Abstract

Oxidative stress occurs in plant due to various environmental stressors like drought, high temperature, pathogen invasion, heavy metals, pesticides etc. when plant faces these conditions, reactive oxygen species (ROS) are produced in the chloroplast, mitochondria, plasma membrane, peroxisomes, ER and cell wall due to the leakage of electrons. Depending upon its concentration the role of ROS is decided if less then it will act as a signaling molecule but if in excess it will damage the cellular machinery of plants as the production of species like free radicals would take place. Though to combat these stress plants have antioxidant defense machinery which include enzymatic and non- enzymatic which lower down the level of ROS. Through genetic engineering more tolerant plants are produced which include modification of key genes like transcription factors. In this review article the molecular physiology of plants is discussed where in the factors contributing to stress including biotic and abiotic factors and various mitigation strategies.
作物毒性介导的氧化应激及其缓解策略
由于干旱、高温、病原体入侵、重金属、农药等多种环境胁迫,植物会发生氧化应激,当植物面临这些条件时,叶绿体、线粒体、质膜、过氧化物酶体、内质网和细胞壁由于电子的泄漏而产生活性氧(ROS)。ROS的作用取决于它的浓度如果它的浓度较低,那么它就会作为一种信号分子,但是如果浓度过高,它就会破坏植物的细胞机制,因为会产生自由基等物质。为了对抗这些胁迫,植物具有抗氧化防御机制,包括酶和非酶,可以降低活性氧水平。通过基因工程,包括转录因子等关键基因的修饰,可以生产出更具耐受性的植物。本文综述了植物分子生理学的研究进展,包括生物胁迫和非生物胁迫,以及各种缓解胁迫的策略。
