Abstract

Modification of plant mitochondrial genomes is still a difficult task, especially in multicellular plants. Transcription activator-like effector nucleases with a mitochondrial localization signal (mitoTALENs) can cut out a desired sequence from the mitochondrial genome in plants. Although vector construction of mitoTALENs is complicated, the modification efficiency is high enough to achieve homoplasmy of multicopy mitochondrial genomes. Here I describe how to design mitoTALENs to select a target, construct a vector, and select the mitochondrial transformants.
