Changing the genetic makeup of trees could supercharge their ability to suck up carbon dioxide. But are forests of frankentrees really a good idea?
levels.) Living Carbon’s eventual business model will be to plant its genetically engineered trees on land leased from private landowners, then give those landowners a share of the money earned by selling carbon credits earned against the growth of the trees.
Tao and his colleagues grew the genetically engineered poplars for 21 weeks in a lab before harvesting and weighing them to see how much biomass they’d accumulated. The best-performing seedling had 53 percent more above-ground biomass than non-edited plants. Tests also showed that the edited plants took up more carbon than their non-edited cousins, an indication that these plants had a higher rate of photosynthesis.
Soon this will be put to the test. Living Carbon has already planted 468 of its photosynthesis-enhanced trees in central Oregon, part of a field trial it’s running with Oregon State University. The company will analyze how quickly the trees grow over longer periods of time and also how they perform in different environments.
But some plant scientists think there’s a simpler path to making a better tree: cultivating them the old-fashioned way. Humans have been breeding better crops for thousands of years, says Richard Buggs, an evolutionary biologist who studies plant health at Kew Gardens in London. “I’m totally in agreement with that core premise that we need trees that are more productive and fix carbon faster.
