The fight against plant pathogens is of primary importance in agriculture to ensure that quali-quantitative features of fruits and vegetables fit the market requirements. Synthetic products can protect plants against pathogens but they can be toxic or environmental unfriendly, therefore the use of less toxic and less persistent products is highly encouraged. It is known that the electrolysis of water enriched in salts can produce highly reactive oxidative species characterized by a short life span and a potent antimicrobial activity, even at low doses. In the last few years, our group has developed the system for the production of an electrolyzed activated solution (SEA) and has started to study the beneficial antimicrobial effect of SEA on plants infected by different pathogens. Our research also focused on the effects of SEA on plant cells at the molecular level to establish if it can prime plant defences against pathogens. Results will be presented showing that SEA is indeed able to stimulate endogenous defences by activating several pathogen-related genes, both in tobacco and apple plants.

Abstract
The fight against plant pathogens is of primary importance in agriculture to ensure that quali-quantitative features of fruits and vegetables fit the market requirements. Synthetic products can protect plants against pathogens but they can be toxic or environmental unfriendly, therefore the use of less toxic and less persistent products is highly encouraged. It is known that the electrolysis of water enriched in salts can produce highly reactive oxidative species characterized by a short life span and a potent antimicrobial activity, even at low doses. In the last few years, our group has developed the system for the production of an electrolyzed activated solution (SEA) and has started to study the beneficial antimicrobial effect of SEA on plants infected by different pathogens. Our research also focused on the effects of SEA on plant cells at the molecular level to establish if it can prime plant defences against pathogens. Results will be presented showing that SEA is indeed able to stimulate endogenous defences by activating several pathogen-related genes, both in tobacco and apple plants.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
