Tweaks to U.S. Christmas Trees Could Help Them Survive Climate Change

Mounting pressure from extreme weather events and lethal diseases—both exacerbated by climate change—threatens to assail U.S. Christmas tree–growing regions and slash production. To help defend these cherished trees and the farms that raise them, researchers are mapping conifer genomes and exploiting the natural characteristics of species that grow outside the U.S. to identify and breed … Read more
