Strong Purifying Selection at Synonymous Sites in D. melanogaster [PDF]

open access: yes, 2013
Synonymous sites are generally assumed to be subject to weak selective constraint. For this reason, they are often neglected as a possible source of important functional variation. We use site frequency spectra from deep population sequencing data to show that, contrary to this expectation, 22% of four-fold synonymous (4D) sites in D.

Target gene selection for sprayable dsRNA‐based biopesticide against Tetranychus urticae Koch (Acari: Tetranychidae)

open access: yesPest Management Science, EarlyView.
Silencing Prosbeta‐5 and Prosbeta‐1 resulted in high mortality in Tetranychus urticae, identifying them as potential target genes for double‐stranded RNA‐based biopesticides using spray‐induced gene silencing (SIGS). Abstract BACKGROUND Because of the excessive use of synthetic chemicals, the two‐spotted spider mite, Tetranychus urticae Koch, a highly ...
