Our data suggest that isoprene exerts its protective mechanism at different levels rather than on a single mode, triggering significant changes in chloroplast protein profiles, but also playing important roles in modulating signaling and hormone pathways and even membrane trafficking. To better understand the molecular mechanism underlying isoprene emission, we performed a LC-MS/MS-based proteomic analysis to explore the changes in protein abundance between WT and EV both under control and moderate water stress conditions. These results indicate that isoprene may exert its protective action at the membrane level, although a similar effect could be obtained if isoprene reacted with ozone before forming active oxygen species. Only ISPS plants were able to maintain the same photosynthesis and fresh weight in water stress and in control condition. Isoprene quenched the amount of H(2)O(2) formed in leaves and reduced lipid peroxidation of cellular membranes caused by ozone. Our aim was to investigate if isoprene-emitting plants displayed a different proteomic profile which may help explain how isoprene protects plants from stresses. In this study we compared the physiological responses and proteomic profile of isoprene-emitting (ISPS) and non-emitting (WT and EV) Arabidopsis thaliana plants subjected to a moderate water stress and in control conditions. Arguably his crowning achievement was the biogenetic isoprene rule, which helped to unravel the. The mechanism of action of isoprene is still under debate. The year 2019 marks the 80th anniversary of the 1939 Nobel Prize in Chemistry awarded to Leopold Ruzicka (1887-1976) for work on higher terpene molecular structures, including the first chemical synthesis of male sex hormones. Isoprene-emitting plants are believed to be better protected against abiotic stresses (i.e. Isoprene is a small lipophilic molecule synthetized at chloroplast level and released into the atmosphere.
