Nitro-oleic acid triggers ROS production via NADPH oxidase activation in plants: A pharmacological approach.

ABSTRACT: Nitrated fatty acids (NO₂-FAs) are important signaling molecules in mammals. NO₂-FAs are formed by the addition reaction of nitric oxide- and nitrite-derived nitrogen dioxide with unsaturated fatty acid double bonds. The study of NO₂-FAs in plant systems constitutes an interesting and emerging area. The presence of NO₂-FA has been reported in olives, peas, rice and Arabidopsis. To gain a better understanding of the role of NO₂-FA on plant physiology, we analyzed the effects of exogenous application of nitro-oleic acid (NO₂-OA). In tomato cell suspensions we found that NO₂-OA induced reactive oxygen species (ROS) production in a dose-dependent manner via activation of NADPH oxidases, a mechanism that requires calci
