Higher plants not only provide human beings renewable food, building materials and energy, but also play the most important role in keeping a stable environment on earth. Plants differ from animals in many aspects, but the important is that plants are more easily influenced by environment than animals. Plants have a series of fine mechanisms for responding to environmental changes, which has been established during their long-period evolution and artificial domestication. The machinery related to molecular biology is the most important basis. The elucidation of it will extremely and purposefully promote the sustainable utilization of plant resources and make the best use of its current potential under different scales. This molecular mechanism at least includes drought signal recognition (input), signal transduction (many cascade biochemical reactions are involved in this process), signal output, signal responses and phenotype realization, which is a multi-dimension network system and contains many levels of gene expression and regulation. We will focus on the physiological and molecular adaptive machinery of plants under soil water stress and draw a possible blueprint for it. Meanwhile, the issues and perspectives are also discussed. We conclude that biological measures is the basic solution to solving various types of issues in relation to sustainable development and the plant measures is the eventual way.
高等植物不仅为人类提供可再生的食物、建筑材料和能源，而且在维持地球稳定环境方面发挥着最重要的作用。植物在许多方面与动物不同，但重要的是，植物比动物更容易受到环境的影响。植物有一系列精细的机制来应对环境变化，这些机制是在它们长期的进化和人工驯化过程中建立起来的。与分子生物学相关的机制是最重要的基础。对其的阐明将在不同尺度上极其有针对性地促进植物资源的可持续利用，并充分发挥其现有潜力。该分子机制至少包括干旱信号识别（输入）、信号转导（该过程涉及许多级联生化反应）、信号输出、信号响应和表型实现，这是一个多维网络系统，包含多个层次的基因表达和调控。我们将重点关注植物在土壤水分胁迫下的生理和分子适应机制，并为此绘制一个可能的蓝图。同时，还讨论了相关的问题和观点。我们的结论是，生物措施是解决与可持续发展有关的各种问题的基本解决方案，植物措施是最终途径。
