Zachary Lippman, a plant biologist at Cold Spring Harbor Laboratory, stood among 2 acres of his experimental crops, including some altered with a gene-editing technology called Crispr-Cas9, one of the most ambitious efforts yet to improve on what nature created.

He plucked a tomato, held it up and asked: “Will people eat it?”

That question is rippling through the food industry, where a battle for public opinion is under way even before the new gene-edited foods hit the market.
