Project description:Members of the genus Hepacivirus have a broad range of hosts, with at least 14 species identified. To date, a highly pathogenic hepacivirus causing severe disease in animals has not been found. Here, by using high-throughput sequencing, a new hepacivirus was identified as the dominant and highly pathogenic virus in severe acute hepatitis outbreaks in bamboo rats (Rhizomys pruinosus), with ≈80% mortality; this virus emerged in February 2020 in two bamboo rat farms in China. Hepaciviral genome copies in bamboo rat liver were significantly higher than in other organs. Genomic sequences of hepacivirus strains from 12 sick bamboo rats were found to share 85.3 to 100% nucleotide (nt) identity and 94.9 to 100% amino acid (aa) identity and to share 79.7 to 87.8% nt and 90.4 to 97.8% aa identities with previously reported bamboo rat hepaciviruses of Vietnam and China. Sequence analysis further revealed the simultaneous circulation of genetically divergent hepacivirus variants within the two outbreaks. Phylogenetic analysis showed that hepacivirus strains from the present and previous studies formed an independent clade comprised of at least two genotypes, clearly different from all other known species, suggesting a novel species within the genus Hepacivirus. This is the first report of a non-human-infecting hepacivirus causing potentially fatal infection of bamboo rats, and the associated hepatitis in the animals potentially can be used to develop a surrogate model for the study of hepatitis C virus infection in humans and for the development of therapeutic strategies. IMPORTANCE Members of the genus Hepacivirus have a broad host range, with at least 14 species identified, but none is highly pathogenic to its host except for hepatitis C virus, which causes severe liver diseases in humans. In this study, a new liver-tropic hepacivirus species was identified by high-throughput sequencing as the pathogen associated with two outbreaks of severely acute hepatitis in hoary bamboo rats (Rhizomys pruinosus) on two farms in Hainan Province, China; this is the first reported highly pathogenic animal hepacivirus to our knowledge. Further phylogenetic analysis suggested that the hepaciviruses derived from hoary bamboo rats in either the current or previous studies represent a novel species within the genus Hepacivirus. This finding is a breakthrough that has significantly updated our understanding about the pathogenicity of animal hepaciviruses, and the hepacivirus-associated hepatitis in bamboo rats may have a use as an animal infection model to understand HCV infection and develop therapeutic strategies.

Project description:Moso bamboo (Phyllostachys edulis (Carrière) J. Houz.), ) is one of the most importantessential economic bamboo species in China. However, the woods quality and yield of bamboo shoots were significantly threatened by diverse environmental conditions. significantly threaten the quality of wood and yield of bamboo shoots. In this study, to explore the molecular mechanism of abiotic stress response, we report the RNA-seq analyses of mosoMoso bamboo treated with drought, salt, SA and ABA at three -time courses. A total of 224.4 Gb clean data were generate in to explore the molecular mechanism of the abiotic stress response. The full-length transcriptome sequencing of these four treatments generated a total of 224.4 Gb data after quality trimming, and approximately 5.83Gban average of 6.615 Gb clean data were per sample was generated in per sample. The comparative analyses of the generated transcriptome data in this study will provide a valuable resource for identifying regulatory genes and potential pathways involved in various abiotic stresses in mosoMoso bamboo.

Project description:<p>Bamboo rats (<em>Rhizomys pruinosus</em>) are among the few mammals that lives on a bamboo-based diet which is mainly composed of lignocellulose. However, the mechanisms of adaptation of their gut microbiome and metabolic systems in the degradation of lignocellulose are largely unknown. Here, we conducted a multi-omics analysis on bamboo rats to investigate the interaction between their gut microbiomes and metabolic systems in the pre- and post-weaning periods, and observed significant relationships between dietary types, gut microbiome, serum metabolome and host gene expression. For comparison, published gut microbial data from the famous bamboo-eating giant panda (<em>Ailuropoda melanoleuca</em>) were also used for analysis. We found that the adaptation of the gut microbiome of the bamboo rat to a lignocellulose diet is related to a member switch in the order Bacteroidales from family <em>Bacteroidaceae</em> to family <em>Muribaculaceae</em>, while for the famous bamboo-eating giant panda, several aerobes and facultative anaerobes increase after weaning. The conversion of bacteria with an increased relative abundance in bamboo rats after weaning enriched diverse carbohydrate-active enzymes (CAZymes) associated with lignocellulose degradation and functionally enhanced the biosynthesis of amino acids and B vitamins. Meanwhile, the circulating concentration of short chain fatty acids (SCFAs) derived metabolites and the metabolic capacity of linoleic acid in the host were significantly elevated. Our findings suggest that fatty acid metabolism, including linoleic acid and SCFAs, are the main energy sources for bamboo rats in response to the low-nutrient</p>

Project description:Bamboo represents the only major lineage of grasses that is native to forests and is one of the most important non-timber forest products in the world. Moso bamboo is a large woody bamboo that has ecological, economic and cultural value in Asia and accounts for ~70% of the total bamboo growth area (Peng et al., 2013). In the aspect of epigenetics of Moso bamboo,the total genomic DNA methylation rates in Moso bamboo at different chronological ages were significantly different (Yuan et al., 2014). Those show that the flowering of Moso bamboo are closely related to epigenetic modification. However, DNA methylation in single base resolution has never been reported in moso bamboo. In this study, leaves from three-week bamboo, one-year bamboo, flower in next year bamboo, flowering bamboo and Flower florets was used for bisulfite sequencing (BS-seq), and RNA-Seq. Genome-wide methylation profile and gene expression analysis were constructed to reveal the factors to regualte the phase transition from vegetative to reproductive growth in moso bamboo.
