Abstract

Terpeniod compound can be classified into monoterpenes((C5H8)₂),sesquiterpenes((C5H8)₃),

diterpenoids((C5H8)₄),triterpenoids((C5H8)₆) and polyterpenes((C5H8)₂,n>6) according to the numbers of Isoprene or isopentane((C5H8)n) and the derivative of having the oxygen and different saturation degree from the structure.The biosynthesis of different terpeniod compound can be produced depends on cross-talk between the MEP pathway and the mevalonate (MVA) pathway. IDI（Isopentenyl diphosphate isomerase）is the common and key enzyme related to the biosynthesis of terpeniod and gibberellin compounds.It is well known that the IDI gene families exit in the diverse species of the earth and have been carried out the research works in the plants of  Arabidopsis annua L./Artemisia apiacea、the fungus of Ganoderma lucidum etc.Why do I think the essential and important of IDI gene families regarding the biosynthesis of terpenoids compound?Because IDI gene families locate in the upstream of the pathway.The function and change of it can bring the influences or actions to the whole course of metabolism pathway and downstream products.We can not ignore the essence of research courses or dynamics on the direction of research projects.The quantities of IDI gene families are found it is not same or diverse because of the assay and characteristics involved in the species.Moreover,IDI gene families has the certain function during the course of reciprocal transformation between the gene families of IPP and DMAPP.I will give the review in the way of presentation from the aspects of exist formation,identification,cloning sequences,tissue-specific expression,protein structures and functions and applications of the different creatures so as to acquire the supports and good advice coming from the experts who are interested and has the famous experience about the research projects.
