American chestnut set for genetically modified revival

The near-extinct American chestnut looks set to make a comeback. Genetically modified trees, which are resistant to a deadly fungus that has decimated the species, have produced the first resistant chestnuts. From these seeds, countless resistant trees could be grown in the wild.

An estimated 4 billion American chestnut trees (Castanea dentata) once covered the US, accounting for a quarter of all US hardwood trees. But in around 1900, a lethal fungus called Cryphonectria parasitica was accidentally imported in chestnut trees from Asia, and by the 1950s it had almost completely wiped out the American chestnut….

All the mai'a maoli and popoulu cooking bananas, which came from the south way back when with the Polynesian settlers, are gone now, because they got Fusarium Wilt.

Don't we want to have tools that will help us preserve our heritage and other valuable plants?
