Patent number: 11168331Abstract: Provided are plants that express, or overexpress, a pPLAIII? protein. Constitutive or seed-specific expression of pPLAIII? protein in Arabidopsis increases seed oil content, the amount of C20 and C22 fatty acids, and the amount of C56, C58, and C60 triacylglycerols, effectively resulting in significantly higher oil yield per plant. Use of pPLAIII? is therefore an effective biotechnological tool to significantly increase plant yield, including oil, and the amount of high value long chain fatty acids in agricultural and horticultural crops, especially oilseed crops.Type: GrantFiled: March 22, 2019Date of Patent: November 9, 2021Assignees: Donald Danforth Plant Science Center, The Curators of the University of MissouriInventors: Xuemin Wang, Maoyin Li

Patent number: 11053513Abstract: Provided are plants that express, or overexpress, type III G? protein AGG3. Such plants exhibit faster vegetative and reproductive growth, accompanied by an increase in photosynthetic efficiency. Constitutive or seed-specific expression of AGG3 in Camelina increases seed size, seed mass, and seed number per plant by 15-40%, effectively resulting in significantly higher oil yield per plant. AGG3-expressing Camelina plants also exhibit improved stress tolerance. Use of AGG3 is therefore an effective biotechnological tool to dramatically increase stress tolerance and plant yield, including oil, in agricultural and horticultural crops.Type: GrantFiled: July 15, 2014Date of Patent: July 6, 2021Assignee: Donald Danforth Plant Science CenterInventors: Sona Pandey, Swarup Roy Choudhry
