- Arabidopsis thaliana, a small mustard family plant, was first described by German botanist Johannes Thal in the 16th century.
- Friedrich Laibach in the early 1900s discovered Arabidopsis has only five chromosome pairs, making it genetically simple and suitable for research.
- Laibach advocated for Arabidopsis as a genetic model due to its ease of cultivation, self-fertilization, and small genome, but it initially received lukewarm reception.
- György Rédei in the 1950s recognized Arabidopsis's potential, creating mutant lines like Landsberg erecta and Columbia (Col-0), which became key reference strains.
- Arabidopsis research gained momentum in the 1980s with the development of transgenic plants and Agrobacterium-mediated gene transfer techniques.
- The complete genome of Arabidopsis was sequenced in 2000, solidifying its role as a premier model organism in plant biology.
- Arabidopsis is used to study various biological processes, including flowering, hormone signaling, and plant-pathogen interactions, with applications in crop improvement.
- The plant's resilience and ease of genetic manipulation have made it a central reference species in molecular genetics and environmental research.
