Oligonucleotide-mediated RNP-CRISPR-Cas9 genome editing of SDI1 to confer carboxin resistance. (a) Illustration of the substitution required to give a carboxin resistant form of the succinate dehydrogenase subunit product of MGG_00167 and the oligonucleotide donor DNAs capable of introducing the required one nucleotide change necessary tested. Also indicated is the genomic target sequence of the SDI1-targeting RNP-CRISPR-Cas9 complex employed. (b) Diagram showing the RNP used and the predicted DSB at the SDI1-targeting RNP-CRISPR-Cas9 genomic target sequence. (c) Graph showing the number of transformants obtained using the different donor DNAs indicated in a. in combination with the RNP illustrated in b. (d) Transformants from the 80 bp long donor DNA shown in panel a. transformed together with the RNP complex illustrated in panel b. and also showing control plates where only the donor DNA without RNP was transformed (although no transformants are visible on the control plates, using the RNP+ the 30 bp donor one carboxin resistant transformant was obtained which may indicate that very rarely the short oligos can recombine in the absence of the RNP complex; no other carboxin resistant transformants were obtained in the other controls).
