Abstract: The present invention relates to transgenic plants, or parts thereof, with modified traits, as well as methods of selecting and using these plants or parts. In particular, the present invention relates to a transgenic plant, or part thereof, comprising a first exogenous polynucleotide which encodes a transcription factor polypeptide that increases the expression of one or more glycolytic and/or fatty acid biosynthetic genes in the plant or part thereof, and a second exogenous polynucleotide which encodes a polypeptide involved in the biosynthesis of one or more non-polar lipids. Furthermore, in addition to an increased triacylglycerol (TAG) content relative to a corresponding wild-type plant or part thereof, the plant or part thereof have a modified phenotype selected from; an increased soluble protein content, an increased nitrogen content, a decreased carbon:nitrogen ratio, increased photosynthetic gene expression, increased photosynthetic capacity, decreased total dietary fibre (TDF) content, increased carbon content and an increased energy content.

Abstract: The present invention relates, inter alia, to vegetative plant parts, such as from a Sorghum sp. and/or a Zea mays plant, which comprise a total fatty acid (TFA) content which comprises fatty acids esterified in the form of triacylglycerols (TAG) and fatty acids in the form of lipids other than TAG, wherein the vegetative plant parts comprise greatly increased levels of TFA, for example a TFA content of about 5% (w/w dry weight). The present invention also relates to the use of the vegetative plant parts as a feedstuff, and/or to produce a feedstuff, for animal consumption.

Abstract: The present invention relates to methods of producing industrial products from plant lipids, particularly from vegetative parts of plants. In particular, the present invention provides oil products such as biodiesel and synthetic diesel and processes for producing these, as well as plants having an increased level of one or more non-polar lipids such as triacylglycerols and an increased total non-polar lipid content. In one particular embodiment, the present invention relates to combinations of modifications in two or more of lipid handling enzymes, oil body proteins, decreased lipid catabolic enzymes and/or transcription factors regulating lipid biosynthesis to increase the level of one or more non-polar lipids and/or the total non-polar lipid content and/or mono-unsaturated fatty acid content in plants or any part thereof. In an embodiment, the present invention relates to a process for extracting lipids. In another embodiment, the lipid is converted to one or more hydrocarbon products in harvested plant vegetative parts to produce alkyl esters of the fatty acids which are suitable for use as a renewable biodiesel fuel.
