All this is associated with some pathology in human beings as cancer, cardiovascular diseases, Alzheimer, Parkinson, sclerosis, among others. This percentage increases when plants are subjected to stress conditions such as salinity, drought, cold stress or high temperatures. Phenolic compounds are one of the main secondary metabolites of plants and its presence in animal kingdom is due to the ingestion of them.
In the non-transformed controls, the inoculated areas with P.

Por lo anterior, las auxinas en el tallo pueden influir en el crecimiento de las yemas, a una determinada distancia Bennett et al. Both in our organism and in plants, when the generation of ROS overcomes antioxidant defence mechanism, an oxidative stress occurs at cell level which can lead to cell death. These results suggest that maintaining polyamine biosynthesis through the enhanced SAMDC activity in grapevine leaf tissues under gibereoinas stress conditions could contribute to the enhanced ROS scavenging activity and a protection of photosynthetic apparatus from oxidative damages.
Therefore, the function of ROS in metabolism is dual; they are toxic for cells when they accumulate in excess, but at low levels it has been proved that they can function as bio-signalling molecules.

Even a decrease in DHA in relation to control plants occurred, and accordingly, an increase in the redox state of ascorbate Table 1. The role of mitochondrion in plant response to biotic funcionss. OH could be formed by the reaction of O2.
Systemic cell death is elicited by the interaction of a single gene in Nicotiana and gene VI from cauliflower mosaic funcions. Mutual interaction of auxin and cytokinins in regulating correlative dominance. Suppression of tobacco mosaic virus-induced hypersensitive-type necrotization in tobacco at high temperature is associated with downregulation of NADPH oxidase and superoxide and stimulation of dehydroascorbate reductase.

Under optimal growth conditions, ROS are mainly produced at a low level, being their rate of production drastically increased when plants are exposed to environmental stresses. Gibberellin-enhanced indoleacetic acid biosynthesis: This effect resulted in fubciones strong decrease in the redox state of ascorbate in NaCl-treated plants Table 1.
Nowadays, we know that damages produced in plants under stress fiberelinas are mediated, partly, by an increased production of ROS at subcellular level. They also establish a link to the adaptation of immune system through white blood cells recruitment. Distinct isoprenoid origins of cis- and trans-zeatin biosyntheses in Arabidopsis.
The observed resistance of transgenic lines to bacterial wild fire seemed to be independent of tissue necrosis, as observed in other plant-pathogens interactions Kiraly et al. Furthermore, this group of enzymes is supported by other enzymes which act regenerating antioxidant molecules employed by enzymes that remove H 2 O 2.
In these compartments the O2. The Plant Cell Among the GA 3 applications, the 10 mg L -1 one showed the best results in both clones.
En Phaseolus vulgaris Castro et al. Foods rich in vitamin C are citric, red and green paprika, and fruits and vegetables in general.
Salt stress produced an alteration in the fluorescence chlorophyll parameters in grapevine leaves. Journal of Experimental Botany 59, Furthermore, the H2O2 is produced by the action of peroxidases in the apoplast, and it is formed as a reaction product by the action of other enzymes in different compartments glicolate oxidase and xanthine oxidase in peroxisomes, acyl-CoA oxidase in glyoxysomes, amine oxidase and oxalate oxidase in apoplast.
