Arabidopsis thaliana is known as Drosophila of the Plant kingdom. It is a small angiosperm, a dicot weed. Due to its small size, less number of chromosomes, faster growth and self-fertilization, it is used as a model organism for research in plant biology, genetics and molecular biology.
Many mutant varieties have also been identified.
It is the first plant, whose whole genome was sequenced. It is small in size around 20-25 cm tall. It belongs to the mustard family. Let’s know more about Arabidopsis thaliana key facts.
