Which Organism Is Known As Drosophila Of Plant Kingdom

Arabidopsis thaliana is often referred to as the “Drosophila of the Plant Kingdom”. It is a small angiosperm, a dicot weed, and is highly valued for its small size, low number of chromosomes, fast growth, and ability to self-fertilize. For these reasons, it is widely used as a model organism for research in plant biology, genetics, and molecular biology.

Many mutant varieties have been identified.

#Arabidopsis thaliana Arabidopsis thaliana is a small plant, typically growing to a height of 20-25 cm, and belonging to the mustard family. It is notable for being the first plant whose whole genome was sequenced. Let’s learn more about its key facts!

Key Facts About Arabidopsis thaliana
