Extended TAQing system for large‐scale plant genome reorganization

SUMMARY We previously developed a large‐scale genome restructuring technology called the TAQing system. It can induce genomic rearrangements by introducing transient and conditional formation of DNA double‐strand breaks (DSBs) via heat activation of a restriction enzyme TaqI, which can cleave DNA at 5′‐TCGA‐3′ sequences in the genome at higher temperatures (37–42°C). Such heat treatment sometimes confers lethal damage in certain plant species...
