  • Patent number: 10006039
    Abstract: 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.

  • Patent number: 9593344
    Abstract: In the tgd1-1 mutant that displays substantially enhanced TAG synthesis and turnover, disruption of SUGAR-DEPENDENT1 (SDP1) TAG lipase or PEROXISOMAL TRANSPORTER1 (PXA1) severely decreases FA turnover, leading to an increase in leaf TAG content up to 9% of dry weight and total leaf lipid by three-fold. The membrane lipid content and composition of tgd1-1 sdp1-4 and tgd1-1 pxa1-2 double mutants are altered and they are compromised in growth and development and fertility.

  • Publication number: 20140031573
    Abstract: Combinations of genes are used to enhance the accumulation of triacylglycerol compounds in vegetative tissues of plants. Fatty acids in the form of triacylglycerol compounds accumulate in vegetative tissues in excess amounts compared to untreated plants.
