Genome report: Genome sequence of 1S1, a transformable and highly regenerable diploid potato for use as a model for gene editing and genetic engineering
<p>Generation of a genomic resource for a readily transformable diploid potato would provide a resource for high throughput functional analysis in potato. The heterozygous <em>Solanum tuberosum</em> Group Phureja clone 1S1 has a high regeneration rate, self-fertility, desirable tuber traits and is amenable to <em>Agrobacterium</em>-mediated transformation. To create a contiguous genome assembly, a homozygous doubled monoploid of 1S1 (DM1S1) was sequenced using 44 Gbp of long reads generated from Oxford Nanopore Technologies (ONT), yielding a 736 Mb assembly that encoded 31,145 protein-coding genes. The final assembly for DM1S1 represents a nearly complete genic space, shown by the presence of 99.6% (C:99.5%[S:97.8%, D:1.7%],F:0.1%,M:0.4%,n:1614) of the Benchmarking Universal Single Copy Orthologs. Variant analysis with Illumina reads from 1S1 was used to deduce its alternate haplotype using the variant calling tools Strelka2 (v2.9.10), GATK's Haplotypecaller (v4.1.4.1), and Freebayes (v1.3.2). These variants were used to create consensus fasta sequences with the DM1S1 assembly using bcftools (v1.9.64).</p>

The influence of human genetic variation on Epstein-Barr virus sequence diversity
<p>This project is the first attempt to apply a "genome-to-genome" approach to investigate the impact of the host genetic pressure on the genome of a member of the <em>Herpesviridae</em> family. Namely, 285 pairs of human and EBV genomes were sequenced and multiple GWASes between human and EBV variations were performed. This repository contains the results of downstream analysis on the pathogen-side. The variant calling data was produced from read alignment using BWA mem using GATK HC, SNVer, VarScan2, BCFtools, freebayes and the intersection of the sets of variation from the first three.</p> <ul> <li><strong>The "covstats" files</strong> contains statistics about the read alignment.</li> <li><strong>The tarball SHCS_EBV_variant_call.tar.gz</strong> contains all compressed VCF files.</li> <li><strong>The tarball SHCS_EBV_variant_matrices_stats.tar.gz</strong> contains all matrices used as traits in the GWASes, as well as a variety of statistics.</li> </ul> <p>The pipeline used to generate this data is publically available here: <a href="https://gitlab.com/ezlab/vir_var_calling/">https://gitlab.com/ezlab/vir_var_calling/</a></p>
Data from: Intraspecific DNA contamination distorts subtle population structure in a marine fish: decontamination of herring samples before restriction-site associated (RAD) sequencing and its effects on population genetic statistics
Wild specimens are often collected in challenging field conditions, where samples may be contaminated with the DNA of conspecific individuals. This contamination can result in false genotype calls, which are difficult to detect, but may also cause inaccurate estimates of heterozygosity, allele frequencies, and genetic differentiation. Marine broadcast spawners are especially problematic, because population genetic differentiation is low and samples are often collected in bulk and sometimes from active spawning aggregations. Here, we used contaminated and clean Pacific herring (Clupea pallasi) samples to test (i) the efficacy of bleach decontamination, (ii) the effect of decontamination on RAD genotypes, and (iii) the consequences of contaminated samples on population genetic analyses. We collected fin tissue samples from actively spawning (and thus contaminated) wild herring and non-spawning (uncontaminated) herring. Samples were soaked for 10 minutes in bleach or left untreated, and extracted DNA was used to prepare DNA libraries using a restriction-site associated DNA (RAD) approach. Our results demonstrate that intraspecific DNA contamination affects patterns of individual and population variability, causes an excess of heterozygotes, and biases estimates of population structure. Bleach decontamination was effective at removing intraspecific DNA contamination and compatible with RAD sequencing, producing high-quality sequences, reproducible genotypes, and low levels of missing data. Although sperm contamination may be specific to broadcast spawners, intraspecific contamination of samples may be common and difficult to detect from high-throughput sequencing data, and can impact downstream analyses.
Ultra-deep sequencing of HIV-1 near full-length and partial proviral genomes reveals high genetic diversity among Brazilian blood donors
<p>Here, we aimed to gain a comprehensive picture of the HIV-1 diversity in the northeast and southeast part of Brazil. To this end, a high-throughput sequencing-by-synthesis protocol and instrument were used to characterize the near full length (NFLG) and partial HIV-1 proviral genome in 259 HIV-1 infected blood donors at four major blood centers in Brazil: Pro-Sangue foundation (São Paulo state (SP), n 51), Hemominas foundation (Minas Gerais state (MG), n 41), Hemope foundation (Recife state (PE), n 96) and Hemorio blood bank (Rio de Janeiro (RJ), n 70).</p>
Genetic diversity, genetic differentiation and demographic history of Cryptomeria (Cupressaceae), a Tertiary relict plant in East Asia based on RAD sequencing
<p>Genetic structure and distribution patterns of modern floras are strongly affected by climatic change and geographical isolation. In the present study, we applied restriction-site-associated DNA sequencing (RAD-seq) to analyze the genetic structure and to simulate the demographic history of two extant <em>Cryptomeria</em> species in Japan (<em>C. japonica</em>) and Southeastern China (<em>C</em>. <em>japonica</em> var. <em>sinensis</em>). Thirteen natural populations representing the entire species distributed in East Asia were collected from Japan and China. At the species level, the genetic diversity of <em>Cryptomeria</em> was moderate (<em>H<sub>o</sub></em> = 0.217, <em>H<sub>e</sub></em> = 0.203) with a significant genetic differentiation among populations (85.30%, P < 0.001), especially between Japan and China lineages (<em>F</em><sub>ST</sub> = 0.147). Except for the Lushan (LS) population in China, all populations were clustered into two lineages (Japanese and Chinese), which was consistent with their geographical distribution. Approximate Bayesian computations (ABC) model indicated that the current two geographical lineages diverged from a common ancestral lineage and that their divergence time was about 0.417 ~ 0.139 million years ago (Mya). Geographical isolation, climate change in the Quaternary, and human disturbance played important roles in genetic variation and distribution patterns of <em>Cryptomeria</em> in East Asia. Our results shed light on the speciation processes of <em>Cryptomeria</em> and provide a reference for the conservation of this species.</p>
Data from: Evaluating genotyping-in-thousands by sequencing as a genetic monitoring tool for a climate sentinel mammal using non-invasive and archival samples
<p>Genetic tools for wildlife monitoring can provide valuable information on spatiotemporal population trends and connectivity, particularly in systems experiencing rapid environmental change. Though many DNA sequencing approaches still require high quality and quantity of DNA obtained from traditional sources (e.g. blood and tissue), rapid genotyping tools such as Genotyping-in-Thousands by sequencing (GT-seq) have improved our ability to make use of degraded and less concentrated DNA commonly obtained from non-invasive and archival samples. Here, we developed a multi-purpose GT-seq panel (307 single nucleotide polymorphisms) for a climate sentinel mammal (the American pika, <em>Ochotona princeps</em>) for use as a genetic tool for monitoring populations in the Canadian Rocky Mountains. We optimized the panel using contemporary tissue samples (n = 77) and subsequently applied it to archival tissue (n = 17) and contemporary fecal pellet samples (n = 129) to evaluate its effectiveness at identifying individuals and sex, estimating relatedness, and inferring population structure. The panel demonstrated high efficacy with contemporary and archival tissue samples (94.7% and 90.5% genotyping success, respectively) and negligible genotyping error (0.001% and 0.0%, respectively). Despite relatively high genotyping success for fecal pellet samples (79.7%), high genotyping error (28.4%) limited its power as a monitoring tool to assess genetic variation using non-invasive samples and highlighted the need for further optimization around sample and data collection.</p>
Raw Data for the article: Liver Transplantation for Unresectable Intrahepatic Cholangiocarcinoma: The Role of Sequencing Genetic Profiling
<p>Intrahepatic cholangiocarcinoma (iCCA) is a rare and aggressive primary liver tumor, characterized by a range of different clinical manifestations and by increasing incidence and mortality rates even after curative treatment with radical resection. In recent years, growing attention has been devoted to this disease and some evidence supports liver transplantation (LT) as an appropriate treatment for intrahepatic cholangiocarcinoma; evolving work has also provided a framework for better understanding the genetic basis of this cancer. The aim of this study was to provide a clinical description of our series of patients complemented with Next-Generation Sequencing genomic profiling. From 1999 to 2021, 12 patients who underwent LT with either iCCA or a combined hepatocellular and cholangiocellular carcinoma (HCC-iCCA) were included in this study. Mutations were observed in gene activating signaling pathways known to be involved with iCCA tumorigenesis (KRAS/MAPK, P53, PI3K-Akt/mTOR, cAMP, WNT, epigenetic regulation and chromatin remodeling). Among several others, a strong association was observed between the Notch pathway and tumor size (point-biserial <em>rho<sub>pb</sub></em> = 0.93). Our results are suggestive of the benefit potentially derived from molecular analysis to improve our diagnostic capabilities and to devise new treatment protocols, and eventually ameliorate long-term survival of patients affected by iCCA or HCC-iCCA.</p>
