Regulatory roles of NPR1 in plant defense: regulation and function

Overcoming infection is a struggle that all eukaryotic organisms have to \nface in order to survive and evolve among ubiquitous microorganisms. \nExtensive research on plant defenses has revealed that defense signal \ntransduction pathways form an interconnected network in which the \nsignaling molecules salicylic acid (SA) and jasmonic acid (JA) play key \nroles. Previously, SA and JA signaling pathways have been shown to crosscommunicate. \nCross-talk between defense signaling pathways is thought to \nprovide the plant with a mechanism to activate defenses that are specifically \nactive against the invader encountered.
