Molecular analysis of plant homeostasis

非生物胁迫是指干旱、盐碱、冰冻、高温、缺氧、强光和营养失衡等异常环境参数的总称，非生物胁迫通过减少细胞重要功能所需的水分和维持膨压而导致脱水或渗透胁迫。植物在形态、解剖、细胞和分子水平上对各种非生物胁迫都有相应的反应机制，其中一些反应具有高度的种特异性，而另一些反应甚至在不同科、不同目的植物、微生物和动物中也是相当普遍的。响应于脱水或渗透胁迫，积累一系列相容的渗透调节剂，用于渗透调节、保水和清除自由基。人们试图了解某些非生物胁迫耐受性的分子基础。为了了解植物抗逆性的基础，我们对植物体内稳态的分子机制进行了广泛的研究。这种研究的结果以出版物和其他方式介绍

A number of abnormal environment parameters such as drought, salinity, freezing, high temperature, anoxia, high light intensity and nutrient imbalances etc. are collectively termed as abiotic stresses.Abiotic stresses lead to dehydration or osmotic stress through reduced availability of water for vital cellular functions and maintenance of turgor pressure. Plants have evolved mechanisms to respond to various abiotic stresses at morphological, anatomical, cellular and molecular levels.Some responses to tolerance or adjustment are highly species specific whereas others are fairly common even among plants belonging to different families and orders, microorganisms and animals. In response to dehydration or osmotic stress a series of compatible osmolytes are accumulated for osmotic adjustment, water retention and free radical scavenging. Attempts have been made to understand the molecular basis of tolerance to certain abiotic stresses. We have carried out extensive studies on the molecular mechanism related to the homeostasis in higher plants to understand the basis of stress tolerance. The outcome of such research was presented in the form of publications and other means
