Long-term depletion of the stratospheric ozone layer contributes to the increase in terrestrial solar ultraviolet-B radiation (UV-B), an environmental change with potentially deleterious consequences for plants. When exposed to elevated UV-B (280-315 nm), plants display a wide variety of physiological and morphological responses. Consequently, determining the molecular bases for acclimation to normal fluence and tolerance of high UV-B are important factors in sustaining plant yield. To better understand the processes of UV-B acclimation, which result in altered plant morphology and physiology, we investigated gene expression in leaves of 5 different white poplar genotypes-clones at high UV-B fluence rate and exposure times.

Abstract
Long-term depletion of the stratospheric ozone layer contributes to the increase in terrestrial solar ultraviolet-B radiation (UV-B), an environmental change with potentially deleterious consequences for plants. When exposed to elevated UV-B (280-315 nm), plants display a wide variety of physiological and morphological responses. Consequently, determining the molecular bases for acclimation to normal fluence and tolerance of high UV-B are important factors in sustaining plant yield. To better understand the processes of UV-B acclimation, which result in altered plant morphology and physiology, we investigated gene expression in leaves of 5 different white poplar genotypes-clones at high UV-B fluence rate and exposure times.File | Dimensione | Formato | |
