The planned European legal form Societas Privata Europaea (SPE) is a limited liability company of a closed group of shareholders, and thus is comparable to the German GmbH. At the European-level, the SPE serves as a supplement to the European Limited Liability Company (SE), which proved to be too difficult for small and medium-sized companies for various reasons. The SPE will be introduced on the basis of a European regulation, the content of which has been largely agreed to by the member states.

Environmental stresses represent the most limiting factors for agricultural productivity. Apart from biotic stress caused by plant pathogens, there are a number of abiotic stresses such as extremes in temperature, drought, salinity, heavy metals and radiation which all have detrimental effects on plant growth and yield. However, certain plant species and ecotypes have developed various mechanisms to adapt to such stress conditions. Recent advances in the understanding of these abiotic stress responses provided the impetus for compiling up-to-date reviews discussing all relevant topics in abiotic stress signaling of plants in a single volume. Topical reviews were prepared by selected experts and contain an introduction, discussion of the state of the art and important future tasks of the particular fields.

Mitogen-activated protein kinase (MAPK) pathways are modules involved in the transduction of extracellular signals to intracellular targets in all eukaryotes. Distinct MAPK pathways are regulated by different extracellular stimuli and are implicated in a wide variety of biological processes. In plants, there is evidence for MAPKs playing a role in the signaling of abiotic stresses, pathogens, plant hormones, and cell cycle cues. The large number and divergence of plant MAPKs indicates that this ancient mechanism of bioinformatics is extensively used in plants and may provide new molecular hands on old questions.

Florens Sauerbruch untersucht, welche Funktionen das Beschlussmangelrecht im Kontrollgefuge der Aktiengesellschaft erfullt. Er analysiert die Anreizstrukturen, die missbrauchliche Klagen begunstigen und erlautert die Wirkungsweise des Freigabeverfahrens und gibt Auslegungsempfehlungen fur die Tatbestandsmerkmale des Paragraphen und entwickelt Vorschlage zur weiteren Reform des Aktiengesetzes."
