Sociotechnical imaginaries of gene editing in food and agriculture reflect and shape culturally particular understandings of what role technology should play in an ideal agrifood future. This study employs a comparative media content analysis to identify sociotechnical imaginaries of agricultural gene editing and the actors who perform them in five countries with contrasting regulatory and cultural contexts: Canada, Japan, New Zealand, the Netherlands, and the United States. We find that news media in these countries reinforce a predominantly positive portrayal of the technology's future, although variations in which imaginaries are most mobilized exist based on the regulatory status of gene editing and unique histories of civil society engagement around biotechnology in each country. We argue that by granting legitimacy to some narratives over others, the media supports gene editing as a desirable and necessary component of future agrifood systems, thereby limiting consideration of broader issues related to the technology's development and application.

Unlabelled: a natural inhabitant of the human body, is a promising candidate vehicle for vaccine delivery. An obstacle in developing bacterial delivery vehicles is generating a production strain that lacks antibiotic resistance genes and contains minimal foreign DNA. To deal with this obstacle, we have constructed a finetuned, inducible two-plasmid CRISPR/Cas9-system for chromosomal gene insertion in .

Our recent investigations on the function of Drosophila CG11700 and CG32744 (Ubi-p5E) genes using CRISPR/Cas9 deletion technology could not repeat or confirm the results on CG11700 shown in our previous study which was based on P-element excision assay (Zhan et al. 2012). Here by CRISPR/Cas9 editing, we generated mutants of CG32744 with the whole gene body fully deleted from the genome, and truncated mutants of CG11700 with N-terminal 103 aa deleted out of its total 301 aa peptide sequence.

Multidrug-resistant organisms are bacteria that are no longer controlled or killed by specific drugs. One of two methods causes bacteria multidrug resistance (MDR); first, these bacteria may disguise multiple cell genes coding for drug resistance to a single treatment on resistance (R) plasmids. Second, increased expression of genes coding for multidrug efflux pumps, which extrude many drugs, can cause MDR.
