeding. Altogether our data reveal that host inbreeding altered the composition and the predicted function of the gut microbiome, which provides some data for the gut microbiota during inbreeding.

Sus scrofa breed:Banna miniature inbred pig

Project description:Sus scrofa breed: A chromosome-scale reference genome of the Banna miniature inbred pig

| PRJNA1147459 | ENA

A chromosome-scale reference genome of the Banna miniature inbred pig.

Project description:The Banna miniature inbred pig (BN) is an intensively inbred line for biomedical research and xenotransplantation due to its low individual variation and stable genetic background. Although it is originated from the Diannan miniature pig (DN), substantial genetic changes have actually occurred. However, the lack of a BN reference genome has limited studies on the complete genomic architecture and utilization as a biomedical model. Here, we present a high-quality genome for BN using PacBio HiFi and Hi-C sequencing technologies, with a total length of 2.66 Gb, a scaffold N50 of 143.60 Mb, and 97.59% of the sequences anchored to chromosomes. Its BUSCO score is 96.30%, higher than porcine reference assembly and DN. The genome contains 48.49% of repeats, 19,756 protein-coding genes, and 7,207 non-coding RNAs according to our annotation. The OMArk score shows a proteome completeness and consistency of 99.58% and 93.62%, respectively. These findings indicate that the chromosome-scale genome of BN provides a valuable resource for studying the genetic basis of inbreeding, facilitating further research and clinical applications.

Candidate transcriptomic sources of inbreeding depression in Drosophila melanogaster

Project description:The genomic causes of inbreeding depression are poorly known. Several studies have found widespread transcriptomic alterations in inbred organisms, but it remains unclear which of these alterations are causes of the depression and which are mere responses to the ensuing physiological stress. We made a c-DNA microarray analysis in Drosophila melanogaster attempting to differentiate causes from responses of inbreeding depression. The rationale of the experiment was that, while depression is a general phenomenon producing similar consequences in different inbred lines, its first genetic causes would be different for each inbred line, as they are expected to be caused by the fixation of rare deleterious genes. Many changes in expression were common to all sets, but fourteen genes, grouped in four expression clusters, showed strong set-specific changes, and were therefore candidates to be sources of the inbreeding depression observed.

Porcine ovary tissues : Minipig ovary vs. Pig ovary

Project description:Successful production of offspring in mammals is determined by the growth and apoptosis pathway, which is responsible for maintaining the balance between the estrous cycle. It is also believed that the development of the porcine ovary is regulated similarly; however, the molecular mechanism underlying differences in follicle development in the minipig and pig has yet to be elucidated. The present study aimed to identify developmental-associated genes differentially expressed in the minipig vs. pig.
