Description
Junru Li and co-authors present a 2026 journal article on how climate change may rewrite the genetics of a Chinese flowering dogwood tree. Cornus kousa subspecies chinensis adapts well but spreads slowly, making it a good test case for woody plant responses to a warming world. Its rich internal variation is at stake.
The team gathered leaf samples from three hundred forty-eight trees across twenty-five populations in China. Today's populations hold abundant genetic diversity. Models of future climates for 2060 to 2080, under two emission paths, forecast a sharp squeeze. Over ninety percent of populations would collapse into one shared genetic cluster, homogenizing variation. Sixty-seven DNA markers tied to climate stood out, and almost all linked to average yearly temperature. The authors say temperature is the main selective force, and they offer guidance for conserving the tree's genetic resources.
