Arabidopsis Growing in a Field - Wow, it is a Real Plant!

Glenn Nice, Weed Diagnostician, Department of Botany & Plant Pathology, Purdue University

In the world of genetics this little inconspicuous winter annual mustard is about as famous as any Hollywood actor. It has and still is being used as a model specimen for much of the plant genetics work done by industry and academia. Arabidopsis appears to be so willing to give up its DNA that even I can get a good gel from DNA extracts.

Arabidopsis is not a big player in the world of weeds when compared to chickweed, ragweeds, and the many other weeds out there. It has very little impact on farming practices and appears to be easily controlled with fall or spring burndowns.
