USDA-APHIS determines Yield10’s omega-3 camelina varieties may be planted, bred in US


Yield10 Bioscience Inc. announced March 21 that the USDA Animal and Plant Health Inspection Service’s Biotechnology Regulatory Services has determined that Yield10’s camelina varieties developed using genetic engineering to produce omega-3 fatty acids are not subject to the regulations under 7 CFR part 340, and may be grown and bred in the United States.


The global markets for omega-3 fatty acids include aquafeed used for salmon and trout farming, pet feed, baby formula, nutraceutical and pharmaceutical products.


Most omega-3 fatty acids are produced from ocean-caught fish.


Production constraints and supply volatility of traditional fish-oil sources are creating gaps in supply and driving the growing demand for new sources of omega-3.


Utilizing camelina as a land-based production platform has the potential to provide a new, reliable supply for omega-3 fatty acids.


Yield10’s submissions along with the USDA-APHIS BRS responses are posted on the USDA’s website.


“This regulatory milestone represents a critical step for enabling the ramp-up of camelina planting to commercial scale in the U.S for producing omega-3 oil for key markets including aquafeed and human nutrition,” said Kristi Snell, chief science officer of Yield10 Bioscience. “In 2024, we plan to focus on executing our development program, building seed inventory in anticipation of commercial-scale planting, and engaging with potential commercial partners to enable commercial sale of omega-3 oil and meal in target markets. Use of omega-3 oil in target markets may still be subject to regulation from other regulatory authorities in target geographies.” 


In 2023, Yield10 submitted two requests for regulatory status review (RSR) to the BRS under the Sustainable, Ecological, Consistent, Uniform, Responsible, Efficient rule. 


An RSR filed in July 2023 covers camelina engineered to produce eicosapentaenoic acid (EPA) where the engineered omega-3 camelina produces oil containing approximately 16 percent to 20 percent EPA.


An RSR filed in December 2023 covers producing both EPA and docosahexaenoic acid (DHA) in which the engineered omega-3 camelina produces oil containing approximately 10 percent EPA and 10 percent DHA, closely resembling the omega-3 EPA/DHA fatty-acid profile of northern hemisphere fish oil.


The responses from USDA-APHIS indicate that the agency does not consider the modified camelina plants to be an increased plant pest risk as compared to unmodified camelina and are therefore not subject to regulation under 7 CFR part 340 regulations.



Currently, the primary source of the essential fatty acids EPA and DHA is ocean-caught fish, where omega-3 oil produced from anchovy harvest serves as the industry benchmark.


Producing omega-3 fatty acids in camelina represents a potential way to enable a reliable supply of high-quality omega-3 oils to meet the global demand for EPA and DHA.


In 2020, Yield10 signed a collaboration agreement with Rothamsted to support Rothamsted’s flagship program to develop omega-3 oils in camelina.


As part of the collaboration agreement, the company received an exclusive option to sign a global, exclusive license agreement for the technology.


In October 2023, Yield10 announced it had exercised this option and plans to finalize the global commercial license with Rothamsted.


Subsequently, Yield10 and BioMar Group, a global aquafeed producer, signed a letter of intent to form a long-term partnership to commercialize a camelina crop containing enriched levels of EPA and DHA equal to fish oil.


In 2024, Yield10 plans to work with BioMar Group toward the signing of a partnership agreement.


In addition, Yield10 plans to continue field testing and seed scale-up activities for its engineered omega-3 camelina varieties to ramp-up seed inventory for future planting as well as to produce omega-3 oil for use in business-development activities.


Yield10 is also engineering second-generation omega-3 camelina lines with herbicide-tolerance traits to enable weed control in large-scale commercial planting of the crop.
