Polyprenols, a type of universal glycan lipid carrier, play important roles for glycan bio-assembly in wide variety of living systems. Chemical synthesis of natural polyisoprenols such as undecaprenol and dolichols, but especially their homologs, could serves as a powerful molecular tool to dissect and define the functions of enzymes involved in glycan biosynthesis. In this paper, we report an efficient

Herein we report the synthesis of two fluorescently labelled analogues of C25 dolichol (Dol25) in which the terminal isoprene unit has been replaced by a dansyl or 7-amino-4-trifluoromethylcoumarin fluorophore, a transformation enabled by the regioselective epoxidation of the terminal olefin via its bromohydrin using the van Tamelen procedure. The lipid alcohols were phosphorylated and glycosylated

This invention pertains to a method for manipulating the growth rate and/or yield and/or architecture of a genetically modified plant, as compared to a corresponding wild-type plant. The method relies on over-expression of an endogenous or exogenous gene encoding a cis-prenyltransferase enzyme. In a preferred embodiment, transgenic plants obtained by this method exhibit increased growth rates to maturity, increased seed production, and increased height, siliques, and leave area.
