植物在其自然栖息地中不断地面临过多的非生物和生物胁迫。适应这种变化需要很大程度的表型可塑性，这主要是由植物的基因组决定的。我们目前还不知道植物如何能够整合众多部分协同/部分拮抗的环境信号，使它们能够在任何给定条件下做出适当的反应。然而，显而易见的是，植物能够以高度动态和时间的方式对其转录组进行广泛的重编程。这种调节反应，导致植物在高度可变的环境中的适应性可塑性，主要是通过各种转录因子（TF）的网络来实现的。WRKY TF是形成这种网络的调节蛋白的大家族（Eulgem和Somssich，2007）。它们参与各种植物过程，但最显著的是应对各种生物和非生物胁迫。在这次更新中，我们将把注意力限制在WRKY TF在植物免疫中的作用上。
Plants constantly face a plethora of abiotic and biotic stresses in their natural habitat. Adapting to such changes requires a great degree of phenotypic plasticity that is mainly determined by the plant’s genome. We currently do not know how plants are able to integrate the multitude of partly synergistic/partly antagonistic environmental signals that enable them to respond properly under any given condition. What has become apparent, however, is that plants are capable of extensive reprogramming of their transcriptome in a highly dynamic and temporal manner. This regulation in response, leading to adaptive plasticity of plants in highly variable environments, is mainly achieved by enforcement of a network of various transcription factors (TFs). WRKY TFs are a large family of regulatory proteins forming such a network (Eulgem and Somssich, 2007). They are involved in various plant processes but most notably in coping with diverse biotic and abiotic stresses. In this update, we will restrict our attention to the role of WRKY TFs in plant immunity.
