Abstract:

HDS属于GcpE蛋白家族，具4Fe-4S活化中心。植物HDS既是萜类物质前体IPP合成的关键酶，也是单萜和双萜类芳香物质、类胡萝卜素、VE和叶绿素等重要物质合成的关键调控位点。其催化调节的MEP途径所合成的萜类化合物对于植物传粉、对抗天敌、代谢调控等方面具有重要作用。本文主要从基因克隆、基因功能以及基因表达特性比较三个方面来分析比较不同植物MEP途径中的HDS基因，以期深入了解该基因对萜类化合物合成的作用。
HDS belongs to GcpE protein family, with 4Fe-4S activation center. HDS is the key enzyme of terpenoid substances precursor IPP synthesis, monoterpene and double terpenoids aromatic substances, carotenoids, VE and important material such as chlorophyll synthesis of key control site. The MEP pathways that regulate the catalysis of synthesis of TIAs for pollinating plants against predators, metabolic regulation plays an important role in such aspects, the HDS for cloning genes and carries on the correlation analysis to study the effect of the synthesis of TIAs has great significance. In this paper, HDS genes in MEP pathway were compared among different plants from gene cloning, gene function and gene expression characteristics mainly to try to understand the role of HDS gene playing in MEP pathway.
