Supplemental Table4. Enriched samples, however, had enough reads to align samples to SC1, SC2 and JXGC3 prophage reference sequences. To confirm the expected library size of approximately 550bp, pooled libraries were run on either an Agilent Bioanalyzer or TapeStation (Agilent, Santa Clara, CA). Draft Genome Sequence of Candidatus Liberibacter asiaticus from a Citrus Tree in San Gabriel, California. By re-optimizing the pooling strategy for the tailed primers, we demonstrate that this tailed amplicon approach can achieve similar coverage to the untailed ARTIC v3 primers at equivalent sequencing depths.

This approach has the disadvantage that samples must typically be sequenced very deeply in order to obtain sufficient coverage of the viral genome, and thus the cost of this approach is high relative to more targeted methods.

Probable Pangolin Origin of SARS-CoV-2 Associated with the COVID-19 Outbreak. Ct values were exported and analyzed in Microsoft Excel. 14, 178192 (2013). For samples with Ct values between 30 and 35, coverage metrics tended to be less robust at a given read depth and samples with Ct values of greater than 35 did not perform well under any of the conditions tested. PDF Agilent RNA ScreenTape Assay Quick Guide for 4200 TapeStation System 20, 1239 (2012). Such genomic surveillance has already enabled insights into the origin and spread of SARS-CoV-2 [7, 8], including the sequencing efforts by the Seattle flu study which provided early evidence of extensive undetected community transmission of SARS-CoV-2 in the Seattle area [9]. 3 and TableS4).

Alignment files were filtered to remove PCR duplicates, retaining only reads in proper pairs with robust mapping quality (MAPQ10) using Samtools v. 1.728. Given the small genome size, the ability to sequence SARS-CoV-2 at scale is limited by the cost and labor associated with making sequencing libraries. Hundreds of millions of sequencing reads are needed to get good coverage of CLas from an HLB positive citrus sample.

Not surprisingly, we got the same prophage pattern for the SGCA strain sequenced in this study as SGCA5 (SC1 only), another strain from the same location14. Since primers cannot capture the very ends of the viral genome, amplicon approaches have the drawback of slightly less complete genome coverage, and mutations in primer binding sites have the potential to disrupt the amplification of the associated amplicon [12]. How to Export Agilent TapeStation Logs Several variants of the ARTIC protocol exist in which the pooled SARS-CoV-2 amplicons from a sample are taken through a NGS library preparation protocol (using either ligation or tagmentation-based approaches) in which sample-specific barcodes are added, and are then sequenced using either short-read (Illumina) or long-read (Oxford Nanopore, PacBio) technologies. Gnirke, A. et al. Int J Med Microbiol. The number in each circle represents the number of SNPs between the different comparisons. With positive target selection, the probe-bound DNA is eluted and collected for further NGS application, and often has much higher target DNA concentration than the original input samples19,20. b In the ARTIC protocol, first strand cDNA is enriched by amplifying with two pools of primers to generate amplicons tiling the SARS-CoV-2 genome.

Hundreds of millions of sequencing reads are needed to get good CLas genome coverage from an infected citrus sample, making CLas genome sequencing challenging and costly18. Nearly all draft genomes come from highly infected citrus or psyllids (usually with a Cq value lower than 23 using Li 16S qPCR), which limits strain diversity and epidemiology studies since not all samples can be sequenced reliably. We quantify and determine the integrity of your RNA or DNA prior to downstream applications such as library preparation. The tailed amplicon method we describe represents a cost-effective and highly scalable method for SARS-CoV-2 sequencing. Samples with N1 and N2 Ct values ranging from approximately 2040 chosen for testing of SARS-CoV-2 sequencing workflows.

For target selection, pre-designed probes are added to the mixed genomic DNA extracts and capture their complimentary DNA sequences through complimentary hybridization, allowing the uncaptured DNA to be removed during wash steps. We anticipate that this approach will aid in the genomic surveillance of SARS-CoV-2 as well as studies on viral diversity and evolution, and the influence of virus genetics on transmissibility, virulence, and clinical outcomes. The Agilent TapeStation system is an automated electrophoresis solution for the sample quality control of DNA and RNA samples. An estimated 10,000 viral genome copies were used as input for cDNA generation. To determine the prophage content of each sample, we aligned all the reads from enriched samples to SC1, SC2 and JXGC3 prophage reference sequences using bowtie2 plugged in Geneious v 10.2.425, and visualized alignments in Integrated Genome Viewer v2.4.1026,27.

Based on validation experiments for the University of Minnesota qRT-PCR clinical COVID-19 diagnostic assay, we estimate that a Ct value of 30 corresponds to roughly 500 SARS-CoV-2 genome copies and a Ct value of 35 corresponds to roughly 15 SARS-CoV-2 genome copies in the 5L input used for cDNA creation [18]. Interested in learning more about the TapeStation systems and how easy-to-use ScreenTape technology can give you a faster time to results and constant per-sample costs in sample quality control? 2a-b, Supplemental Tables12). Agilent has a new system that fills the same space as the BioAnalyzer but is reportedly simpler and faster. For each CLas samples, gray graphs represent read coverage in log scale. A total of 100ng of amplicons from the ARTIC protocol were used as the input for library preparation. a In Illuminas Nextera DNA Flex Enrichment protocol cDNA is tagmented and made into barcoded sequencing libraries, which are then enriched using sequence capture with a respiratory virus panel containing probes against SARS-CoV-2. The most divergent region of the CLas genome is the prophage region, where strains can contain one to three prophages, with three prophage types known to date.
