Title Reference genome sequence of Cotesia vestalis: scaffolds and contigs
Downloaded 9 times
Description No genome information was available for C. vestalis. In order to build a draft reference genome and to develop SNP assays, we sequenced the entire genome of C. vestalis on a single lane of paired-end sequences (2x100 bp) on an Illumina HiSeq 2000 (Illumina Inc., U.S.A.) instrument. The SNP discovery panel consisted of eight C. vestalis females, one from each of eight fields.Before assembly, Illumina reads were trimmed using an in-house Perl script that trims the sequence as soon as two consecutive bases have a quality score lower than 20. Reads that after trimming had a length smaller than 50 bp were removed from the analysis. To obtain C. vestalis sequence contigs to be used as a pseudo-reference genome, we performed a de novo assembly on the 133 million 100 bp reads using SOAPDENOVO version 1.05 [37]. The assembly was done using a k-mer size of 45 and k-mers that were seen only once were removed (option –d). After contig construction, scaffolding was performed using intra-scaffold closure (option –F) and a minimum length for scaffolding of 50 bp. The total size of the assembly was 152 Mb with a contig N50 size of 761 bp and a scaffold N50 size of 2400 bp.

Title Cotesia vestalis SNP information and sequences
Downloaded 8 times
Description From our list of putative SNPs across the C. vestalis genome, we selected 100 SNPs for genotyping assay development. We first selected the 200 largest scaffolds; they varied in length from 17-58Kb and contained a total of 7,878 SNPs. We then removed SNPs with a minor allele frequency (MAF) <0.2, SNPs that had another SNP within 50 bp up- or downstream, and SNPs with more than 2 alleles. The remaining SNPs were binned in MAF bins of 0.2-0.3 (1,908 SNPs), 0.3-0.4 (1,605 SNPs) and 0.4-0.5 (1,156 SNPs). Per MAF bin, SNPs were ranked by SNP quality score. We then selected the SNPs with the highest quality scores, picking 20 SNPs with a MAF between 0.2-0.3 and 40 each with a MAF between 0.3-0.4 and 0.4-0.5, all on different scaffolds. All selected SNPs had a quality score of more than 200 (based on SAMTOOLS), and an average read depth of 61. High-throughput genotyping assays based on allele-specific forward primers were developed for these 100 SNP sequences at KBioscience (now LGC Genomics, Hoddesdon, U.K.).

Title Putative SNPs discovered in genome of Cotesia vestalis
Downloaded 40 times
Description Individual paired-end reads were aligned against the artificial Cotesia vestalis reference genome obtained from the de novo genome assembly using BWA. The resulting BAM file was then used for the identification of putative SNPs using SAMTOOLS and varFilter from the utility. We only considered nucleotide substitutions and ignored small indels. SNPs were filtered that had a mapping quality higher than 20, a minimum read depth of 3 and a maximum read depth of 90 (3x the average read depth, a strategy to avoid orthologous SNPs, e.g. in multi copy genes.
