<em>Arabidopsis</em> Auxin Mutant

Caption

This image shows two thale cress plants (Arabidopsis thaliana), common weeds that are distant cousins of mustard and other cruciferous vegetables. The one on the left is wild-type, capable of responding normally to signals provided by the hormone auxin. The plant on the right is a mutant, lacking a key gene that can respond to auxin messages, resulting in severely stunted growth.
