1-Deoxy-D-xylulose 5-phosphate synthase alleles responsible for enhanced terpene biosynthesis

摘要

This invention relates to new polypeptides having a 1-deoxy-D-xylulose 5-phosphate synthase (DXS) activity, which polypeptides comprise a sequence having at least 90 % identity with the sequence SEQ ID N° 1 or fragments thereof. These polypeptides are responsible of a massive accumulation of terpenes in cells.;The invention also relates to transgenic plants, bacteria or yeast that express this polypeptide, and capable of a greatly enhanced accumulation of terpenes, in comparison to plants, bacteria or yeast expressing a typical DXS gene.;The invention also relates to a method of production of terpenes by culturing transgenic plants, bacteria or yeast that express this polypeptide.;Finally the invention relates to transgenic plants that express this polypeptide, and resistant to clomazone.
