Abstract With the advent of CRISPR/Cas system, plant genome editing has entered a new era of precise editing for any genes of interest. The CRISPR/Cas toolkits have been successfully tested on a wide variety of fruit tree species. According to the statistics of breeding research, researchers have edited about 45 fruit tree genes by CRISPR/Cas genome editing technology, which were mainly used to enhance disease resistance, prolong shelf-time, early flowering, tree dwarf and increase shoot branching. However, the fruit tree genome editing still relies mostly on Cas9-based indel mutation and Agrobacterium-mediated stable transformation. Transient transformation for transgene-free genome editing is preferred, but it typically has very low efficiency in fruit trees, substantially limiting its potential utility. In this review, the CRISPR/Cas system and its related technologies were summarized, and then we introduced the delivery methods of the CRISPR /Cas expression vector into plant genome and the current status of fruit tree genome editing practices using the CRISPR/Cas system, and discussed the problems impeding the efficient application of the CRISPR/Cas toolkits for fruit trees genome editing, as well as future prospects. This review provides reference for research on gene function and molecular breeding of fruit trees.
