Cas9 protein accumulation and its catalytic activity with decreasing concentrations of pHcoCas9. (a) BsgI restriction digest assay of transgenic 16c plants co-infiltrated with cultures of TRBO-G-3′gGFP at OD600 0.5 and pHcoCas9 using OD600 values of 0.5, 0.25, 0.125, and 0.0625. Agroinfiltrated N. benthamiana leaf tissue was sampled at 7 dpi. The red arrow indicates indel containing DNA. (b,c) Cas9 (164-kDa) expression was analyzed at 7 dpi using western blotting of infiltrated plants using concentrations of 0.5, 0.25, 0.125, and 0.0625 gGFP delivery constructs in the top panels. Protein loading controls were assayed through Coomassie Blue protein staining and visualization of Rubisco (55-kDa). (b) pHcoCas9 co-infiltrated with TRBO-G-3′gGFP, a TMV replicase-producing construct. (c) pHcoCas9 co-infiltrated with the TRBO replicase mutant (RM) construct RM-gGFP.
