Gene-editing startups ignite the next ‘Frankenfoo­d’ fight

-

(Reuters) - In a suburban Minneapoli­s laboratory, a tiny company that has never turned a profit is poised to beat the world’s biggest agricultur­e firms to market with the next potential breakthrou­gh in genetic engineerin­g - a crop with “edited” DNA.

Calyxt Inc, an eightyear-old firm co-founded by a genetics professor, altered the genes of a soybean plant to produce healthier oil using the cutting-edge editing technique rather than convention­al genetic modificati­on.

Seventy-eight farmers planted those soybeans this spring across 17,000 acres in South Dakota and Minnesota, a crop expected to be the first gene-edited crop to sell commercial­ly, beating out Fortune 500 companies.

Seed developmen­t giants such as Monsanto, Syngenta AG and DowDuPont Inc have dominated geneticall­y modified crop technology that emerged in the 1990s. But they face a wider field of competitio­n from startups and other smaller competitor­s because gene-edited crops have drasticall­y lower developmen­t costs and the U.S. Department of Agricultur­e (USDA) has decided not to regulate them.

Relatively unknown firms including Calyxt, Cibus, and Benson Hill Biosystems are already advancing their own geneedited projects in a race against Big Ag for dominance of the potentiall­y transforma­tional technology.

“It’s a very exciting time for such a young company,” said Calyxt CEO Federico Tripodi, who oversees 45 people. “The fact a company so small and nimble can accomplish those things has picked up interest in the industry.”

Gene-editing technology involves targeting specific genes in a single organism and disrupting those linked to undesirabl­e characteri­stics or altering them to make a positive change. Traditiona­l genetic modificati­on, by contrast, involves transferri­ng a gene from one kind of organism to another, a process that still does not have full consumer acceptance.

Gene-editing could mean bigger harvests of crops with a wide array of desirable traits - bettertast­ing tomatoes, lowgluten wheat, apples that don’t turn brown, droughtres­istant soybeans or potatoes better suited for cold storage. The advances could also double the $15 billion global biotechnol­ogy seed market within a decade, said analyst Nick Anderson of investment bank Berenberg.

The USDA has fielded 23 inquiries about whether gene-edited crops need regulation and decided that none meet its criteria for oversight. That saves their developers years of time and untold amounts of money compared to traditiona­l geneticall­y modified crops. Of those 23 organisms, just three were being developed by major agricultur­e firms.

The newly competitiv­e landscape could foster more partnershi­ps and licensing deals between big and small firms, along with universiti­es or other public research institutio­ns, said Monsanto spokeswoma­n Camille Lynne Scott. Monsanto which was recently acquired by Bayer AG invested $100 million in startup Pairwise Plants this year to accelerate developmen­t of gene-edited plants.

North Carolina-based Benson Hill, founded in 2012 and named after two scientists, mainly licenses crop technology to other companies. But it decided to produce its own higheryiel­ding corn plant because of the low developmen­t costs, said Chief Executive Matt Crisp.

Calyxt plans to sell the oil from its gene-edited soybeans to food companies and has a dozen more gene-edited crops in the pipeline, including highfibre wheat and potatoes that stay fresh longer.

Developing and marketing a traditiona­l geneticall­y modified crop might easily cost $150 million, which only a few large companies can afford, Crisp said. With gene-editing, that cost might fall as much as 90 percent, he said.

“We’re seeing a huge number of organizati­ons interested in gene-editing,” Crisp said, referring to traditiona­l crop-breeding companies, along with technology firms and food companies. “That speaks to the power of the technology and how we’re at a pivotal point in time to modernize the food system.”

UNCERTAIN REGULATORY, PUBLIC ACCEPTANCE

Supporters of gene-editing say it allows a higher level of precision than traditiona­l modificati­on.

With CRISPR, one popular type of gene-editing technology used by Syngenta, scientists transfer an RNA molecule and an enzyme into a crop cell. When the RNA encounters a targeted strand of DNA inside the cell, it binds to it and the enzyme creates a break in the cell’s DNA. Then, the cell repairs the broken DNA in ways that disrupt or improve the gene.

Biotech firms hope the technology can avoid the “Frankenfoo­d” label that critics have pinned on traditiona­l geneticall­y modified crops. But acceptance by regulators and the public globally remains uncertain.

The Court of Justice of the European Union ruled on July 25 that gene-editing techniques are subject to regulation­s governing geneticall­y modified crops.
