The development of clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9 (CRISPR/Cas9) system has revolutionized genome editing and plant breeding. Applications of CRISPR/Cas9 technology in fruit crops, including grapevine, enable precise improvement of agronomically important traits. In this review, we first describe genome editing based on the most widely used CRISPR/Cas9 system and recently developed CRISPR technologies. We then focus on applications of CRISPR/Cas9 in improvement of disease resistance, optimization of CRISPR/Cas9 systems, multiplex genome editing and off-target effect analysis in grapevine. We also discuss the challenges facing genome editing that should be overcome to realize the potential of CRISPR technology in grapevine. Finally, we highlight possible future experimental considerations for more precise and efficient genome editing in grapevine.
