Yield10 Bioscience to Report Results Showing that Trait C4001
Produces Significant Increases in Plant Yield
---CSO Dr. Kristi Snell to Present Results Today at the Plant Biology 2017 Conference

WOBURN, Mass. - June 27, 2017 - Yield10 Bioscience, Inc. (NASDAQ:YTEN) announced that the Company’s novel C4001 trait, a global regulatory gene or transcription factor, has been shown to significantly increase plant biomass yield in switchgrass. Yield10’s Chief Science Officer Kristi Snell, Ph.D., will be presenting data today at the Plant Biology 2017 Conference. The C4001 trait was identified using Yield10’s T3 Platform, a novel method for gene discovery.

At the conference, Dr. Snell will describe the performance of the C4001 trait in switchgrass plants, a model plant system that Yield10 has used for gene discovery and evaluation, as well as the effect of expression of C4001 on photosynthesis. Switchgrass plants expressing C4001 had significantly more aboveground biomass (75-100% increase in dry weight) as compared to controls and more root biomass (85-145% increase in dry weight) as compared to controls. The C4001 trait in switchgrass plants increased a key measure of photosynthetic efficiency, the electron transport rate, by approximately 75%. Yield10 researchers challenged the C4001 plants by engineering a novel carbon sink, the production of a biopolymer that typically reduces plant yield when expressed and accumulated at high levels in plants. Expression of C4001 in biopolymer producing plants partially restored biomass production, yielding healthier (size, weight) plants as compared to control plants, while producing the same amount of biopolymer. This novel approach of challenging the plant with a carbon sink that stresses the plant and reduces its biomass allows Yield10 researchers to further evaluate and understand the performance of novel yield traits and their ability to increase carbon fixation rates in plants. Dr. Snell will also discuss the use of the T3 Platform to identify downstream transcription factors and metabolic genes controlled by C4001 that are targets for genome editing to increase crop yield.

“The T3 Platform and switchgrass system developed by our team provides a unique tool for the discovery and characterization of yield trait genes,” commented Dr. Snell. “The results in switchgrass reported today underscore the unique insights we’ve gained as we have engineered improvements to photosynthetic efficiency into plants. Based on this fundamental research tool, we have identified novel yield traits and genome editing targets having the potential to produce step-changes in plant productivity.”

“As a next step, we are planning to evaluate C4001-like traits in forage crops and major commercial crops including corn and rice. We are currently evaluating the trait in rice in greenhouse studies, where we are seeing evidence of increased biomass and are awaiting results from ongoing research to determine the impact on seed yield,” commented Dr. Snell.

The Plant Biology 2017 Conference is the annual meeting of the American Society of Plant Biologists being held June 24-28 in Honolulu, Hawaii. Dr. Snell will present in a session entitled “Applied Plant Biology” which is scheduled for today at 1:30 pm (HAST local time or 7:30 pm ET).
