Targeted base editing in the mitochondrial genome of Arabidopsis thaliana.

ABSTRACT: Beyond their well-known role in respiration, mitochondria of land plants contain biologically essential and/or agriculturally important genes whose function and regulation are not fully understood. Until recently, it has been difficult to analyze these genes or, in the case of crops, to improve their functions, due to a lack of methods for stably modifying plant mitochondrial genomes. In rice, rapeseed, and Arabidopsis thaliana, mitochondria-targeting transcription activator-like effector nucleases (mitoTALENs) have recently been used to disrupt targeted genes in an inheritable and stable manner. However, this technique can also induce large deletions around the targeted sites, as well as cause ectopic homologous recombinations, which can change the sequences and gene order of mitochondria
