Globally, the prevalence of obesity has increased, which has had severe detrimental effects on physical health in recent years. Several hypotheses explain the causes of obesity. The change in people’s eating habits is one significant reason, with high-fat diets (HFD) being of particular concern. Research has indicated that the gut…

Microbial community profiling using 16S rRNA amplicon sequencing allows for taxonomic characterization of diverse microorganisms.

Abstract The two most commonly used approaches to study the composition of environmental protist communities are marker gene metabarcoding and whole genome analysis through metagenomics. Raw metabarcoding data are usually processed into Operational Taxonomic Units (OTUs) or amplicon sequence variants (ASVs) through clustering or denoising approaches, respectively. Analogous approaches have…

All measurements and observations on animals were carried in accordance with ARRIVE guidelines and with the current law on animal experimentation and ethics, and approved by the French Ministry of Agriculture (authorization number: HC-69-2014-1) after evaluation by the Animal Care and Use Committee of French West Indies and Guyana (Comité…

Myxococcota and Bdellovibrionota were active constituents of activated sludge microbiota To explore the predating activity and diversity of predatory bacteria in activated sludge, 13C-labeled Escherichia coli and Pseudomonas putida cells (determined as 97.09 and 97.30 atom% 13C, respectively) were added to the sludge microcosms for maximumly eight days of incubation,…

Published: 9 February 2023| Version 1 | DOI: 10.17632/d4kb7zy533.1 Contributor: Lei Zhang Description Objectives: Exploring the bronchial bacterial microbiota of infants with recurrent wheezing that differ from foreign body aspiration controls, and the recurrent wheezing infants with atopy that differ from that without atopy to reveal the interactions between recurrent…

Hello everyone!We got data from 16s sequencing.I performed analysis with qiime2, then tried to use R for further analysis. So, I have created phyloseq object with next code:metadata<-read_q2metadata(“/path/metadata.tsv”, header = TRUE)features<-read_qza(“/path/table.qza”)taxonomy<-read_qza(“/path/taxonomy.qza”) taxonomy<-parse_taxonomy(taxonomy$data)head(taxonomy)phyloseq2<-qza_to_phyloseq(features = “/path/table.qza”,tree = “/path/rooted-tree.qza”,metadata = ” /path/metadata.tsv”,taxonomy = “/path/taxonomy.qza”)taxonomy = as.matrix(taxonomy) I got: phyloseqphyloseq-class experiment-level objectotu_table() OTU Table:…

I am using QIIME2 and R packages for microbiome analysis.I think QIIME2 is the best tool, especially for researchers who are about to begin the microbiome analysis. My question is about the decontamination process. I have the fastq files of 16s microbiome sequences from skin tissue samples. The sequence files…

Classification of snow algae in the ice core based on ITS2 sequences We used high-throughput sequencing to obtain DNA sequences of algae from 19 layers of an ice core drilled on a glacier in central Asia, dated from present time to 8000 years ago (Fig. 1 and Table S1). In total, 17,016…

Dear mothur enthusiasts, A colleague advised me to try and run picrust on my dataset in order to get some functional inference from 16S sequences. He told me to “classify the OTU on GreenGenes” and prepare a biom file. I have tried to follow the commands listed in an earlier…

Changes of straw degradation characteristics at different culture stages Corn straw degradation ratio Corn straw weight loss in M44 at F1 reached 35.90% at 15 ℃ for 21 days, which was greater than that at F5, F8, and F11 by 2.33%, 3.01%, and 3.35%, respectively. There were no significant differences between…

How to make alpha diversity boxplot? 1 How to make alpha diversity boxplot? I am trying to perform alpha diversity and I performed scatter plot for shannon measure,How can I make boxplot?? meta.physeq = sample_data(meta) tax <- otu_table(tax,taxa_are_rows=FALSE) physeq.alpha = phyloseq(ASV, tax, meta.physeq) sample_data(physeq.alpha)$shannon.physeq <- estimate_richness(physeq.alpha, measures=”Shannon”) plot_richness(physeq.alpha, measures=”Shannon”) alpha_diversity…

GWAS identifies genetic variations associated with agronomic traits in foxtail millet A total of 827 foxtail millet cultivars collected from China were sequenced and genotyped using common single-nucleotide polymorphisms (SNPs) based on a ~423 Mb Setaria italica cv. Zhanggu reference genome (v.2.3)27. In total, 161,562 SNPs were detected after stringent steps…

I am trying to create a taxonomic reference for some 16S/18S data in R and have been running into issues when following this tutorial. I am trying to create an OTU table from a taxonomy/sequence table that was bootstrapped for only 18S data. Here is the error I receive and…
