Ascorbate Peroxidase and Catalase Activities and Their Genetic Regulation in Plants Subjected to Drought and Salinity Stresses
The role of H2O2 in plants experiencing water deficit and salinity is highlighted and major outcomes of studies on CAT and APX activity and genetic regulation in drought- and salt-stressed plants are synthesized. Expand
The olive tree: a paradigm for drought tolerance in Mediterranean climates
An overview of the driving mech- anisms adopted by olive trees to face drought stress is provided with the aim of better understanding plant-soil interactions. Expand
Effects of different irradiance levels on some antioxidant enzymes and on malondialdehyde content during rewatering in olive tree
The activities of SOD, CAT, APX, POD and LOX, and MDA levels decreased during the rewatering period in both leaves and roots and these decrements were faster in plants rewatered in semi-shade conditions (SHP) than in plants under environmental light (NSHP). Expand
Metal content of southern Italy honey of different botanical origins and its correlation with polyphenol content and antioxidant activity
Summary Seventy-eight samples of southern Italy honey from five different floral origins (chestnut, eucalyptus, citrus, multifloral and sulla) were screened to quantify the polyphenol and metalExpand
Influence of water deficit and rewatering on the components of the ascorbate-glutathione cycle in four interspecific Prunus hybrids
The levels of total ascorbate, total glutathione and H 2 O 2 were directly related to the increase of drought stress and subsequently decreased during rewatering and could limit cellular damage caused by active oxygen species during periods of water deficit. Expand
Lipoxygenase activity and proline accumulation in leaves and roots of olive trees in response to drought stress.
The accumulation of PRO indicates a possible role of PRO in drought tolerance and increases of MDA content and LOX activity show that the water deficit is associated with lipid peroxidation mechanisms. Expand
Correlation between hormonal homeostasis and morphogenic responses in Arabidopsis thaliana seedlings growing in a Cd/Cu/Zn multi-pollution context.
Results show that the Cd/Cu/Zn-induced changes in root morphology are caused by a hormonal unbalance, mainly governed by the auxin/cytokinin ratio. Expand
Nutraceutical properties and polyphenolic profile of berry skin and wine of Vitis vinifera L. (cv. Aglianico).
The strong antioxidant ROS-scavenging activity, determined by both DPPH and FRAP assays, and the high resveratrol content confer high sensory characteristics resulted to be associated with positive nutraceutical properties of these grapes and wine. Expand
Osmotic regulation in leaves and roots of olive trees during a water deficit and rewatering.
Osmotic adjustment in olive trees was associated with active and passive osmotic regulation of drought tolerance, providing an important mechanism for avoiding water loss. Expand
Lipids and proteins—major targets of oxidative modifications in abiotic stressed plants
ROS is introduced and their relationship with abiotic stress-caused consequences in crop plants is highlighted, and the various physiological/biochemical aspects of oxidative damage to lipids and proteins in stressed crop plants are examined. Expand
