Flowering with CRISPR

Multiplexed heritable gene editing using RNA viruses and mobile single guide RNAs

FT (Flowering Locus T) is a small protein that helps plants know when to flower. Now it also allows geneticists to create heritable gene edits in the shoot apical meristem. The trick is a guide RNA augmented with an FT sequence that promotes cell-to-cell mobility. The result is a new approach to gain access to the germline.
