Effect of zeolite and irrigation treatments on grapevine leaves, an interdisciplinary approach
AimsGlobal warming depicts a real challenge for viticulture. As found by PubMed results, a 90% increase in the abiotic stress publications number...

Transcriptome analysis in abiotic stress conditions in higher plants
Drought, high salinity, and low temperature are major environmental factors that limit plant productivity. Plants respond and adapt to these stresses... -
Signal transduction in plant cold acclimation
Temperate plants respond to low temperature by activating a cold acclimation program leading to enhanced tolerance to freezing temperatures. This... -
Plant salt tolerance
Soil salinity adversely affects crop productivity and quality. The success of breeding programs aimed at salinity tolerant crop varieties is limited... -
Plant responses to heat stress
The heat stress response is characterized by inhibition of normal transcription and translation, higher expression of heat shock proteins (hsps) and... -
Sensors of abiotic stress in Synechocystis
Systematic mutagenesis of histidine kinases in combination with DNA microarray technology has allowed us to identify sensors for cold, hyperosmotic... -
Abscisic acid signalling
Signalling of abscisic acid (ABA) in plants is characterized by an amazing number of secondary messengers that are part of the pathway or modulate... -
Environmental Oxidative Stress – Environmental Sources of ROS
Environmental factors are known sources for oxidative stress. In consequence of the numerous influences that define our environment, environmental... -
Endogenous Oxidant-Generating Systems
Although organisms respiring air oxygen use their energy sources in an optimal way they are threatened by the compulsory formation of reactive oxygen... -
Low Molecular Weight Antioxidants
Low molecular weight antioxidants are an important part of the antioxidative defense mechanisms of cells and organisms. This chapter gives a short... -
Modulation of Cellular Signaling Processes by Reactive Oxygen Species
Exposure of cells to reactive oxygen species (ROS) may result not only in cell death by excessive oxidation of biomolecules but also cause the... -
Glutathione
Glutathione is the most abundant non-protein thiol in cells. It is a tripeptide with two important structural features: the thiol group and the... -
The Broad Spectrum of Responses to Oxidative Stress in Proliferating Cells
Proliferating mammalian cells exhibit a broad spectrum of responses to oxidative stress, depending on the stress level encountered. Very low levels... -
Pesticides in the Great Lakes
Pesticides have been widely and heavily used in agriculture in the Great Lakes Basin (approximately 93000 tons were used in 1995 alone). Herbicides... -
Somatic and Zygotic Embryogenesis in Avocado
Avocado is a species widely cultivated for its highly nutritious fruit. Currently, soil-borne diseases such as Phytophthora root rot are severe... -
Differential Gene Expression During Somatic Embryogenesis
Somatic embryogenesis is a complex developmental program in which somatic cells are induced for a commitment towards forming totipotent... -
Embryogenesis in Catharanthus roseus: Roles of Some External Factors in Proliferation, Maturation and Germination of Embryos
Catharanthus roseus is an important medicinal plant that contains two well-known anticancerous alkaloids, vincristine and vinblastine. Cell... -
Participation of Plant Hormones in Determination and Progression of Somatic Embryogenesis
In vitro culture protocols have been developed for many species, mainly using empirical approaches, to induce somatic embryogenesis from various... -
Brominated Flame Retardants in the Great Lakes
Brominated flame retardants in the Great Lakes have not been as well studied as many of the polychlorinated pollutants, especially PCBs, but in the...
