Abstract
Arabidopsis thaliana is the most popular plants in scientific fields whereas it is used as molecular genetics plant model because it can be manipulated easily and has a relatively small genome of approximately135 mega base pairs. This plant possessed many known mechanisms of DNA repair, producing an unusual pattern of inheritance. Because of the unique characteristics of the plant, A. thaliana has considered as a model plants for many studies. It is also extensively studied as a model for flower development. Importantly, the integral sequence of the Arabidopsis genome allowed the swift discovery of the molecular basis of recognizing mutant plant, which made it convenient and a powerful to recognize genes that are involved in many aspects of the plant life cycle. This review deals with the unique importance and characteristics that make A. thaliana a better choice for scientists and researchers interested in the study of living things, particularly those with interest in molecular plants.
