Ozone is considered the most important phytotoxic air pollutant and has well known effects on the metabolism of forest trees. However, the role of leaf development in ozone sensitivity remains unclear. In addition, the photorespiratory pathway has been scarcely investigated under ozone stress. To provide new insights into these issues, young poplar trees (Populus x canescens [Aiton] Sm.) were subjected to 120 ppb of ozone for 35 days in phytotronic chambers. Treated trees displayed foliar symptoms of injury (necrotic spots, chlorosis and precocious leaf senescence) and a reduced stem radial growth. In mature leaves, ozone reduced photosynthesis (A, [phi]PSII) by impairing CO2 fixation, mainly at the level of rubisco (Vcmax and in vitro acti...
