Fig. 3From: The extracellular polysaccharide inhibit porcine epidemic diarrhea virus with extract and gene editing LacticaseibacillusThe genome edition for L. casei genome engineering based on CRISPR-Cas9D10A. A genome editing plasmid deleting the exopolysaccharide biosynthesis gene (glucose-1-phosphate thymidylyltransferase gene, 2179 gene) was constructed in our research in the mechanism diagram (A), The positive genome editing plasmid of L. casei was constructed, and the B shown the diagram losing the glucose-1-phosphate thymidylyltransferase gene, which contain the SgRNA, dCas9, left and right homologous arm genesBack to article page
