Part:BBa_K2403005
Gal1 promoter>loop for dsRNA
This parts can be used for expressing dsRNA in Saccharomyces Cerevisiae.
Usage and Biology
In order to kill pine wood nematodes by feeding RNAi, we made hairpin loop-dsRNA targeted to the nematodes expressed in budding yeast serving as feed. We used BBa_J63006 as a promoter in that case. This part was used to express hairpin-dsRNA in budding yeast by adding loop [1], [2] to BBa_J63006 . You can create plasmid transcribing dsRNA with hairpin loop which can be expressed in budding yeast by cleaving with restriction enzyme Not1, connecting sense part between the loop part and the promoter, further cleaving with a restriction enzyme, Hind 3 sand connecting antisense strand.
Characterization
The expression level of dsRNA was assayed using Gal1 promoter (BBa_ J63006) and GPD promoter (BBa_ K517001) to characterize the RNA expression ability of these promoter parts.
The results of the detection by qRT-PCR were as follows
Medium Stock plasmid Average value SD Gal MKY13 WT Gal1p-AK1 3.61 0.98 Glu MKY13 WT Gal1p-AK1 0.11 0.00 Glu MKY13 WT GPD-Ak1 0.07 0.02
(The hairpin loop sequence was targeted for the RT-PCR. It was corrected with 25S rRNA. n=3)
