In page Arabidopsis thaliana:

"

Botanists and biologists began to research A. thaliana in the early 1900s, and the first systematic description of mutants was done around 1945.[1] A. thaliana is now widely used for studying plant sciences, including genetics, evolution, population genetics, and plant development.[2][3][4] Although A. thaliana the plant has little direct significance for agriculture, A. thaliana the model organism has revolutionized our understanding of the genetic, cellular, and molecular biology of flowering plants.[citation needed]
