Abstract
Membrane lipids change drastically in plants when they suffered from hypoxia (oxygen deficiency) stress. Overall, hypoxia stress lowers the contents of total lipids, inhabits lipid biosynthesis, and stimulates lipid degradation, leading to the accumulation of free fatty acids. Lipid alterations include changes in the contents of lipid classes, the extent of saturation, and the length of acyl chains. But the detail and systematic studies about lipid changes, as well as the function mechanism in hypoxia stress are poorly understood. Here, the major unanswered questions and suggestions on the study of the function of lipid in hypoxia stress were provided.
摘要
当植物遭受缺氧（氧气缺乏）胁迫时，其膜脂会发生剧烈变化。总的来说，缺氧胁迫会降低总脂含量，抑制脂类生物合成，刺激脂类降解，导致游离脂肪酸的积累。脂类的变化包括脂类含量的变化、饱和度的程度以及酰基链的长度。但是，关于脂类变化以及在缺氧胁迫中的功能机制的详细和系统的研究还知之甚少。本文就脂类在缺氧胁迫中的功能研究提出了主要的未解决问题和建议。
