ABSTRACT
Arabidopsis (rockcress) is a genus in the family Brassicaceae. Representatives of Brassicaceae family are small-flowering plants, some of them are important crops such as cabbage, cauliflower, radish, and canola. Arabidopsis genus includes nine species and eight subspecies. The subspecies delimitation is quite recent, and is based on morphological and molecular phylogenetics (Elizabeth 2000). Arabidopsis thaliana
commonly known as thale cress, has 10 chromosomes in diploid stage and was the first plant to have its entire genome sequenced. Most of the species in Arabidopsis are indigenous to Europe and only two species are found in North America and Asia.
