Prospect of CRISPR/Cas9 technology in sustainable landscape plants

Plant breeding is one of the manifestations of sustainable landscape regeneration. The CRISPR/Cas9 system is a new type of genome-directed editing technology modified from the acquired immune defense response in bacteria and archaea. Due to its efficiency and multi-function, it is widely used in animals, plants, microorganisms and other fields. In sustainable plant landscape, the system makes the gene mutate to improve plant varieties, morphological characteristics, and flowering dates, which can increase the variety of landscape. This article discusses the general situation of CRISPR/Cas9 technology and the progress of plant application, summarizing the problems and countermeasures, and looking forward to the application of sustainable landscape plants. Landscape plants are genetically complex. CRISPR/Cas9 technology can improve plants without genome references and cultivate new ornamental varieties, which can accelerate the breeding process of sustainable landscape plants
