The mushroom Coprinopsis cinerea is a classic experimental model for multicellular development in fungi because it grows on defined media, completes its life cycle 2 weeks, produces some 10 8 synchronized meiocytes, and can be manipulated at all stages by mutation transformation. 37-megabase genome of C. was sequenced assembled into 13 chromosomes. Meiotic recombination rates vary greatly along the chromosomes, retrotransposons are absent large regions with low levels meiotic recombination....

Background The human gut microbiota has profound influence on host metabolism and immunity. This study characterized the fecal in patients with nonalcoholic steatohepatitis (NASH). relationship between changes hepatic steatosis was also studied. Methods Fecal of histology-proven NASH healthy controls analyzed by 16S ribosomal RNA pyrosequencing. were from a previously reported randomized trial probiotic treatment. Proton-magnetic resonance spectroscopy performed to monitor intrahepatic...

Bacteria, archaea and fungi play crucial roles in wetland biogeochemical processes. However, little is known about their community structure, dynamics interactions subtropical coastal wetlands. Here, we examined communities of the three kingdoms mangrove mudflat sediments a using Ion Torrent amplicon sequencing co-occurrence network analysis. Bacterial, archaeal fungal comprised mainly members from phyla Proteobacteria Bacteroidetes, Bathyarchaeota Euryarchaeota, Ascomycota, respectively....

Background Tuberculosis (TB) remains a global threat in the 21st century. Traditional studies of disease are focused on single pathogen Mycobacterium tuberculosis. Recent have revealed associations some diseases with an imbalance microbial community. Characterization TB microbiota could allow better understanding disease. Methodology/Principal Findings Here, sputum infection was examined by using 16S rRNA pyrosequencing. A total 829,873 high-quality sequencing reads were generated from 22...

Abstract Background The transition from the vegetative mycelium to primordium during fruiting body development is most complex and critical developmental event in life cycle of many basidiomycete fungi. Understanding molecular mechanisms underlying this process has long been a goal research on basidiomycetes. Large scale assessment expressed transcriptomes these stages will facilitate generation more comprehensive picture mushroom process. In study, we coupled 5'-Serial Analysis Gene...

The "developmental hourglass" concept suggests that intermediate developmental stages are most resistant to evolutionary changes and differences between species arise through divergence later in development. This high conservation during middevelopment is illustrated by the "waist" of hourglass it represents a low probability change. Earlier molecular surveys both on animals plants have shown genes expressed at waist stage more ancient conserved their expression. existence such has not been...

The phylum Cnidaria represents a close outgroup to Bilateria and includes familiar animals including sea anemones, corals, hydroids, jellyfish. Here we report genome sequencing assembly for true jellyfish Sanderia malayensis Rhopilema esculentum. homeobox gene clusters are characterised by interdigitation of Hox, NK, Hox-like genes revealing an alternate pathway ANTP class dispersal intact three ParaHox cluster. mitochondrial genomes linear but, unlike in Hydra, do not detect nuclear copies,...

Abstract Whole genome duplication (WGD) has occurred in relatively few sexually reproducing invertebrates. Consequently, the WGD that common ancestor of horseshoe crabs ~135 million years ago provides a rare opportunity to decipher evolutionary consequences duplicated invertebrate genome. Here, we present high-quality assembly for mangrove crab Carcinoscorpius rotundicauda (1.7 Gb, N50 = 90.2 Mb, with 89.8% sequences anchored 16 pseudomolecules, 2 n 32), and resequenced tri-spine Tachypleus...

ABSTRACT The effect of different substrates and various developmental stages (mycelium growth, primordium appearance, fruiting-body formation) on laccase production in the edible mushroom Lentinula edodes was studied. cap mature showed highest activity, activity not stimulated by some well-known inducers or sawdust. For our molecular studies, two genomic DNA sequences, representing allelic variants L. lac1 gene, were isolated, sequence analysis demonstrated that encodes a putative...

As adulterated and substituted Chinese medicinal materials are common in the market, therapeutic effectiveness of such cannot be guaranteed. Identification at species-, strain- locality-levels, therefore, is required for quality assurance/control medicine. This review provides an informative introduction to DNA methods authentication materials. Technical features examples based on sequencing, hybridization polymerase chain reaction (PCR) described their suitability different identification...

Esophageal squamous cell carcinoma (ESCC) is the most common histological subtype of esophageal cancer worldwide. Patients with ESCC display an altered microbiota compared healthy individuals; however, little known about gut in ESCC.Here, we characterized fecal 15 patients and 16 control subjects using 16S rRNA gene sequencing.After controlling for potential confounders, significant alterations both taxonomic functional composition were observed. By contrast, alpha diversity did not...
