GMOs -- genetically modified organisms -- are not exactly a controversial subject at the Ag Innovation Showcase.
The three-day annual event is the place where theagricultureindustry comes together to talk about new trends and startups to present to potential investors.
Yet this week at the seventh annual showcase at the DonaldDanforthPlant Science Center in St. Louis, there was also discussion around how people outside of agriculture view the technology. The auditorium was packed for a panel discussion called "Transparency Without Prejudice--Bridging theGMODivide."
"In the past people trusted that companies had the best interest of the environment, the ecosystem, human health, but that benevolence is lost," said moderator Han Chen, CEO of biotech startupZeaKal. "Why do you think we lost that? And how do you think we can restore it?"
The answers varied from getting more people interested in science to focusing on the positives ofGMO.
After the discussion panelist AnthonyZolezzitold St. Louis Public Radio that talking about science will have little impact on people’s feelings about biotechnology. An investor in the organic industry,Zolezzisaid the way to change minds is to change the conversation.
"Every word that comes along biotech should be 'for mankind,' 'for the benefit of humans,' 'for the next three billion,'" he said.
That three billion figure came up a lot at the Ag Innovation Showcase.
Scientists estimate the world’s population will grow with an additional 3 billion by 2050. In order to feed that many people, panelist GeoffKneen, an R&D manager at BayerCropScience, said technology must stop being demonized.
"I think we need to recognize what we’ve experienced in the past and stand up for the benefits of these technologies in the future,"Kneensaid.
New Technology
Thingsare evolving quickly in agricultural science.
At Monsanto, the seed giant just across the street from the Donald DanforthPlant Science Center, the company’s newest platform includes something called microbials.
"The soil environment around a plant is already teaming with microbes," said Steve Padgette, vice president of R&D Investment Strategy at Monsanto.
Those microbes already are helping plants fend off things like fungus and bacteria. Monsanto formed theBioAgAlliance with Danish companyNovozymesin 2014 to begin selling microbe-coated seeds.
"What we’re trying do is understand the plants and the soil environment well enough so that we could augment the natural population of microbes with additional microbes to help the plant grow better and ultimately give better yield," he said.
Padgette said what are known asbiologicals in the ag industry brought in about $2.9 billion globally in 2014. He said about two-thirds of that came frommicrobials, but another important area within biologicals is RNA technology.
The technology makes use of RNA interference, also calledRNAi. It’s a biological process where RNA molecules inhibit gene expression. The goal is to allow farmers to apply RNA directly onto crops to help prevent pests and disease.
St. Louis-based start-up Apse is working on how to make topical RNA application less expensive and more effective. CEO JohnKillmersaid the new technology is still a few years from market. But so far, he says it’s being embraced even in the organic farming world.
"Suppliers to the organic farming industry call me and say 'What are you waiting for? When are you going to come out with this?'" Killmersaid, "... because they’re enamored with thenon-GMOcomponent of this."
Killmer spent several years with Monsanto, including five years as president of Monsanto China. He said the current reception to RNA technology doesn’t mean there won’t be a backlash in the future.
"It’snon-GMOtechnology, it has nothing to do with genetic modification, but the actual facts of the situation sometimes aren’t as important as the emotion and perception," he said.
Science based on nature
The emotional reaction toGMOsis something Jim Carrington sees as unfortunate but understandable. The president of the DonaldDanforthPlant Science Center, Carrington said it’s not just aGMOissue.
"Food is a very emotional, very sensitive issue for much of our population," he said. "When you have new technology it can be scary because it’s not well understood by most people."
He saidGMOsremain a part of the solution for sustainable agriculture, especially because alternatives aren’t always available. But as a plant scientist himself, Carrington is especially excited about the new technologies that are based on how nature controls pests and disease.
"In agriculture we’ve tipped the balance a little off of what nature has provided us in the past," he said. "With thebiologicalsand RNA and taking advantage of natural mechanisms through science, the goal is tointrogressa little bit more nature back but retain productivity."
Productivity, of course, is key as plant scientists try to figure out how to feed an additional three billion people.
