Abstract The hard tick, Ixodes ricinus , a main Lyme disease vector, harbors an intracellular bacterial endosymbiont. Midichloria mitochondrii is maternally inherited and resides in the mitochondria of I. oocytes, but consequences this endosymbiosis are not well understood. Here, we provide 3D images wild-type aposymbiotic oocytes generated with focused ion beam-scanning electron microscopy. Quantitative image analyses endosymbionts oocyte at different maturation stages show that populations...
Abstract The discordance between genome size and the complexity of eukaryotes can partly be attributed to differences in repeat density. Muller F element (∼5.2 Mb) is smallest chromosome Drosophila melanogaster, but it substantially larger (>18.7 D. ananassae. To identify major contributors expansion assess their impact, we improved sequence annotated genes a 1.4-Mb region ananassae element, 1.7-Mb from D for comparison. We find that transposons (particularly LTR LINE...
Exploring metagenomic contigs and "binning" them into metagenome-assembled genomes (MAGs) are essential for the delineation of functional evolutionary guilds within microbial communities. Despite advances in automated binning algorithms, their capabilities recovering MAGs with accuracy biological relevance so far limited. Researchers often find that human involvement is necessary to achieve representative results. This manual process however expertise demanding labor intensive, it deserves...
The dynamics of individual microbial populations and their gene functions in agricultural soils amended with biochar remain elusive but are important for a deeper understanding nutrient cycling carbon (C) sequestration. In this study, we coupled DNA stable isotope probing (SIP) shotgun metagenomics order to target the active community microcosms which contained soil collected from biochar-amended control plots under napiergrass cultivation. Our analyses revealed that was composed...
The Pastaza-Marañón Foreland Basin (PMFB) holds the most extensive tropical peatland area in South America. PMFB peatlands store ~7.07 Gt of organic carbon interacting with multiple microbial heterotrophic, methanogenic, and other aerobic/anaerobic respirations. Little is understood about contribution distinct community members inhabiting peatlands. Here, we studied metagenomes three geochemically spanning minerotrophic, mixed, ombrotrophic conditions. Using gene- genome-centric approaches,...
The decomposition of soil organic carbon within tropical peatlands is influenced by the functional composition microbial community. In this study, building upon our previous work, we recovered a total 28 metagenome-assembled genomes (MAGs) classified as Bathyarchaeia from Pastaza-Marañón Foreland Basin (PMFB) in Amazon. Using phylogenomic analyses, identified nine genus-level clades to have representatives PMFB, with four forming putative novel family ("
Abstract Exploring metagenomic contigs and “binning” them are essential for delineating functional evolutionary guilds within microbial communities. Despite available automated binners, researchers often find human involvement necessary to achieve representative results. We present BinaRena, an interactive graphic interface dedicated aiding operators explore via customizable visualization associate with bins based on various data types, including sequence metrics, coverage profiles,...
Abstract The Pastaza-Marañón Foreland Basin (PMFB) holds the most extensive tropical peatland area in South America. PMFB peatlands store 7.07 Gt of organic carbon interacting with multiple microbial heterotrophic, methanogenic, and other oxic/anoxic respirations. Little is understood about contribution distinct community members inhabiting peatlands. Here, we studied metagenomes three geochemically spanning minerotrophic, mixed, ombrotrophic conditions.
