    Abstract

    © 2019 Elsevier Ltd Naranjilla (Solanum quitoense) is an Andean tropical fruit of the solanaceae family with high nutritional value. Its cultivation is gravely affected by the lethal disease produced by Fusarium oxysporum f.sp. quitoense, causing severe economic losses. In this work we studied the possibility of boosting the plants’ natural defenses to the fungus by using plant hormones. Our results show that spraying jasmonic acid or sodium nitroprusside (a NO donor) on naranjilla plantlets before Fusarium inoculation protected them from infection, and elicited strong activation of the corresponding signaling pathway, suggesting a mechanism of defense priming triggered by those compounds.
