  • Question: Metatranscriptome binning

    Hi Everyone!

    We work with a lignocellulose-degrading microbial consortia. Within a time-series experiment of an enriched culture, we perform a de novo crossassembly of metatranscriptome reads of four samples using SPAdes assembler and DIAMOND annotation, prior to differential expression analysis, we estimate the metabolic contribution of the individuals by recruitment of few bacterial genomes, surprisevely, there was five genomes almost totally covered by the RNA-seq data! and we decide try to perform a binning (MetaBAT) whit this data. One of the bins reached a 98% of completeness. It should be noted that RNA samples was treated with DNAse and RiboZero.
    In your opionion, what could be the source of the sequences that contributed to these results? Is the effect by the algorithm more likely than some biological event difficult to circumvent such as the separation of operons in a non-synchronous culture?

    Thanks a lot

    Hi,
    I guess that the number of transcripts for that particular bacteria are more that they could cover 98% of their respective genome. If you do not expect this maybe you need to change the binning parameters.
    Good luck!

      Essential Discoveries and Tools in Epitranscriptomics
      by seqadmin




      The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
