Arabidopsis thaliana (L.) Heynh. (Brassicaceae)
General description:
Arabidopsis thaliana is a small herb in the mustard family, native to Europe, Asia and North Africa, and naturalized in many other parts of the world. It grows in disturbed habitats and may be considered to be a weed. It is a fast growing plant that completes its life cycle in four to six weeks. It typically grows from 5 to 25 centimeters tall. It grows with a large cluster of hairy leaves at the base of the plant, and a few leaves scattered along the stem. Small white flowers are clustered at the tip of the stem. Fruits are elongated pods that burst open when ripe, scattering 20-30 seeds.
History, uses and importance:
Arabidopsis thaliana is the most intensively studied species of plant in the world. Its small size and fast reproduction enables researchers to grow many plants quickly and for multiple generations of the plant. The plant is hardy and easy to propagate. In 1943, botanist Frederick Laibach suggested that these characteristics made the species well suited for use as a model organism to study plant genetics. Laibach and his students used radiation to produce mutated Arabidopsis in order to study the genetic basis of the mutations and the normal functions of the genes of unmutated plants. Many other researchers also began working with Arabidopsis in the latter half of the 20th century.

Its genome can be more intensively studied because it has very little DNA and there is no better known plant in the world. In the year 2000, it became the first plant to have its entire genome sequenced (all of its DNA described).
