AbstractArabidopsis is universally acknowledged as the model for dicotyledonous crop plants. Furthermore, some of the information gleaned from this small plant can be used to aid work on monocotyledonous crops. Here we provide an overview of the current state of knowledge and resources for the study of this important model plant, with comments on future prospects in the field from Professor Pamela Green and Dr Sean May.
