Abstract:

Color and aroma are important factors that affect the ornamental quality of garden plants and have a decisive impact on their ornamental value. Carotenoids are important pigment substances in plants and are key aromatic components in plants. The geranylgeranyl pyrophosphate synthase gene (GGPPS), which is located at a critical intersection of the two synthesis pathways, has a considerable impact on the formation of plant color and aromatic-related metabolites. This study reviews the structure, classification, and evolutionary clustering of GGPPS proteins, transcriptional regulation of GGPPS genes, and other regulatory factors. We further summarize the mechanism by which GGPPS genes affect the formation of plant color and aroma and explore their potential applications in improving plant color and aroma traits. The aim of this study is to provide new genetic resources and research ideas for the genetic improvement of ornamental plant traits.

Key words: GGPPS gene, color, aroma, terpenoids, ornamental plant
