Abstract

The small cruciferous weed Arabidopsis thaliana, or thalecress, is the focus of an intensive, international plant genome research programme. Those characteristics of also make this small weed attractive for the teaching of Arabidopsis which are appropriate for genetics research genetics and plant biology. In this paper, experiments in basic Mendelian genetics are described, using two easily scored traits, namely leaf colour and the presence/absence of leaf hairs. Procedures for performing genetic crosses with Arabidopsis are described, including the use of male sterile mutants in simplifying genetic crosses for the beginner. Areas for teaching and research projects with Arabidopsis in broader aspects of plant biology are also discussed.
