Patent number: 9994792Abstract: The present invention relates generally to the field of recombinant fatty acid synthesis, particularly in transgenic plants. The application describes genes involved in fatty acid synthesis and provides methods and vectors for the manipulation of fatty acid composition of plant oils. In particular, the invention provides constructs for achieving the integration of multiple heterologous genes involved in fatty acid synthesis into the plant genome, such that the resulting plants produce altered levels of polyunsaturated fatty acids. Also described are methods for enhancing the expression of fatty acid biosynthesis enzymes by co-expressing a silencing suppressor within the plant storage organ.Type: GrantFiled: July 7, 2017Date of Patent: June 12, 2018Assignees: COMMONWEALTH SCIENTIFIC AND INDUSTRIAL RESEARCH ORGANISATION, GRAINS RESEARCH AND DEVELOPMENT CORPORATIONInventors: James Robertson Petrie, Anne Maree Mackenzie, Qing Liu, Pushkar Shrestha, Peter David Nichols, Susan Irene Ellis Blackburn, Maged Peter Mansour, Stanley Suresh Robert, Dion Matthew Frederick Frampton, Xue-Rong Zhou, Surinder Pal Singh, Craig Christopher Wood

Patent number: 9976107Abstract: The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids. In particular, the present invention provides ?3 destaurases, ?5 elongases and ?6 desaturases with novel activities. Also provided are methods and DNA constructs for transiently and/or stably transforming cells, particularly plant cells, with multiple genes.Type: GrantFiled: July 27, 2017Date of Patent: May 22, 2018Assignees: COMMONWEALTH SCIENTIFIC AND INDUSTRIAL RESEARCH ORGANISATION, GRAINS RESEARCH AND DEVELOPMENT CORPORATIONInventors: James Robertson Petrie, Anne Maree Mackenzie, Qing Liu, Pushkar Shrestha, Peter David Nichols, Susan Irene Ellis Blackburn, Maged Peter Mansour, Stanley Suresh Robert, Dion Matthew Frederick Frampton, Xue-Rong Zhou, Surinder Pal Singh, Craig Christopher Wood
