Sponsored by EXPO 2015, it will see the participation of 200 researchers from all over the world

It will be held from 24 26 to June  Patronage of EXPO 2015 the XII international conference entitled "Reactive oxygen and nitrogen species in plants: from model systems to field experimentation", and will see the participation of 200 researchers from all over the world. During the two days of the conference, organized byUniversità Campus Bio-Medico di Roma and from the University of Verona at the Gran Guardia of Verona, the researchers present will discuss some of the most pressing problems in agriculture, such as the identification of plants of agro-food interest capable of better resisting climate change and the attack of pathogens, or the improvement of the nutritional and health value of food plants.

“Plants have a great ability to perceive environmental changes, modifying their metabolism to better adapt. The reactive oxygen species, known by all as harmful molecules, in reality, when produced in low concentrations, are very important signals for the activation of defense responses. Of course, not all species are equally capable of responding adequately to environmental changes – underlines Prof. Laura De Gara, full professor of plant physiology atUniversità Campus Bio-Medico di Roma, co-organizer of the conference - Understanding the activation mechanisms of these responses is also essential, for example, to identify species and varieties that are more productive and resistant to climate change."

The conference will also discuss the resistance of plants to pathogens, one of the main causes of loss of productivity in agriculture and a danger to the healthiness of our foods, just think of the many emergencies of recent years: Xylella for the olive tree, bacterial of kiwi, just to name a few. “Reactive nitrogen species, especially nitric oxide – adds Prof. Delledonne, full professor of Genetics at the University of Verona and co-organizer of the conference -  they play a key role in plant defense responses. We also know very well how the increase of these reactive species can determine variations in the expression of specific genes which make some plants more resistant to pathogens. It is now a question of putting all the information that scientific research has produced in the various parts of the world online to try to identify the best strategies to solve some of the main challenges of our century such as those of a still too present malnutrition and climate change with their negative impact on agriculture.”
