Development and application of CRISPR/Cas in grapevine

The development and application of CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated protein) technologies have revolutionized genome editing in plants due to its simplicity, high efficiency, and versatility. As an economically important fruit crop worldwide, grapevine genome editing using CRISPR/Cas technologies has also been reported these years.  Here we introduce the development briefly of the most popular CRISPR/Cas9 system and also the state-of-the-art CRISPR technologies developed so far. Moreover, we summarize CRISPR/Cas9-mediated applications for gene functional study and trait improvement in grapevine. Optimization of CRISPR/Cas9 system, as well as the other CRISPR/Cas systems including CRISPR/LbCas12a and base editor in grapevine genome editing, is also discussed. In addition, we discuss the challenges and future perspectives for precision genome editing in grapevine, expecting to present a roadmap for the future applications of CRISPR technology in this species.
