Abstrakt: Targeted genome editing using CRISPR/Cas9 is a promising technology successfully verified in various plant species; however, it has hardly been used in plant cell suspension cultures. Here, we describe a successful knockout of a green fluorescent protein (gfp) reporter gene in Arabidopsis cell culture. We transformed seven transgenic suspension cell lines carrying one to three gfp gene copies with a binary vector containing genes coding for Cas9 and guide RNAs targeting the gfp gene. We detected the site-specific mutations by restriction analysis of a gfp amplicon. DNA sequencing of the PCR products confirmed high diversity of insertion-deletion mutations in the cell lines after the editing. We also analyzed gfp mRNA expression by real-time PCR and observed a decrease in gfp transcription after the target site modification. We can conclude that the CRISPR/Cas9 system can be successfully used for introducing site-specific mutations into the genome of cultured suspension cells of Arabidopsis. [ABSTRACT FROM AUTHOR]
