Molecular analysis of plant homeostasis

干旱、盐碱、冰冻、高温、缺氧、强光、营养失衡等一系列异常环境参数统称为非生物胁迫。非生物应激导致脱水或渗透应激通过减少水的可用性至关重要的细胞功能和维持膨胀压力。植物在形态、解剖、细胞和分子水平上进化出了应对各种非生物胁迫的机制。一些对耐受性或适应性的反应是高度物种特异性的，而另一些则是相当普遍的，甚至在属于不同科和目的植物、微生物和动物中也是如此。在脱水或渗透胁迫的反应中，一系列相容的渗透渗透物被积累，用于渗透调节、水潴留和自由基清除。人们试图了解对某些非生物胁迫的耐受性的分子基础。我们对高等植物体内平衡的分子机制进行了广泛的研究，以了解植物耐胁迫的基础。这种研究的结果以出版物和其他方式提出

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
