Abstract
Retron library recombineering (RLR) is a powerful tool in the field of genome editing that exceeds the scope and specificity of the CRISPR/Cas technique. In RLR, single-stranded DNA produced in vivo by harnessing the in-built potential of bacterial retrons is used for replication-dependent genome editing. RLR introduces several genomic variations at once, resulting in pooled and barcoded variant libraries, thus permitting multiplexed applications. Retron-generated RT-DNA has already shown promise for use in genome editing. Thus, this new tool will result in fresh, intriguing, and surprising developments in molecular biology and its juncture with other disciplines of research, including medicine, agriculture, and microbiology. In this review, we discuss the current state of this brand-new tool that could eventually boost genome editing research.
