Heritable gene editing using FT mobile guide RNAs and DNA viruses.

ABSTRACT:

Background

The virus-induced genome editing (VIGE) system can be used to quickly identify gene functions and generate knock-out libraries as an alternative to the virus-induced gene silencing (VIGS). Although plant virus-mediated VIGE has been shown to have great application prospects, edited genes cannot be transferred to the next generations using this system, as viruses cannot enter into shoot apical meristem (SAM) in plants.

Results

We developed a novel cotton leaf crumple virus (CLCrV)-mediated VIGE system designed to target BRI1, GL2, PDS genes, and GUS transgene in A. thaliana by transforming Cas9 overexpression (Cas9-OE) A. thaliana. Given the deficiency of the VIGE system, ProYao::Cas9 and Pro35S::Cas9 A. thaliana were transformed by fusing 102 bp FT mRNAs with sgRN
