Crop loss due to soil salinization is an increasing threat to agriculture worldwide. This review provides an overview of cellular and physiological mechanisms in plant responses to salt. We place cellular responses in a time- and tissue-dependent context in order to link them to observed phases in growth rate that occur in response to stress. Recent advances in phenotyping can now functionally or genetically link cellular signaling responses, ion transport, water management, and gene expression to growth, development, and survival. Halophytes, which are naturally salt-tolerant plants, are highlighted as success stories to learn from. We emphasize that () filling the major knowledge gaps in salt-induced signaling pathways, () increasing the spatial and temporal resolution of our knowledge of salt stress responses, () discovering and considering crop-specific responses, and () including halophytes in our comparative studies are all essential in order to take our approaches to increasing crop yields in saline soils to the next level.
由于土壤盐渍化导致的作物减产是全球农业面临的日益严重的威胁。本综述概述了植物对盐胁迫响应的细胞和生理机制。我们将细胞响应置于时间和组织依赖的背景下，以便将它们与观察到的响应胁迫时的生长速率的阶段联系起来。现在，表型分析的最新进展可以在功能或遗传上将细胞信号响应、离子转运、水管理和基因表达与生长、发育和生存联系起来。耐盐植物（即天然耐盐植物）被作为成功案例加以强调。我们强调，填补盐诱导信号通路中的主要知识空白、提高我们对盐胁迫响应的时空分辨率、发现和考虑作物特异性响应以及将盐生植物纳入我们的比较研究中，对于将我们在盐渍土壤中提高作物产量的方法提升到一个新的水平是至关重要的。
