**3. Application and recent advances**

Today, the application of the CRISPR/Cas9 system-based genome editing for crop improvement has already begun its movement despite still being in its infancy. As a matter of fact, there are already numerous publications that reported that this technology has been successfully implemented in a broad range of plant species (as shown in **Table 1**).

The applications of the CRISPR/Cas9 system in plants can be classified into three types, which are the gene disruption, gene insertion and gene regulation.
