Carotenoid Biofortification of Crops in the CRISPR Era

Carotenoids are micronutrients important for human health. The continuous improvements in clustered regularly interspaced short palindromic repeats (CRISPR)-based genome-editing techniques make rapid, DNA/transgene-free and targeted multiplex genetic modification a reality, thus promising to accelerate the breeding and generation of ‘golden' staple crops. We discuss here the progress and future prospects of CRISPR/Cas9 applications for...
