Polychlorinated Naphthalenes in the Great Lakes
This review examines the sources and occurrence of polychlorinated naphthalenes (PCNs) in the Great Lakes environment and summarizes current...
-
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...
-
Somatic Embryogenesis in Chestnut
Somatic embryogenesis is an important biotechnological tool that demonstrates significant benefits when applied to forest tree species; clonal...
-
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 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...
-
Perfluorinated Compounds in the Great Lakes
Perfluoroalkyl acids (PFAs) are released to the environment via their manufacturing processes, their use in commercial products, or indirectly via...
-
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....
-
Somatic Embryogenesis in Cryptomeria japonica D. Don: Gene for Phytosulfokine (PSK) Precursor
Genetic transformation requires a reproducible system for the regeneration of plants via somatic embryogenesis or organogenesis. We established...

Lipid Metabolism, Compartmentalization and Signalling in the Regulation of Pollen Tube Growth
To understand the biological context of lipid metabolism and signalling in pollen, we have to consider male gametophytes as organisms optimised...
-
The Actin Cytoskeleton in Pollen Tubes; Actin and Actin Binding Proteins
Actin cytoskeleton is well known to be a key element for the germination and the elongation of pollen tubes. It has been appreciated that the...
-
Toxaphene in the Great Lakes
Toxaphene is a major persistent organic contaminant in air, water and fish in the Great Lakes. The story of toxaphene in the Great Lakes, like that...
-
Polychlorinated Dibenzo-p-dioxins and Dibenzofurans in the Great Lakes
The history of “dioxin”, PCDD/F, contamination in the Great Lakes is reviewed. Occurrence, geographical distribution, and temporal trends in air,...
-
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...
-
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...
-
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...

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...

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...
-
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...
-
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...
