Arabidopsis research refers to the study of the small flowering plant Arabidopsis thaliana, which is widely used as a model organism in plant biology research. Arabidopsis has a relatively simple genome, short life cycle, and small size, making it ideal for studying plant biology, genetics, physiology, and development. Researchers use Arabidopsis to investigate a wide range of topics, including gene function, stress responses, hormone signaling, and plant-environment interactions. This research has contributed significantly to our understanding of plant biology and has implications for crop improvement, genetic engineering, and environmental sustainability.
