Synthetic guide RNA sequence 1 for botR integration
Synthetic guide RNA sequence 1 for the integration of several botR constructs at the pyrE locus of the C. sporogenes genome
Usage and Biology
Synthetic guide RNA sequence 1 for the use of CRISPR-Cas9 for genomic integration of various botR constructs in the generation of our volatile reporter strains for predicting neurotoxin production following food manufacture. Genomic integration of these constructs was at the pyrE locus of C. sporogenes.
Characterisation
This part was the guide RNA sequence that allowed our CRISPR system to work. As we integrated BotR in to the genome via double homologous crossover (replacing the ΔpyrE gene), the CRISPR systems was designed to kill the C. spororgenes that botR did not successfully integrate in to, this part was the guide RNA sequence that allowed the CRISPR system to cut in the event a double homologous crossover did not happen.
