Despite its small nuclear genome and minute chromosomes, the model plant Arabidopsis thaliana has become a well established model in the field of plant cytogenetics. Since 2000, most cytogenetic and epigenetic approaches have been developed for this species and its congeners. In this chapter, we describe two step-by-step protocols for preparing chromosome preparations from root tip meristems and generative organ tissues of A. thaliana. Although both protocols have been optimized for A. thaliana, the detailed procedures are equally applicable to other members of the genus Arabidopsis as well as other crucifer species (Brassicaceae).
