FIELD OF INVENTION
The present invention relates to a transcriptome encoding plant enzyme homologous to undecaprenyl pyrophosphate synthase and a gene encoding this enzyme. More particularly, the present invention provides the undecaprenyl pyrophosphate synthase homologues and its application in the production of natural rubber in the plant of Hevea brasiliensis, as well as a transgenic H. brasiliensis plant thereof.
BACKGROUND OF THE INVENTION Natural rubber is a raw material of great importance in most of the industries. It is a high molecular mass polymer of isoprene units with cis configuration. It is naturally produced in over 200 species of plants. However, there are only two of these plants, H. brasiliensis and Parthenium argentatum, produce sufficiently high molecular weight rubber to be utilized for industrial purposes, of which H. brasiliensis is deemed the chief source of commercial rubber. It is known in the art that the world supply of natural rubber is barely keeping up with global demand for 12 million tons of natural rubber in year 2020. As there is an increasing global demand on rubber, further improvement of natural rubber production is necessary. Thus, there is a significant interest in studying rubber biosynthesis and exploring the molecular biology concept involved in this rubber biosynthesis.
