Applications of CRISPR/Cas9 Technology in Ornamental Plants

Abstract

Gene editing allows for precise editing and modification of specific target genes within an organism’s genome. The CRISPR/Cas9 technology has become the most widely used gene editing technique. Ornamental traits determine the aesthetic value of plants, and improving ornamental traits has become a research hotspot. The gene editing technology mediated by the CRISPR/Cas9 system has been widely applied in crop genetics and breeding, and there are increasing reports of its application in flowers. This article reviews specific cases of CRISPR/Cas9 technology in ornamental plants, summarizes its current application status and enormous potential in ornamental plants, and hopes to provide a reference for its better application in flower breeding.
