The effects of ozone on the leaf processes of poplar: A proteomics approach

Abstract : After the industrial revolution of the 1700s and 1800s, and the subsequent industrialization, many pollutants have accumulated in the atmosphere, mainly due to the use of coal and fossil fuels. Besides the primary pollutants such as nitrogen oxides and sulfur oxides, secondary oxides such as ozone started to accumulate. Nowadays, ozone is the third gas involved in global climate change, but is also a major health risk for humans, and induces considerable damage to vegetation. Starting in the 50s, ozone research was based on targeted studies. Nowadays, with the advent of global techniques such as transcriptomics and proteomics, new results can be produced in an unbiased way. In the thesis presented here, a proteomic study of the effects of ozone on poplar leaf processes was carried out. With the help of this technique, complemented with biochemical and physiological approaches and with morphological observations, it was possible to confirm previous results, but also to elaborate new hypotheses concerning the effects of ozone on poplar leaf metabolism. In parallel, studying the stress also allowed to clarify some of the changes that occur in metabolism during leaf development, under stress conditions and under control conditions. In this document, the procedures, results and conclusions obtained during this study are presented in detail
