Molecular responses of higher plants to dehydration
A massive amount of data has been accumulating on the molecular responses of plants to water deficit. In plants, dehydration activates a protective...

Heavy metal signalling in plants: linking cellular and organismic responses
Heavy metals are required in plants as essential micronutrients or act as toxic compounds. How do plants perceive heavy metals and which signalling...

Introduction
Everywhere in the world, environmental stresses represent the most limiting factors for agricultural productivity. Besides plant-specific endogenous...

SlTDC modulates photosynthesis of senescent leaves in tomato
Melatonin (MT) is a key regulator in plants’ response to leaf senescence induced by aging or various abiotic stresses. Here, we demonstrated that...

Molecular genetics of genotoxic stress signalling in plants
Cells are under constant threat by endogenous and exogenous factors affecting DNA integrity. In response, complex signalling networks are activated...
-
Oxidative stress signalling
Oxidative stress arises from an imbalance in the generation and removal of reactive oxygen species (ROS) within cells. ROS are produced during...

Molecular Dissection of the Clathrin-Endocytosis Machinery in Plants
In the last few years, the endocytic vesicular uptake in plant cells has gained increasing significance in several physiological processes....
-
Dynamin-Related Proteins in Plant Endocytosis
Over the past decade, it has become evident that multiple endocytic pathways operate in eukaryotic cells, and several of these are dependent on...

In Vitro Culture of Arabidopsis Embryos
Arabidopsis thaliana is currently the most important model organism for basic molecular plant research. It is also a favourable model for...

Mode of Action of Plant Hormones and Plant Growth Regulators During Induction of Somatic Embryogenesis: Molecular Aspects
Plant hormones play critical roles in the establishment of somatic embryogenesis. During this process, somatic plant cells reverse their state of...

Somatic Embryogenesis in Pinus nigra Arn.: Some Physiological, Structural and Molecular Aspects
In this chapter we summarize different aspects of Pinus nigra somatic embryogenesis including initiation, maintenance and maturation on both solid...

The Microtubular Cytoskeleton in Pollen Tubes: Structure and Role in Organelle Trafficking
Microtubules are a fundamental component of plant cells, in which they achieve many critical functions. In pollen tubes, however, their specific...
-
Small GTPases and Spatiotemporal Regulation of Pollen Tube Growth
During in vivo growth, pollen tubes make a long journey toward the ovule, responding to long- and short-distance guidance cues and elongating...
-
The Pollen Tube: A Model System for Cell and Molecular Biology Studies
Pollen tubes, the active male gametophytes of seed plants, are the vectors carrying the male sperm cells to the egg cell of the female gametophyte...

Genome-Wide Expression Analysis of Genes Involved in Somatic Embryogenesis
Genome-wide expression analysis is an important tool for identifying and analysing genes involved in various biological processes, including cell...
-
Receptor-Mediated Endocytosis in Plants
Binding of ligands activates cell-surface receptors and triggers a series of signalling events. The activation of the receptors accelerates their...
-
Endocytosis and Endosymbiosis
Symbioses are widespread in nature and occur between organisms that belong to a large variety of taxonomic divisions (Hentschel et al. 2000). Most...

Endocytic Uptake of Nutrients, Cell Wall Molecules and Fluidized Cell Wall Portions into Heterotrophic Plant Cells
After arrival at the surface of heterotrophic cells, nutrients are taken up by these cells via endocytosis to sustain metabolic processes. Recent...

The Architecture and Properties of the Pollen Tube Cell Wall
The pollen tube wall differs in both structure and function from walls of vegetative plant cells. Cellulose represents only a small portion of the...

Somatic Embryogenesis in Chestnut
Somatic embryogenesis is an important biotechnological tool that demonstrates significant benefits when applied to forest tree species; clonal...
