Systems Biology: necessary developments and trends
At the end of this definition of Systems Biology through exampling, we discuss ambitions, goals, and challenges relating to this new discipline. We...

Control of Cell Proliferation and Growth by Myc Proteins
Myc proteins act as signal transducers that alter cell proliferation in dependence on signals from the extracellular environment. In normal cells,...
-
Regulation of the heat shock response by heat shock transcription factors
The heat shock response is characterized by a rapid and robust increase in heat shock proteins upon exposure to protein-damaging stresses. This...
-
Template-induced protein misfolding underlying prion diseases
Proteins with prion properties are closely associated to a class of fatal neurodegenerative illnesses in mammals and to the emergence and propagation...

Storage Proteins and Peroxidase Activity During Zygotic and Somatic Embryogenesis of Firs (Abies sp.)
Somatic embryogenesis was initiated from immature embryos of Abies concolor (Gord. et Glend), A. numidica De Lann. and A. cilicica Carr., A....

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...

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...
-
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...

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....
-
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...
-
Plant salt tolerance
Soil salinity adversely affects crop productivity and quality. The success of breeding programs aimed at salinity tolerant crop varieties is limited...
