Figure Lengend Snippet: Base editing in EcN and cyanobacterium Synechococcus elongatus PCC7942 with XSTART . A , sequencing results of argH in EcN edited by XSTART with pBeSpRY-argH. B , phenotypical evaluation of the argH -inactivated EcN. C , customization of XSTART for cyanobacteria via replacing the dCas9–AID module on pSY plasmid with the dSpRY–AID module. D , sequencing results of nblA in S . elongatus PCC7942. E , phenotypical evaluation of the nblA -inactivated S . elongatus PCC7942 in nitrogen-rich and depletion conditions. The edited loci are indicated by red arrows and highlighted in red . Three independent isolates of the edited strain were randomly chosen for phenotypical evaluation, and all tested strains were plasmid cured. AID, activation-induced cytidine deaminas; EcN, E . coli Nissle 1917.
Article Snippet: E . coli MG1655 (CGSC#6300) strain, EcN strain, and cyanobacteria S . elongatus PCC7942 (American Type Culture Collection 33912) strain were used to test the feasibility of base-editing system.
Techniques: Sequencing, Plasmid Preparation, Activation Assay
