View the Complete Application at the US Patent & Trademark Office
The present invention relates to compositions and methods for providing RNA interference (RNAi) vectors comprising trigalactosyldiacylglycerol (tgd) biosynthesis enzyme constructs for increasing oil content of plants. Further, the use of tgd RNAi silencing vectors in combination with co-expression of heterologous oil regulating transcription factors, such as WRINKLED1, are contemplated to overcome the reduced growth and variable levels of embryonic lethality in plants with reduced TGD protein. Additionally, plants having reduced APS1, a gene encoding a major catalytic isoform of the small subunit of AGPase (AGP(-) plants), co-expressing a heterologous oil modulating transcription factor are contemplated for use in combination with plants having reduced TGD. Oil harvested from vegetative tissues of plants comprising vectors and genes of the present invention is contemplated for use in biofuel and biodiesel products.
