Wheat genes could help revive American chestnut

Blight has made the American chestnut, once “the dominant tree in the canopy,” a rare sight in the forests of the East. Now some researchers hope to save the tree by giving it a last-ditch genetic modification, reports David Biello for Scientific American’s 60-Second Science podcast.

But the source of the genes is somewhat surprising: they come from wheat. A single gene from wheat gives the chestnut the power to detoxify the acid the blight produces to destroy tree flesh.

Biello explains:

A few of the hybrid chestnuts have been planted in the wild from New Jersey to Virginia. And test plots of the genetically foritified trees have shown promising results. Some environmentalists worry about genetically modified organisms. But a bit of genetic tweaking, whether by crossbreeding or gene insertion, looks like the only way to restore the chestnut to its former glory.

The newer effort would make the American chestnut a GMO. But Tamar Haspel for The Washington Post argues that that shouldn’t put people off. She says the effort is “everything that the GMOs now in our food supply are not. It wasn’t created for personal profit or for the benefit of corporations or farmers. It contributes to a wholesome, healthful diet. And it’s intended solely for the public good.”
