Autophagy Rep. 2024 Oct 15;3(1):2395731. doi: 10.1080/27694127.2024.2395731. eCollection 2024.
Autophagy is a process of cellular self-eating, which allows organisms to eliminate and recycle unwanted components and damaged organelles to maintain cellular homeostasis. It is an important process in the development of eukaryotic organisms. Autophagy plays a critical role in many physiological processes in plants such as nutrient remobilization, cell death, immunity, and abiotic stress responses. Autophagy thus represents an obvious target for generating resilient crops. During plant development, autophagy is also implicated in the differentiation and maturation of various cell types and plant organs, including root cap cells, tracheary elements, gametes, fruits and seeds. Here, we review our current understanding and recent advances of plant autophagy including insight into autophagy regulation and signaling as well as autophagosome membrane biogenesis. In addition, we describe how autophagy contributes to development, metabolism, biotic and abiotic stress tolerance and where the autophagic field is heading in terms of applied research for crop improvement.
自噬是一种细胞自我吞噬的过程，它使生物体能够清除和回收不需要的成分以及受损的细胞器，以维持细胞内稳态。这是真核生物发育过程中的一个重要过程。自噬在植物的许多生理过程中发挥着关键作用，如营养物质的再分配、细胞死亡、免疫和非生物胁迫反应。因此，自噬是培育抗逆作物的一个明显靶点。在植物发育过程中，自噬也参与了各种细胞类型和植物器官的分化和成熟，包括根冠细胞、管状分子、配子、果实和种子。在这里，我们综述了目前对植物自噬的理解和最新进展，包括对自噬调控和信号传导以及自噬体膜生物发生的见解。此外，我们还描述了自噬如何促进植物发育、代谢、生物和非生物胁迫耐受性，以及自噬领域在作物改良应用研究方面的发展方向。
