| 摘 要： | 种子的衰老是一个复杂的从量变到质变的生物学过程。种子衰老与线粒体功能异常密切相关,衰老的线粒体学说认为,线粒体中活性氧的过量产生是种子衰老的主要原因。深入了解种子衰老过程中线粒体的变化对于揭示种子衰老机理和种子安全保存具有重要意义。本文主要介绍了当前有关种子衰老过程中线粒体结构、呼吸作用和抗氧化系统的研究现状,并对种子衰老与线粒体关系研究中存在的问题进行了讨论。

| Abstract: | Seed aging is a complex biological progress from quantitative change to qualitative change.Seed aging is closely related to the dysfunction of mitochondria.In the view of the "mitochondria aging theory",the excessive accumulation of ROS in mitochondria is the main reason of seed aging.Understanding the changes takes place in mitochondria during seed aging is important to reveal the mechanism of seed aging and ensure safe conservation of seeds.In this paper,the current process of mitochondrial structure,respiration and antioxidant systems during seed aging were reviewed.Moreover,problems in the study of seed aging and mitochondria were discussed. |
