Soybean is the important crop with abundant protein, vegetable oil, and several phytochemicals. With such predominant values, soybean is cultivated with a long history. However, flooding and drought stresses exert deleterious effects on soybean growth. The present review summarizes the morphological changes and affected events in soybean exposed to such extreme-water conditions. Sensitive organ in stressed soybean at different-developmental stages is presented based on protein profiles. Protein quality control and calcium homeostasis in the endoplasmic reticulum are discussed in soybean under both stresses. In addition, the way of calcium homeostasis in mediating protein folding and energy metabolism is addressed. Finally, stress response to flooding and drought is systematically demonstrated. This review concludes the recent findings of plant response to flooding and drought stresses in soybean employed proteomic approaches.
Soybean is considered as traditional-health food because of nutritional elements and pharmacological values. Flooding and drought exert deleterious effects to soybean growth. Proteomic approaches have been employed to elucidate stress response in soybean exposed to flooding and drought stresses. In this review, stress response is presented on organ-specific manner in the early-stage plant and soybean seedling exposed to combined stresses. The endoplasmic reticulum (ER) stress is induced by both stresses; and stress-response in the ER is addressed in the root tip of early-stage soybean. Moreover, calcium-response processes in stressed plant are described in the ER and in the cytosol. Additionally, stress-dependent response was discussed in flooded and drought-stressed plant. This review depicts stress response in the sensitive organ of stressed soybean and forms the basis to develop molecular markers related to plant defense under flooding and drought stresses.
大豆是一种重要的作物，含有丰富的蛋白质、植物油和几种植物化学物质。由于具有如此显著的价值，大豆的种植历史悠久。然而，洪水和干旱胁迫对大豆的生长会产生有害影响。本综述总结了暴露在这种极端水条件下的大豆的形态变化和受影响的事件。根据蛋白质图谱，提出了不同发育阶段受胁迫大豆的敏感器官。讨论了内质网中蛋白质质量控制和钙动态平衡在大豆中的作用。此外，还探讨了钙动态平衡在介导蛋白质折叠和能量代谢中的作用。最后，系统地展示了大豆对洪水和干旱的应激反应。本综述总结了采用蛋白质组学方法研究大豆对洪水和干旱胁迫的反应的最新发现。
大豆因其营养元素和药理价值而被视为传统的健康食品。洪水和干旱对大豆的生长会产生有害影响。蛋白质组学方法已被用于阐明暴露于洪水和干旱胁迫下的大豆的应激反应。在本综述中，以早期植物和大豆幼苗在受到综合胁迫时的器官特异性方式展示了应激反应。内质网（ER）应激是由这两种胁迫引起的；并在早期大豆根尖中探讨了 ER 中的应激反应。此外，还描述了胁迫植物中钙反应过程在 ER 和细胞质中的作用。此外，还讨论了受胁迫植物中的应激依赖性反应。本综述描述了受胁迫大豆敏感器官的应激反应，为在洪水和干旱胁迫下开发与植物防御相关的分子标记奠定了基础。
