    Due to their sessile lifestyle, plants are exposed to a variety of stresses and have to develop ingenious mechanisms to avoid or cope with the consequences of extreme stress factors. Plant genomes have therefore evolved to meet environmental challenges and many plant genes are dedi- cated to stress protective mechanisms.
    Examples of adverse environmental factors include drought, salinity, solar radiation (excess light or high light intensities, UV-light), extreme temperatures (heat and low temperature/freezing stress), and pollutants (heavy metals, herbicides). In addition, low concentrations of essential macro- and micronutrients or conditions that result in poor uptake of these nutrients are also perceived as stress by plants. For example, phosphate deficiency is one of the most common reasons for poor plant growth and reduced crop yield [1]. Sometimes, two and even more abiotic and/ or biotic stress factors impose their effects simultaneously, so that plants have to deal with a multitude of challenges [2]. Oxidative stress is a common consequence of many of these factors.
