逆境胁迫下植物线粒体生理响应研究法在乌龙茶加工中的应用分析

Application analysis for the methods of plant mitochondrial physiological response under adversity stress in Oolong tea processing

乌龙茶加工中叶片的生理生化变化一直是业界的研究热点之一,线粒体是细胞中重要的细胞器,也是最受关注的细胞器之一,随着近年研究发现线粒体还有调控细胞凋亡、参与细胞信号转导、生产活性氧等功能,也正成为线粒体研究领域内的新热点之一。本文对近年来其他植物线粒体在逆境胁迫下生理响应的研究进行综述,发现此研究领域是乌龙茶加工研究中的一个值得探讨的新方向,提出了对脂质过氧化和保护酶的研究从全叶向叶片线粒体深入、叶片显微结构观察向叶细胞线粒体超微结构观察深入、对乌龙茶加工中叶片是否发生细胞凋亡现象,开展乌龙茶加工中叶片线粒体研究,以期将乌龙茶加工过程的研究深入到细胞器水平,对丰富乌龙茶加工过程中的生理生化与品质形成关系具有深入研究的价值。

The research of physiological and biochemical changes in leaves is one of the industry's focal points in Oolong tea processing. Mitochondria is an important organelle in a cell, and is one of the hot spots in all organelles. As recent studies found, the regulation of apoptosis, involved in cellular signal transduction, production of reactive oxygen species(ROS) and other functions became the new hot spot in the field of mitochondrial research. In this paper, plant mitochondrial physiological response under adversity stress were reviewed. These will be a new direction to discuss in processing of Oolong tea. Lipid peroxidation and protective enzymes of entire leaves further to leaves mitochondria, microstructure of leaves further to ultrastructure of leaves mitochondria, whether apoptosis of leaves will occur or not in Oolong tea processing, all these researches ought to do in organelle level and exist a significant value for further research between the physiological and biochemical and formation of quality in Oolong tea processing.
