Abstract

The plant vacuole, traditionally viewed as a static storage organelle, has recently emerged as a dynamic hub orchestrating signaling, metabolic integration, and stress responses. This review synthesizes recent advances that position the vacuole as a pivotal regulator of plant development and environmental adaptation. We discuss the vacuole's multifaceted roles in ion sequestration, lipid trafficking, mechanosensing, and signal transduction, highlighting its central role in preserving cellular homeostasis. We summarize recent data supporting two distinct forms of vacuolar biogenesis: inheritance from existing organelles and de novo formation. Lastly, we discuss our recent findings that define a vacuolar quality control (VQC) pathway, safeguarding tonoplast integrity during stress. Collectively, these insights redefine our understanding of the vacuole's essential contributions to plant physiology and resilience, advocating for an updated conceptual framework that recognizes the vacuole as a central hub for developmental processes and environmental adaptation.

植物液泡信号、生物发生和质量控制

植物液泡，传统上被认为是一个静态的储存细胞器，最近出现了一个动态枢纽协调信号，代谢整合和胁迫反应。本文综述了液泡作为植物发育和环境适应的关键调节因子的最新研究进展。我们讨论液泡在离子隔离、脂质运输、机械传感和信号转导方面的多方面作用，强调其在保持细胞稳态中的核心作用。我们总结了最近支持两种不同形式的液泡生物发生的数据：现有细胞器的遗传和新生形成。最后，我们讨论了我们最近的研究结果，定义了一个液泡质量控制（VQC）途径，在压力下保护tono质体的完整性。总的来说，这些见解重新定义了我们对液泡对植物生理和恢复力的重要贡献的理解，倡导一个更新的概念框架，承认液泡是发育过程和环境适应的中心枢纽。
