Toehold sensor plasmid B69-mScarlet-I

Sensor plasmid for detecting BYDV

1. Usage and biology

This sensor plasmid was designed to detect a conserved RNA sequence in the barley yellow dwarf virus (BYDV) genome. It should express the reporter protein mScarlet-I only in the presence of its specific trigger sequence. The translation is controlled by a toehold switch, which sequesters the RBS and the start codon in a stable RNA secondary structure. This structure is unfolded in the presence of the specific trigger, which is a conserved sequence in the BYDV genome.

The translational activity can be measured by fluorescence intensity at 569/593 nm. The construct can be used in various reaction set ups. If used in a PURE (protein expression using recombinant elements) system or any other environment with reduced nuclease activity, it can be used as a linear plasmid. However, if used in a reaction with active nucleases, for instance a lysate-based cell-free expression system, the construct should be used as a circular plasmid to reduce degradation.
