目前在研究抗性的工作中，我们越来越多的听到非寄主抗性。那什么是非寄主抗性呢？下面这篇综述应该能够让我们有所了解。
Current Understandings on Plant Nonhost Resistance
[size=13.3333px]

Nonhost resistance, a resistance of plant species against all non-adapted pathogens, is considered the most durable and efficient immune system of plants but yet remains elusive. The underlying mechanism of nonhost resistance has been investigated at multiple levels of plant defense for several decades. In this review, we have comprehensively surveyed the latest literature on nonhost resistance in terms of pre-invasion, metabolic defense, pattern-triggered immunity, effector-triggered immunity, defense signaling, and possible application in crop protection. Overall, we summarize the current understanding of nonhost resistance mechanisms. Pre- and post-invasion is not much deviated from the knowledge on host resistance except for a few specific cases. Further insights on the roles of the pattern recognition receptor gene family, multiple interactions between effectors from non-adapted pathogen and plant factors, and plant secondary metabolites in host range determination could expand our knowledge on nonhost resistance and provide efficient tools for the future crop protection using combinational biotechnology approaches.
