TECHNOLOGY FOCUS - AGRICULTURE - Preferred Process: The process (P1) further involves extracting lipid from the plant part. The plant part is harvested from the plant at a time between about the time of flowering of the plant to about the time senescence of the plant has started. The process (P1) involves harvesting the plant part from a plant grown in the field with a mechanical harvester, drying, or drying and grinding, the plant part prior to extracting the lipid, recovering the extracted lipid by collecting it in a container, at least one of degumming, deodorizing, decolourizing, drying or fractionating the extracted lipid, removing at least some waxes and/or wax esters from the extracted lipid, and analyzing the fatty acid composition of the extracted lipid. The process (P1) has at least one of the following features: i) oleic acid comprises at least 19% of the total fatty acid content in the non-polar lipid in the plant part, ii) palmitic acid comprises at least 20% of the total fatty acid content in the non-polar lipid in the plant part, iii) linoleic acid comprises at least 15% of the total fatty acid content in the non-polar lipid in the plant part, and iv) alpha -linolenic acid comprises less than 15% of the total fatty acid content in the non-polar lipid in the plant part. The process (P1) further involves feeding the plant part to an animal, where the plant part comprises the exogenous polynucleotides.    TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The plant part is an aerial plant part and/or a green plant part, preferably plant leaf. The plant part has a total non-polar lipid content of at least 10 wt.% dry weight, preferably at least 15 wt.% dry weight, especially at least 11 wt.% dry weight.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The extracted lipid comprises triacylglycerols, where the triacylglycerols comprise at least 90 wt./wt.% the extracted lipid; and/or the extracted lipid comprises free sterols, steroyl esters, steroyl glycosides, waxes and/or wax esters. The non-polar lipid of the plant part comprises a fatty acid which comprises a hydroxyl group, an epoxy group, a cyclopropane group, a triple carbon-carbon bond, conjugated double bonds, and/or a branched chain such as a methylated and/or hydroxylated branched chain. The total fatty acid content in the non-polar lipid of the plant part comprises at least 2% more oleic acid and/or at least 2% less palmitic acid than the non-polar lipid in a corresponding wild-type plant part. The non-polar lipid of the plant part comprises a modified level of total sterols, non-esterified sterols, steroyl esters or steroyl glycosides relative to the non-polar lipid in a corresponding wild-type plant part. The DGAT is DGAT1. The exogenous polynucleotides further encode Oleosin; glycerol-3-phosphate acyltransferase (GPAT); or monoacylglycerol acyltransferase (MGAT). EXAMPLE - No suitable example given.
