CRISPR-Cas9-based editing offers a simple yet efficient method for introducing targeted mutations in the genes of interest. Low efficiency of transformation and a lack of reproducibility in editing genes in elite wheat cultivars are the bottlenecks in improving simply inherited traits. We describe a high-efficiency transformation protocol for editing elite wheat cultivars using JD633-GRF4-GIF1 CRISPR vector. This vector reduces the regeneration time of transformants to less than 90 days and enables transformation of elite cultivars.

摘要

CRISPR-Cas9-based editing offers a simple yet efficient method for introducing targeted mutations in the genes of interest. Low efficiency of transformation and a lack of reproducibility in editing genes in elite wheat cultivars are the bottlenecks in improving simply inherited traits. We describe a high-efficiency transformation protocol for editing elite wheat cultivars using JD633-GRF4-GIF1 CRISPR vector. This vector reduces the regeneration time of transformants to less than 90 days and enables transformation of elite cultivars.
