Involvement of oxidative burst in systemic signaling for induction of systemic acquired resistance in plants

摘要

Systemic acquired resistance (SAR) in plants is induced by primary induction of local hypersensitive reaction involving oxidative burst (OXB), and salicylic acid (SA) is though to be a systemic signal factor for induction of PR-proteins. However, little is known about systemic signaling mechanisms for SAR induction. We report hear a new aspect of the systemic signaling for SAR that local oxidative burst dispatched a systemic signal, which stimulated the secondary oxidative burst at the other sites prior induction of SAR.
