Multi-Parametric Screening in Arabidopsis thaliana Seedlings

Phenotypic screening and subsequent target identification approaches are very valuable to identify chemical probes that can be used to explore the connection between phenotypes and biological pathways. However, assessing a phenotypic effect in plants in a high-throughput fashion is a challenging task and often requires expensive readout devices. In this chapter, we describe a cost-effective multi-parametric screening procedure that is compatible with liquid-handling systems and that enables the assessment of phenotypes in Arabidopsis thaliana seedlings in an automated way.
