Had the plants survived long enough to flower, they would have betrayed a distinctly yellow tint in the otherwise white part of the grain. That is because the rice is endowed with a gene from corn and another from a bacterium, making it the only variety in existence to produce beta carotene, the source of vitamin A. Its developers call it “Golden Rice.”
The concerns voiced by the participants in the Aug. 8 act of vandalism — that Golden Rice could pose unforeseen risks to human health and the environment, that it would ultimately profit big agrochemical companies — are a familiar refrain in the long-running controversy over the merits of genetically engineered crops. They are driving the desire among some Americans for mandatory “G.M.O.” labels on food with ingredients made from crops whose DNA has been altered in a laboratory. And they have motivated similar attacks on trials of other genetically modified crops in recent years: grapes designed to fight off a deadly virus in France, wheat designed to have a lower glycemic index in Australia, sugar beets in Oregon designed to tolerate a herbicide, to name a few.
“We do not want our people, especially our children, to be used in these experiments,” a farmer who was a leader of the protest told the Philippine newspaper Remate.
But Golden Rice, which appeared on the cover of Time Magazine in 2000 before it was quite ready for prime time, is unlike any of the genetically engineered crops in wide use today, designed to either withstand herbicides sold by Monsanto and other chemical companies or resist insect attacks, with benefits for farmers but not directly for consumers.
And a looming decision by the Philippine government about whether to allow Golden Rice to be grown beyond its four remaining field trials has added a new dimension to the debate over the technology’s merits.
Not owned by any company, Golden Rice is being developed by a nonprofit group called the International Rice Research Institute with the aim of providing a new source of vitamin A to people both in the Philippines, where most households get most of their calories from rice, and eventually in many other places in a world where rice is eaten every day by half the population. Lack of the vital nutrient causes blindness in a quarter-million to a half-million children each year. It affects millions of people in Asia and Africa and so weakens the immune system that some two million die each year of diseases they would otherwise survive.
The destruction of the field trial, and the reasons given for it, touched a nerve among scientists around the world, spurring them to counter assertions of the technology’s health and environmental risks. On a petition supporting Golden Rice circulated among scientists and signed by several thousand, many vented a simmering frustration with activist organizations like Greenpeace, which they see as playing on misplaced fears of genetic engineering in both the developing and the developed worlds. Some took to other channels to convey to American foodies and Filipino farmers alike the broad scientific consensusthat G.M.O.’s are not intrinsically more risky than other crops and can be reliably tested.
At stake, they say, is not just the future of biofortified rice but also a rational means to evaluate a technology whose potential to improve nutrition in developing countries, and developed ones, may otherwise go unrealized.
“There’s so much misinformation floating around about G.M.O.’s that is taken as fact by people,” said Michael D. Purugganan, a professor of genomics and biology and the dean for science at New York University, who sought to calm health-risk concerns in a primer on GMA News Online, a media outlet in the Philippines: “The genes they inserted to make the vitamin are not some weird manufactured material,” he wrote, “but are also found in squash, carrots and melons.”
Mr. Purugganan, who studies plant evolution, does not work on genetically engineered crops, and until recently had not participated in the public debates over the risks and benefits of G.M.O.’s. But having been raised in a middle-class family in Manila, he felt compelled to weigh in on Golden Rice. “A lot of the criticism of G.M.O.’s in the Western world suffers from a lack of understanding of how really dire the situation is in developing countries,” he said.
Some proponents of G.M.O.’s say that more critical questions, like where biotechnology should fall as a priority in the efforts to address the root causes of hunger and malnutrition and how to prevent a few companies from controlling it, would be easier to address were they not lumped together with unfounded fears by those who oppose G.M.O.’s.
“It is long past time for scientists to stand up and shout, ‘No more lies — no more fear-mongering,’ ” said Nina V. Fedoroff, a professor at the King Abdullah University of Science and Technology in Saudi Arabia and a former science adviser to the American secretary of state, who helped spearhead the petition. “We’re talking about saving millions of lives here.”
Precisely because of its seemingly high-minded purpose, Golden Rice has drawn suspicion from biotechnology skeptics beyond the demonstrators who forced their way into the field trial. Many countries ban the cultivation of all genetically modified crops, and after the rice’s media debut early in the last decade, Vandana Shiva, an Indian environmentalist, called it a “Trojan horse” whose purpose was to gain public support for all manner of genetically modified crops that would benefit multinational corporations at the expense of poor farmers and consumers.
In a 2001 article, “The Great Yellow Hype,” the author Michael Pollan, a critic of industrial agriculture, suggested that it might have been developed to “win an argument rather than solve a public-health problem.” He cited biotechnology industry advertisements that featured the virtues of the rice, which at the time had to be ingested in large quantities to deliver a meaningful dose of vitamin A.
But the rice has since been retooled: a bowl now provides 60 percent of the daily requirement of vitamin A for healthy children. And Gerard Barry, the Golden Rice project leader at the International Rice Research Institute — and, it must be said, a former senior scientist and executive at Monsanto — suggests that attempts to discredit Golden Rice discount the suffering it could alleviate if successful. He said, too, that critics who suggest encouraging poor families to simply eat fruits and vegetables that contain beta carotene disregard the expense and logistical difficulties that would thwart such efforts.
