Abstract

During the last decade, microarrays became a routine tool for the analysis of transcripts in the model plant Arabidopsis thaliana and the crop plant species rice, poplar or barley. The overwhelming amount of data generated by gene expression studies is a valuable resource for every scientist. Here, we summarize the most important findings about the abiotic stress responses in plants. Interestingly, conserved patterns of gene expression responses have been found that are common between different abiotic stresses or that are conserved between different plant species. However, the individual histories of each plant affect the inter-comparability between experiments already before the onset of the actual stress treatment. This review outlines multiple aspects of microarray technology and highlights some of the benefits, limitations and also pitfalls of the technique. This article is part of a Special Issue entitled: Plant gene regulation in response to abiotic stress.

► Common or non-overlapping transcriptional responses during abiotic stresses in plants. ► The plant core environmental stress response contains systemic responses and priming. ► Comparability of expression data and common standards of information (e.g. MIAME). ► Sampling, data processing and systematic errors in designing microarray experiments. ► We discuss evolutionary implications and discuss implications for genetic engineering.
