Marker-free carotenoid-enriched rice generated through targeted gene insertion using CRISPR-Cas9

Existing examples of targeted gene insertion in plants either rely on a selectable marker gene or result in short DNA inserts. Here, the authors use an optimized CRISPR-Cas9 method to insert a 5.2 kb carotenoid biosynthesis cassette into genomic safe harbors in rice, and obtain marker-free lines wit...

Description
Summary:Existing examples of targeted gene insertion in plants either rely on a selectable marker gene or result in short DNA inserts. Here, the authors use an optimized CRISPR-Cas9 method to insert a 5.2 kb carotenoid biosynthesis cassette into genomic safe harbors in rice, and obtain marker-free lines with high carotenoid content.
