Abstract:
Summary The recent progress in “omics” approaches, which allow the identification and quantification of hundreds to thousands of biological molecules in a single sample, has allowed their wide application in the plant sciences. Their use has permitted the detailed characterization of the developmental and environmental factors that control plant responses to abiotic stress and provided a basis upon which to base approaches to improve plant stress tolerance. This chapter reviews relevant aspects of the “omics” technologies themselves and highlights the main considerations in getting from a plant sample to analyzed data. As the majority of fundamental plant research uses Arabidopsis as a model plant, we restrict this chapter to review examples of how the application of “omics” approaches has allowed the characterization of abiotic stress responses and the use of these data to support early discovery research to engineer plants with improved stress tolerance.
