Mini CRISPR-Cas12f1: a new genome editing tool.

The clustered regularly interspaced short palindromic repeats and associated protein (CRISPR-Cas) toolbox enables targeted mutations to be introduced into a genome. However, the delivery of appropriately sized Cas effectors to develop transgene-free edited plants is a limiting factor. A novel mini CRISPR-Cas12f1 system recently reported by Wu et al. overcomes this challenge by deploying viral-based vectors and nanoparticles (NPs) as carriers.
