Project description:While DNA methylation in other tissues can be approximated through model species, the dynamic distribution and regulatory significance of DNA methylation in the rumen, a unique organ in ruminant, remain largely unknown. Here, we employed whole-genome bisulfite sequencing (WGBS), transcriptomics, and histone modification data to compare fetal and adult stages of bovine rumen with other tissues, including pluripotent stem cells (PSCs) approximating pre-implantation embryos. We found extensive methylation differences, including CG methylation (mCG) and non-CG methylation (mCH; H represents A, C and T) between the rumen at fetal and adult stages and other tissues and PSCs. These differentially methylated regions (DMRs) are closely associated with other epigenetic regulatory components, such as transcription factors (TFs) and histone modifications. These DMRs can also combine to form large hypo CG-DMRs to regulate a cluster of functionally related genes. We elucidated the reasons for morphological and functional differences between fetal and adult rumen at the epigenetic level and the interactions between epigenetic modifications and gene expression. This study highlights the differences in methylation patterns between the rumen and other tissues during development and the role of DNA methylation in controlling gene expression and establishing tissue-specific functions.

Project description:Protozoa comprise a major fraction of the microbial biomass in the rumen microbiome, of which the genera Entodinium has been consistently observed to be dominant across a diverse genetic and geographical range of ruminant hosts. Despite the apparent core role that species such as Entodinium caudatum exert, their greater biological and metabolic contributions to rumen function remain largely undescribed. Here, we have leveraged (meta)genome-centric metaproteome datasets from rumen fluid samples originating from both cows and goats fed contrasting diets, to detail the specific metabolic niches that E. caudatum occupies in the context of its bacterial and archaeal co-habitants. Initial proteome estimations via total protein counts and label free quantification highlight that E. caudatum populations comprise an extensive fraction of the total rumen metaproteome. Our analysis also suggested increased microbial predation and volatile fatty acid metabolism by E. caudatum to occur in high methane emitting animals, although with no apparent direct metabolic link to methanogenesis. Despite E. caudatum having a well-established reputation of digesting starch, it was unexpectedly less active in low methane emitting animals fed high starch diets, which were instead dominated by propionate/succinate-producing bacterial populations suspected of being resistant to predation. Collectively, our results illuminate the substantial metabolic influence under-explored eukaryotic populations have in the rumen, with greater implications towards both digestion and methane metabolism.

Abstract:
The rumen represents the first section of a ruminant
animal's stomach, where feed is collected and mixed with
microorganisms for initial digestion. The major gas produced in
the rumen is CO(2) (65.5 mol%), yet the metabolic
characteristics of capnophilic (CO(2)-loving) microorganisms
are not well understood. Here we report the 2,314,078 base pair
genome sequence of Mannheimia succiniciproducens MBEL55E, a
recently isolated capnophilic Gram-negative bacterium from
bovine rumen, and analyze its genome contents and metabolic
characteristics. The metabolism of M. succiniciproducens was
found to be well adapted to the oxygen-free rumen by using
fumarate as a major electron acceptor. Genome-scale metabolic
flux analysis indicated that CO(2) is important for the
carboxylation of phosphoenolpyruvate to oxaloacetate, which is
converted to succinic acid by the reductive tricarboxylic acid
cycle and menaquinone systems. This characteristic metabolism
allows highly efficient production of succinic acid, an
important four-carbon industrial chemical.
