TLDR
The resulting suite of plant prime editors enable point mutations, insertions and deletions in rice and wheat protoplasts through codon, promoter, and editing-condition optimization.
Abstract
Prime editors, which are CRISPR-Cas9 nickase (H840A)-reverse transcriptase fusions programmed with prime editing guide RNAs (pegRNAs), can edit bases in mammalian cells without donor DNA or double-strand breaks. We adapted prime editors for use in plants through codon, promoter, and editing-condition optimization. The resulting suite of plant prime editors enable point mutations, insertions and deletions in rice and wheat protoplasts. Regenerated prime-edited rice plants were obtained at frequencies of up to 21.8%.

Programmable editing of a target base in genomic DNA without double-stranded DNA cleavage

TL;DR: E engineered fusions of CRISPR/Cas9 and a cytidine deaminase enzyme that retain the ability to be programmed with a guide RNA, do not induce dsDNA breaks, and mediate the direct conversion of cytidine to uridine, thereby effecting a C→T (or G→A) substitution.

Programmable base editing of A•T to G•C in genomic DNA without DNA cleavage

TL;DR: Adenine base editors (ABEs) that mediate the conversion of A•T to G•C in genomic DNA are described and a transfer RNA adenosine deaminase is evolved to operate on DNA when fused to a catalytically impaired CRISPR–Cas9 mutant.

Simultaneous editing of three homoeoalleles in hexaploid bread wheat confers heritable resistance to powdery mildew

TL;DR: It is shown that TALEN-induced mutation of all three TaMLO homoeologs in the same plant confers heritable broad-spectrum resistance to powdery mildew, and provides a methodological framework to improve polyploid crops.
