The aquatic animals’ transcriptome resource for comparative functional analysis

BMC Genomics
PMCID: 5954267
PMID: 29764375
DOI: 10.1186/s12864-018-4463-x

[…] pipeline of RNA-seq data [] by combining Oases, SOAPdenovo-Trans, and Trinity assemblers. To obtain complete transcriptomes from various assemblers [, ], we used the CD-HIT-EST cluster tool to merge Oases, SOAPdenovo-Trans, and Trinity assembling results. This combinational approach significantly reduce the transcript number and keeping a representative sequence for each unigene. Second, the gene […]


Transcriptome profiling of the honeybee parasite Varroa destructor provides new biological insights into the mite adult life cycle

BMC Genomics
PMCID: 5936029
PMID: 29728057
DOI: 10.1186/s12864-018-4668-z

[…] The read quality of the RNA-seq libraries was evaluated using FastQC []. Cleaned and filtered reads were de novo assembled using DRAP version 1.7 (de novo RNA-seq Assembly Pipeline) [] with the Oases assembler [] and filtered with at least one FPKM. The resulting contigs were aligned with NCBI blast (blastx program, version 2.2.26, e-value under 1e-5) on Refseq protein, Swissprot and Ensembl […]


A Possible Trifunctional β Carotene Synthase Gene Identified in the Draft Genome of Aurantiochytrium sp. Strain KH105

PMCID: 5924542

[…] equences, 150 bp ×2). A total of 113.6 Gbp nucleotide (Gbn) sequence data were obtained, 71.8% of which (81.6 Gbn) had a quality value ≥30. These high-quality sequences were assembled with the Velvet/Oases assembler with a hash length of 37 []. Trinity assemblies were also used []. As a result, we obtained 112,852 contigs (29.3 Mbp) over 100 bp with an N50 size of 1575 bp. Of these, 88,570 (78%) h […]


Sequence analysis of the potato aphid Macrosiphum euphorbiae transcriptome identified two new viruses

PLoS One
PMCID: 5875755
PMID: 29596449
DOI: 10.1371/journal.pone.0193239

[…] iversity of gene expression patterns and consequently a more comprehensive transcriptome set to be derived. The reads were de novo assembled into 22,137 contigs (N50 = 2,130 bp) using the SEED/Velvet/Oases approach []. Various de novo transcriptome assembly algorithms are freely available. Each has advantages and disadvantages and one has to choose among different assemblers the most suitable for […]


Efficient anchoring of alien chromosome segments introgressed into bread wheat by new Leymus racemosus genome based markers

BMC Genet
PMCID: 5872505
PMID: 29587653
DOI: 10.1186/s12863-018-0603-1

[…] r. 1.0.3 and Trinity ver. 2.1.1 [] in sequencing reads derived from control condition. Contigs assembled by Velvet-Oases used various kmer-sizes (39, 49, 59, 69, 79, 89 and 99)(Velvet version 1.2.10, Oases version 0.2.8), and all the contigs assembled by various kmer-sizes were merged into a contig. Contigs assembled by either SOAPdenovo-Trans or Trinity used optimized K-mers. There are three asse […]


A global ocean atlas of eukaryotic genes

Nat Commun
PMCID: 5785536
PMID: 29371626
DOI: 10.1038/s41467-017-02342-1

[…] al RNA-like reads were excluded using sortmeRNA. Resulting reads from each metatranscriptomic sample were assembled using velvet v.1.2.07 with a kmer size of 63. Isoform detection was performed using oases 0.2.08. Contigs smaller than 150 bp were removed from further analysis. Assembly results and descriptive statistics for each sample are shown in Supplementary Data . Similar sequences from more […]
