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...

The Material-Independent Signatures of Life.Forensic Tools of Astrobiology
Biological life is intimately related to the geochemical conditions on Earth and is fit for this planet’s energy flux. It has often been suggested...
-
The Early History of Bioenergy
Energy is most commonly defined as the potential to do work. The maintenance of the living state requires a constant flow of energy through the...

Assembling the Early Puzzle of Life
So far no theory, no approach, no set of formulas, and no blackboard scheme have been found satisfactory in explaining the origin of life. The...

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....

The Early History of Bio-Information
In a general sense, the information level of a structure equals the minimum number of instructions needed to specify the structure (Orgel 1973). The...

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...
