植物中普遍存在的抗病机制有两种，即过敏反应(HR)和系统获得性抗性(SAR)。
There are two types of mechanism of plant disease resistance, hypersensitive response (HR) and systemic acquired resistance (SAR).
一旦肿瘤对特定的化学治疗剂具有获得性抗性之后，通常就会观察到其对其它结构类似的试剂的间接抗性。
Once a tumor has acquired resistance to a specific chemotherapeutic agent, it is common to observe collateral resistance to other structurally similar agents.
转拟南芥npr 1基因可使植物广泛增强疾病抗性，尤其是系统获得性抗性(SAR)，刺激未感染植物引发防御反应。
The Arabidopsis NPR1 gene controls the onset of systemic acquired resistance (SAR), a plant immunity that is often activated after a local infection.
拟南芥npr 1基因是植物产生系统获得性抗的关键调节基因，参与对白粉病的抗性反应。
The NPR1 gene in arabidopsis plays an important role in activating various plant defensive responses, including expression of the pathogenesis-related genes and systemic acquired resistance.
