Different redox-active compounds, such as ascorbate, glutathione, NAD(P)H and proteins from the thioredoxin superfamily, contribute to the general redox homeostasis in the plant cell. The myriad of interactions between redox-active compounds, and the effect of environmental parameters on them, has been encapsulated in the concept of a cellular redox state. This concept has facilitated progress in understanding stress signalling and defence in plants. However, despite the proven usefulness of the concept of a redox state, there is no single, operational definition that allows for quantitative analysis and hypothesis testing.
不同的氧化还原活性化合物，如抗坏血酸、谷胱甘肽、NAD(P)H 和硫氧还蛋白超家族的蛋白质，有助于植物细胞的总体氧化还原稳态。氧化还原活性化合物之间的无数相互作用，以及环境参数对它们的影响，都包含在细胞氧化还原状态的概念中。这个概念促进了对植物胁迫信号和防御的理解。然而，尽管氧化还原状态的概念已经被证明是有用的，但没有一个单一的、可操作的定义可以进行定量分析和假设检验。
