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.
