    WGS prep of micro Eukaryotes

    We are planning to sequence a denovo reference genome of a micro Eukaryote, but cannot extract enough DNA from a single individual for PacBio or Nextera Illumina protocols. We have extracted DNA from 68 individuals of a single population and get 3.56ng total (100ul of 35.6pg/ul). We plan to pool these individuals for a "composite" genome. Our concerns include: 1) are they all the same species/lineage? 2) how useful is a ref genome generated from a composite of individuals? and 3) what will the assembly challenges be with the likely high rate of variation in reads?
    We have not seen many publications on this topic. Is anyone aware of publications on such a project or have any thoughts on this?
    thanks,

    Hi wbsimey,

    as mentioned in the other post I also would recommend to work with a single cell in this case (I assume a single individual can not propagate) and amplify the sample by whole genome amplification before library prep (MDA).
    Fro prokaryotes this has been done frequently.

      Thank you Luc. When you say "as mentioned in the other post ..." which post are you referring to? Do you have a reference/protocol for whole genome amplification? Can this be done on a multicellular organism rather than a single cell?

        16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
        by SEQadmin2




        NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
