摘要

菊花属植物。研究发现，（–）-α-thujone、（+）-β-thujone、龙脑等萜类化合物是印度香茅的主要成分（Jian et al.2014）。萜烯合成酶（TPS）是研究甾体生物合成的关键酶。根据结构和反应机理，植物中的TPS主要可分为两类。I类是指由金属离子如Mn2+和Mg2+去除焦磷酸基团引起的离子依赖性TPS（Tholl 2015）。II类是指质子依赖性TPS，其导致焦磷酸基团通过环氧化或碳-碳双键质子化离开（Tholl 2015）。根据其氨基酸的相关性，TPS家族可从TPSa-TPSg分为七个亚家族

Identification and Functional Characterization of a New Terpene Synthase Gene from Chrysanthemum indicum var. aromaticum

in the Chrysanthemum genus. Studies have found that (–)-α-thujone, (+)-β-thujone, borneol and other terpenoids are the main components of C. indicum var. aromaticum (Jian et al. 2014). Terpene synthase (TPS) is a key enzyme that is studied in the biosynthesis of steroids. According to the structure and reaction mechanism, TPS in plants can be mainly divided into two categories. Class I refers to the ion-isation-dependent TPS caused by the removal of the pyrophosphate groups by metal ions such as Mn 2+ and Mg 2+ (Tholl 2015). Class II refers to the proton-ation-dependent TPS that causes the pyrophosphate group to leave by epoxidation or carbon-carbon double bond protonation (Tholl 2015). The TPS family can be divided into seven subfamilies from TPSa-TPSg according to the correlation of its amino acid
