- Abstract
β-ionone(β-ionone, ΒI)is an important natural aroma volatile compound widely distributed in plants, which is an apocarotenoid produced by carotenoid cleavage dioxygenases cleaving β-carotene at the 9, 10 and the 9', 10' positions. As a representative of cyclized isoprene, β-ionone has various biological activities such as antibacterial, antiviral and antitumor. Therefore, studies on the biosynthesis and metabolic regulation of β-ionone in plants has gradually become a hot topic. This paper summarizes the progress of β-ionone bioactivity, biosynthesis and regulation in plants, focusing on the β-ionone biosynthesis pathway and its related enzymes, followed by the control of β-ionone biosynthesis by carotenoid cleavage dioxygenase genes at the molecular level, as well as transcription factors such as WRKY, NAC, ERF and MYB regulate the expressions of related structural genes and thus affect β-ionone biosynthesis. And the paper describes the effects of environmental factors such as temperature, light, water and soil salinity on β-ionone biosynthesis in plants. It also introduces the effects of genes involved in the biosynthetic pathway of β-ionone on the color and aroma of plant leaves, flowers and fruits, as well as the improvement of β-ionone biosynthesis in plants using gene overexpression, gene silencing and other genetic engineering techniques, and makes reasonable prospects for the problems to be solved in the research on β-ionone in plants, aiming to provide theoretical assistance for the deeper research on the biosynthesis and regulatory mechanism of β-ionone in plants, and provide a theoretical foundation for improving plant floral aroma substances and obtaining a high yield of natural β-ionone.
