The last decades have witnessed a rapid development of noninvasive plant phenotyping, capable of detecting plant stress scale levels from the subcellular to the whole population scale. However, even with such a broad range, most phenotyping objects are often just concerned with leaves. This review offers a unique perspective of noninvasive plant stress phenotyping from a multi-organ view. First, plant sensing and responding to abiotic stress from the diverse vegetative organs (leaves, stems, and roots) and the interplays between these vital components are analyzed. Then, the corresponding noninvasive optical phenotyping techniques are also provided, which can prompt the practical implementation of appropriate noninvasive phenotyping techniques for each organ. Furthermore, we explore methods for analyzing compound stress situations, as field conditions frequently encompass multiple abiotic stressors. Thus, our work goes beyond the conventional approach of focusing solely on individual plant organs. The novel insights of the multi-organ, noninvasive phenotyping study provide a reference for testing hypotheses concerning the intricate dynamics of plant stress responses, as well as the potential interactive effects among various stressors.
在过去几十年中，非侵入性植物表型分析发展迅速，能够检测从亚细胞水平到整个群体水平的植物胁迫程度。然而，即便范围如此广泛，大多数表型分析对象通常仅关注叶片。本综述从多器官视角提供了非侵入性植物胁迫表型分析的独特观点。首先，分析了植物从不同营养器官（叶、茎和根）感知和响应非生物胁迫以及这些重要组成部分之间的相互作用。然后，还提供了相应的非侵入性光学表型分析技术，这可以推动针对每个器官的适当非侵入性表型分析技术的实际应用。此外，我们探索了分析复合胁迫情况的方法，因为田间条件常常包含多种非生物胁迫源。因此，我们的工作超越了仅关注单个植物器官的传统方法。多器官、非侵入性表型分析研究的新颖见解为检验有关植物胁迫反应复杂动态以及各种胁迫源之间潜在相互作用的假设提供了参考。
