摘　　要：超基因家族编码的细胞色素P450(CYP450)单加氧酶,是最早被归类为“超级家族”的酶类。研究表明CYP450分布在植物的各组织器官中,具有非常广泛的催化活性,参与了植物生命活动过程中的各种初级和次级代谢。植物中目前鉴定出的CYP450共分为11个家族簇、63个基因家族,来自不同家族簇的CYP450成员分别在植物的各种生命活动中发挥着不同的功能作用。本文针对国内外有关植物CYP450的发现、结构特点以及功能表征等方面的研究进行了总结,重点归纳了CYP450家族成员在植物花色改良、花香物质合成、观赏器官的生长发育、提升抗逆能力等方面发挥的功能作用,以期为深入探究CYP-450在植物重要观赏器官生长发育和在植物面对逆境胁迫提升抗逆性过程中发挥的生理功能提供参考。The cytochrome P450(CYP450)monooxygenases are encoded by a complex gene superfamily.This family was the first group of enzymes classified as a"super family".Previous studies have shown that CYP450 enzymes with a broad range of catalytic activities are distributed in all life domains and participate in various secondary metabolic processes of plants.At present,the CYP450 genes identified in plants are di-vided into 11 clans and 63 gene families.The CYP450 members from different clans play different roles in various biological processes of plants.This paper summarizes the research advances on the discoveries,structural characteristics and functional characterization of plant CYP450s.We focused on the biological functions played by CYP450 family members in plant floral color improvement,the aroma synthesis,growth and development of ornamental organs,and improvement of stress tolerance.This review is expected to pro-vide a reference for further exploration of physiological functions of cYP450s in the growth and development of important ornamental organs of plants and in the process of improving the tolerance of plants to stress.
