ROS production increases when plants are exposed to different kinds of stresses. The chief toxic effect of O2 and H2O2 resides in their ability to initiate cascade reactions that result in the production of the hydroxyl radical and other destructive species such as lipid peroxides. These dangerous ...
Production of a family of reactive oxygen species (ROS) is a common phenomenon. When plants are subjected to environmental stress, the balance between the production of ROS and the quenching activity of antioxidants is upset, often resulting in an oxidative damage. Plants with high levels of ...
Plants must cope with a variety of environmental stresses.Most types of abiotic stresses,such as drought,salinity,flooding,heat and cold stress,disrupt the metabolic balance of cells,resulting in the enhanced production of reactive oxygen species(ROS).While being well-known as a toxic by-product,...
Thus, coordination of ROS production and their activities between compartments is emerging as an important theme in our understanding of how growth and developmental programs are integrated. 展开 关键词:Meristem Plant Stems Plant Roots Reactive Oxygen Species NADPH Oxidase Plants Models, Biological Plant...
Leguminous plants have exclusive ability to form symbiotic relationship with soil bacteria of the genus Rhizobium. Symbiosis is a complex process that involves multiple molecular signaling activities, such as calcium fluxes, production of reactive oxygen species (ROS) and synthesis of nodulation genes. ...
时,就会不可避免的产 生R()S,在植物体内主要包括以下几种类型:超 氧根阴离子(O),氢氧根离子(OH’),羟基自南 基(一OH),过氧化氢(H:O)等... 植物细胞中产生RoS的部位有细胞膜,叶绿 体,线粒体和过氧化物体等(见图1),其中叶绿体 和线粒体是产生ROS的主要部位.ROS在线粒 体和叶绿体的产生途径主要是...
recent findings have confirmed that ROS/RNS biosynthesis/signaling are essential for advancing important cellular and metabolic processes in plants. Studies have suggested that the growth-promoting functions of ROS/RNS are mainly attributed to the differences in their production and subsequent scavenging, ...
In plants, reactive oxygen species (ROS) are short-lived molecules produced through various cellular mechanisms in response to biotic and abiotic stimuli. ROS function as second messengers for hormone signaling, development, oxygen deprivation, programmed cell death, and plant–pathogen interactions. Rece...
