Multifeature analyses of vascular cambial cells reveal longevity mechanisms in old Ginkgo biloba tre

Aging is a universal property of multicellular organisms. Although some
tree species can live for centuries or millennia, the molecular and
metabolic mechanisms underlying their longevity are unclear. To address
this, we investigated age-related changes in the vascular cambium from
15- to 667-y-old Ginkgo biloba trees. The ring width decreased
sharply during the first 100 to 200 y, with only a slight change after
200 y of age, accompanied by decreasing numbers of cambial cell layers.
