Book Description. In an attempt to improve communication between disciplines in this field, we have aimed to cover what we perceive to be all relevant aspects of photooxidative stress: from primary reactions to molecular genetics and the devising of strategies for engineering stress tolerance in plants.

[Christine H Foyer] -- In an attempt to improve communication between disciplines in this field, we have aimed to cover what we perceive to be all relevant aspects of photooxidative stress.

Book: Causes of photooxidative stress and amelioration of defense systems in plants. + pp. Abstract: The subject is covered in an interdisciplinary manner, with contributing authors encouraged to provide personal perspectives on their topics whilst discussing them in depth.

The light‐dependent generation of active oxygen species is termed photooxidative stress. This can occur in two ways: (1) the donation of energy or electrons directly to oxygen as a result of photosynthetic activity; (2) exposure of tissues to ultraviolet irradiation.

The light‐dependent destruction of catalase compounds the problem. Photoinhibition and photooxidation only usually occur when plants are exposed to stress.

Active oxygen species are part of the alarm-signalling processes in plants. These serve to modify metabolism. While other photosensitizers like humic acids also contribute to photooxidative stress, (bacterio-) chlorophyll a is regarded as the main cause of 1 O 2 -generation in photosynthetic bacteria.

Independently of light, processes like lipid peroxide decomposition or hypochloric acid reacting with hydrogen peroxide can generate 1 O 2 [ 1 ].

Such oxidative stress has been shown to occur in plants exposed to high and low temperatures, particularly in combination with high light intensities, drought, exposure to air pollutants (e.g.

ozone or sulphur dioxide), ultraviolet light, and herbicides such as paraquat [1 ]. The chapter focuses on abiotic stress–induced ROS production, oxidative damage caused by ROS, and the role of the antioxidative defense system in plants growing under different abiotic stresses.

(eds.), Causes of photooxidative stress and amelioration of defense systems in plants. Plants depend on physiological mechanisms to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezing, salt, UV, intense light, heavy metals and SO2.

Many of these cause excess production of active oxygen species in plant cells. Plants have evolved complex defense systems against such oxidative stress. ” In causes of photooxidative stress and amelioration of defense systems in plants.

In the course of dehydration, the gas exchange and chlorophyll (Chl) fluorescence were measured under irradiance of μmol m −2 s −1 in detached apple leaves, and the production of active oxygen species (AOS), hydrogen peroxide (H 2 O 2), superoxide (O 2 −), hydroxyl radical (−OH), and singlet oxygen (1 O 2), were net photosynthetic rate (P N) was limited.

Photoinhibition and photooxidation can occur when plants are exposed to stress. High light in synergy with other stress factors such as chilling, drought, or low carbon dioxide supply reduces the capacity of photosynthetic systems to utilize incident radiation, leading to a.

Plants have defense mechanisms against oxidative damage that are activated during stress to regulate toxic levels of ROS. Antioxidant and nonantioxidant systems are involved in ROS detoxification.

During the last decades, antioxidant enzymes have been used to develop transgenic plants that have increased tolerance to several stresses. Asada, K. Production and action of active oxygen in photosynthetic tissues.

To investigate the antioxidant defense system, chilling stress-induced changes of antioxidant enzymes were examined in the leaves of cucumber (Cucumis sati6us L.). Chilling stress preferentially enhanced the activities of the superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione reductase (GR) and peroxidase specific to guaiacol, whereas it induced the decrease of catalase activity.

Maintenance of a high antioxidant capacity to scavenge the toxic ROS has been linked to increased tolerance of plants to these environmental stresses [ 22, 23 ]. Water stress is one of the most important environmental factors inducing physiological changes in plants, such as decreasing water potential of the cells and the stomatal closure, resulting in reduced CO2 availability for the plants and inhibiting photosynthesis.

One common feature of these stress conditions is the development of oxidative processes mediated by reactive oxygen species (ROS). The effects of lead (Pb) stress on plant growth, lipidperoxidation and on the activity of antioxidant enzymes were studied in Sansevieria roxburghiana Schult.
