Analyses of high-throughput transcriptome sequences of non-model organisms are based on two main approaches: de novo assembly and genome-guided assembly using mapping to assign reads prior to assembly. Given the limits of mapping reads to a reference when it is highly divergent, as is frequently the case for non-model species, we evaluate whether using blastn would outperform mapping methods fo...

The complete genome sequence of a Papaya ringspot virus (PRSV) isolate from South Korea (SK) infecting squash (Cucurbita pepo) was obtained using paired-end RNA sequencing. A BLASTn search of the PRSV SK isolate full-genome sequence showed nucleotide sequence identity ranging from 81% to 83% with previously reported PRSV isolates (GenBank accession numbers KX655874 and EF017707).

Fact checking of the recent report of Johnson et al. of the CDC (1) discloses errors of fact and misrepresentations in their critique of the work of Sapi et al. (2). The CDC authors have produced three 603-base nucleotide haplotypes (partial sequences for PyrG open reading frame gene equivalents) and deposited these in GenBank under the accession numbers KF170280.1 (allegedly derived from Borre...

We report here the complete genome of a Dezidougou virus (DEZV) isolated from a passaged culture of the Zika virus strain DAK AR 41524. The consensus DEZV sequence we recovered shows 99% nucleotide similarity using BLASTN to a previously reported DEZV (accession no. JQ675604.1). The current sequence has additional repeat regions as well as a deleted repeat region, which we confirmed by Sanger s...

This study aimed to determine the prevalence and molecular characterization of Sarcocystis spp. in bovine minced meat that is sold various grocery stores butcher shops Van Province Turkey. For this purpose a total 150 samples were obtained from ?pekyolu, Tu?ba, Edremit, Erci?, Geva? districts monthly periods May October 2019. 28% (42/150) found positive for species as result microscopic analyse...

UNLABELLED We have developed a program, MPBLAST, that increases the throughput of batch BLASTN searches by multiplexing (concatenating) query sequences and thereby reducing the number of actual database searches performed. Throughput was observed to increase in reciprocal proportion to the component sequence length. For sequencing read-sized queries of 500 bp, an order of magnitude speed-up was...

UNLABELLED We developed a CGI/Perl-based web server to perform in silico polymerase chain reaction (PCR) on PCR primer sequences. The PUNS (Primer-UniGene Selectivity) server simulates PCR reactions by running BLASTN analysis on user-entered primer pairs against both the transcriptome and the genome to assess primer specificity. PUNS is particularly suited for the identification of highly selec...

SUMMARY Zerg is a library of sub-routines that parses the output from all NCBI BLAST programs (Blastn, Blastp, Blastx, Tblastn and Tblastx) and returns the attributes of a BLAST report to the user. It is optimized for speed, being especially useful for large-scale genomic analysis. Benchmark tests show that Zerg is over two orders of magnitude faster than some widely used BLAST parsers. AVAIL...

BACKGROUND Cephalopoda are a class of Mollusca species found in all the world's oceans. They are an important model organism in neurobiology. Unfortunately, the lack of neuronal molecular sequences, such as ESTs, transcriptomic or genomic information, has limited the development of molecular neurobiology research in this unique model organism. RESULTS With high-throughput Illumina Solexa sequ...
