Oxidative stress and some antioxidant systems in acid rain-treated bean plants Protective role of exogenous polyamines
It was found that AR significantly increased peroxidase and decreased catalase activities at the first hours after treatment, and both enzyme activities were enhanced that could contribute to the scavenging and detoxification of active oxygen species. Expand
Generation and scavenging of reactive oxygen species in chloroplasts : a submolecular approach
The specific traits of oxygen chemistry are examined as a basis of the step-wise electron acceptance by O 2 , giving rise to incompletely reduced highly reactive oxygen species (ROS) comprising bothExpand
The finding that PRs, considered before as plant-specific proteins, are also expressed in other organisms, suggests that these proteins share an evolutionary origin and possess activity essential to the functioning and survival of living organisms. Expand
The importance of non-photosynthetic pigments and cinnamic acid derivatives in photoprotection
Excess light and UV-radiation are hazardous natural stress factors, and plants have evolved a range of avoidance and tolerance strategies employing versatile tools against these constraints. TheExpand
Stress Protective Role of Secondary Metabolites Diversity of Functions and Mechanisms
Secondary metabolites play a major role in the adaptation of plants to the changing environment and in overcoming stress constraints. This flows from the large complexity of chemical types andExpand
Phenylamides in plants
Recent data pointing to the structural similarity of plant phenylamides with those found in insect toxins suggests their role as a common defense tool in various organisms. Expand
Endogenous isoprene protects Phragmites australis leaves against singlet oxygen
The possible protective role of endogenous isoprene against oxidative stress caused by singlet oxygen ( 1 O 2 ) was studied in the isoprene-emitting plant Phragmites australis. Leaves emittingExpand
Drought Tolerance in Cotton: Involvement of Non‐enzymatic ROS‐Scavenging Compounds
Compounds with reactive oxygen species (ROS)-scavenging ability were studied. High-performance liquid chromatography (HPLC) pattern of polyphenols, contents of proline and carotenoids, andExpand
Effect of water deficit and potassium fertilization on photosynthetic activity in cotton plants
Application of the JIP test by using chlorophyll fluorescence data revealed that the drought sensitive Nazilli 84-S was more responsive to potassium fertilization than Sahin 2000, as judged by a number of parameters representing quantum efficiency of the processes and energy fluxes in photosystem (PS) II.
