MOTIVATION Transcriptome sequencing has long been the favored method for quickly and inexpensively obtaining a large number of gene sequences from an organism with no reference genome. Owing to the rapid increase in throughputs and decrease in costs of next- generation sequencing, RNA-Seq in particular has become the method of choice. However, the very short reads (e.g. 2 × 90 bp paired ends) f...

Premise of the study The use of genome skimming allows systematists to quickly generate large data sets, particularly of sequences in high abundance (e.g., plastomes); however, researchers may be overlooking data in low abundance that could be used for phylogenetic or evo-devo studies. Here, we present a bioinformatics approach that explores the low-abundance portion of genome-skimming next-gen...

BACKGROUND De novo assembly of non-model organism's transcriptomes has recently been on the rise in concert with the number of de novo transcriptome assembly software programs. There is a knowledge gap as to what assembler software or k-mer strategy is best for construction of an optimal de novo assembly. Additionally, there is a lack of consensus on which evaluation metrics should be used to a...

The narrow genetic base and limited genetic information on Arachis species have hindered the process of marker-assisted selection of peanut cultivars. However, recent developments in sequencing technologies have expanded opportunities to exploit genetic resources, and at lower cost. To use the genetic information for Arachis species available at the transcriptome level, it is important to have ...

The first sentence of the second paragraph of the ‘‘Assemblies’’ subsection of the Methods should have cited reference 34 instead of 33. The correct sentence should read: The Illumina datasets were assembled using SOAPdenovo 1.05 [34] using following parameters: ‘‘-K 23 -L 70 -M 3 -u -R -F’’. The fourth sentence of the first paragraph of the ‘‘Importance of Quality Control for Illumina Data’’ s...

BACKGROUND The oriental fruit moth, Grapholita molesta, is an extremely important oligophagous pest species of stone and pome fruits throughout the world. As a host-switching species, adult moths, especially females, depend on olfactory cues to a large extent in locating host plants, finding mates, and selecting oviposition sites. The identification of olfactory genes can facilitate investigati...

Canada is the world’s largest producer of canola and the trend of production is ever increasing with an annual growth rate of 9.38% according to FAOSTAT [1]. In 2017, canola acreage surpassed wheat in Saskatchewan, the highest producer of both crops in Canada. Country-wide, the total farming area of canola increased by 9.9% to 22.4 million acres while wheat area saw a slight decline to 23.3 mil...
