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...

Critical Phenomena in a Small World
We consider the behavior of various systems on a small-world network near a critical point. Our starting point is a different, nonrandom system with...

Who Is the Best Connected Scientist?A Study of Scientific Coauthorship Networks
Using data from computer databases of scientific papers in physics, biomedical research, and computer science, we have constructed networks of...
-
Scholarly Information Network
I review the background and some recent trends of a particular scholarly information network, ar**v.org, and discuss some of its implications for new...
-
Information Theory of Complex Networks: On Evolution and Architectural Constraints
Complex networks are characterized by highly heterogeneous distributions of links, often pervading the presence of key properties such as robustness...
-
The Small World Phenomenonin Hybrid Power Law Graphs
The small world phenomenon, that consistently occurs in numerous existing networks, refers to two similar but different properties — small average...
-
Extremal Properties of Random Structures
The extremal characteristics of random structures, including trees, graphs, and networks, are discussed. A statistical physics approach is employed...
-
Spectral Analysis of Random Networks
We review a general approach that describes the spectra of eigenvalues for random graphs with a local tree-like structure. The exact equations to the...
-
Course 1: Nonequilibrium Phase Transitions
Nonequilibrium phase transitions are discussed with emphasis on general features such as the role of detailed balance violation in generating...
-
Course 2: Mechanical Aging and Non-linear Rheology of Concentrated Colloidal Suspensions: Experimental Facts and Simple Models
Many colloidal systems display very non-Newtonian and solid-like behaviour when concentrated, a striking feature being the apparition of a yield...
-
Course 6: Glasses, Replicas and All That
In these lectures I will review the approach to glasses based on the replica formalism. Many of the physical ideas are very similar to those of older...
-
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...
-
Course 14: Hiking through Glassy Phases: Physics beyond Aging
Experiments performed on a wide range of glassy materials display many interesting phenomena, such as aging behavior. In recent years, a large body...

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...
