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... -
12 Baker’s Yeast: a rising foundation for eukaryotic sphingolipid-mediated cell signaling
Saccharomyces cerevisiae has been an invaluable tool for the dissection of sphingolipid metabolic pathways and cloning of enzymes involved in... -
1 Phospholipid synthesis in mammalian cells
Phospholipids are the main components of biological membranes and as such act as the major permeability barrier between cells and the extracellular... -
2 Phospholipid synthesis and dynamics in plant cells
Phospholipids represent the second family of lipids after the galactolipids in photosynthetic tissues and the first in non-photosynthetic tissues.... -
Modeling Calcium Waves
We present an introduction to the mathematics of calcium waves, both intracellular and intercellular. After a discussion of the earlier models I... -
Regulation of IP 3 Receptors by IP 3 and Ca 2+
Inositol 1,4,5-trisphosphate ( IP 3) receptors are intracellular Ca 2+ channels that mediate release of Ca 2+ from intracellular stores. The channels... -
Hormone-Mediated Intercellular Calcium Signalling in an Insect Salivary Gland – Pathways and Mechanisms
The salivary glands of the blowfly Calliphora vicina are a favourable preparation for investigations into spatio-temporal Ca 2+ dynamics in an intact... -
From Simple to Complex Ca 2+ Oscillations: Regulatory Mechanisms and Theoretical Models
Intracellular Ca 2+ oscillations most often appear as regular spikes. However, complex Ca 2+ oscillations in the form of bursting or chaos have also... -
11 Plant sphingolipids
Plants contain a multiplicity of sphingolipid metabolites, such as long-chain bases, long-chain base phosphates, ceramides, glycosylceramides,... -
5 Sterol metabolism and functions in higher plants
Higher plants synthesize a bewildering array of sterols, with sitosterol, stigmasterol, and 24-methylcholesterol as major compounds. All plant... -
6 Sterol biochemistry and regulation in the yeast Saccharomyces cerevisiae
Saccharomyces cerevisiae has been a major model system for the study of sterol biosynthesis and function. All of the genes encoding the enzymes... -
7 Mammalian ACAT and DGAT2 gene families
Mammalian isozymes of ACAT, DGAT, and MGAT are encoded by the ACAT and DGAT2 gene families. These enzymes catalyze the synthesis of neutral lipid... -
Aging and mitochondrial dysfunction in the filamentous fungus Podospora anserina
In the filamentous fungus Podospora anserina, mitochondria play a paramount role in life span control and aging. During aging, these organelles... -
The human Werner Syndrome as a model system for aging
The aging process is one of the most challenging biological pathways to understand. Applications of model systems for aging have contributed... -
Aging and the programmed death phenomena
Biochemical mechanisms of the programmed death phenomena are considered at levels of unicellular organisms, mitochondria, cells, groups of cells, and...
