摘要
色彩和香味是影响园林植物观赏品质的重要因子,对植物的观赏价值具有决定性的影响。类胡萝卜素是植物重要色素物质,单萜是植物关键芳香成分,牻牛儿基牻牛儿基焦磷酸合成酶基因(GGPPS)位于两者合成途径的关键交叉节点,对植物颜色、香味相关代谢物的形成具有重要影响。本研究对GGPPS蛋白的结构与分类、进化聚类情况,并对GGPPS基因的转录调控和其他调控因子进行综述,总结了GGPPS基因影响植物色彩与香味形成的作用机制,探讨了其在植物色彩及香味性状改良方面的应用潜力,认为今后可利用多组学手段挖掘相关转录因子并解析GGPPS基因调控植物色香的分子网络,以期为植物观赏性状的遗传改良工作提供新的基因资源和研究思路。
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.
