Ascorbate (Asc), commonly known as vitamin C, is a vital molecule for plant growth, development, and stress resilience. It is also known to play a crucial role in various physiological processes, including photosynthesis, cell division, and differentiation. This article thoroughly explores the processes governing the metabolism of Asc in plants and its roles in physiological functions. It lays down a robust theoretical groundwork for delving into Asc production, transportation, functions, and its potential applications in stress alleviation and horticulture. Furthermore, recent studies indicate that Asc plays a role in regulating fruit development and affecting postharvest storage characteristics, thereby influencing fruit ripening and resilience to stress. Hence, there is a growing importance in studying the synthesis and utilization of Asc in plants. Although the critical role of Asc in controlling plant redox signals has been extensively studied, the precise mechanisms by which it manages cellular redox homeostasis to maintain the equilibrium between reactive oxygen scavenging and cell redox signaling remain elusive. This gap in knowledge presents fresh opportunities to explore how the production of Asc in plants is regulated and how plants react to environmental stressors. Furthermore, this article delves into the potential for a comprehensive investigation into the essential function of Asc in fruits, the development of Asc-rich fruits, and the enhancement of postharvest storage properties.

抗坏血酸作为植物发育的多功能调节剂：对提高作物生产力、质量和采后储存的实际意义


抗坏血酸 （Asc），俗称维生素 C，是植物生长、发育和抗逆性的重要分子。众所周知，它在各种生理过程中起着至关重要的作用，包括光合作用、细胞分裂和分化。本文深入探讨了植物中 Asc 代谢的控制过程及其在生理功能中的作用。它为深入研究 Asc 的生产、运输、功能及其在缓解压力和园艺中的潜在应用奠定了坚实的理论基础。此外，最近的研究表明，Asc 在调节果实发育和影响采后储存特性方面发挥作用，从而影响果实成熟和对压力的恢复力。因此，研究植物中 Asc 的合成和利用变得越来越重要。尽管 Asc 在控制植物氧化还原信号中的关键作用已得到广泛研究，但它管理细胞氧化还原稳态以维持活性氧清除和细胞氧化还原信号之间平衡的确切机制仍然难以捉摸。这种知识差距为探索植物中 Asc 的产生如何受到调节以及植物如何对环境压力源做出反应提供了新的机会。此外，本文深入探讨了全面研究 Asc 在水果中的基本功能、富含 Asc 的水果的开发以及增强采后储存特性的潜力。
