Thellungiella

Thellungiella is a genus of plants in the family Brassicaceae closely related to "Arabidopsis", but in the subclade Eutremeae. In recent classifications, the genus is no longer recognized, and the formerly included species are now placed in the genus "Eutrema" or "Schrenkiella."
They are commonly known as saltwater cresses because of their ability to grow in salty environments. As well as salinity, "Thellungiella" has an exceptionally high resistance to cold, drought, and oxidative stresses. As a result, it has become an extremophile model for abiotic stress tolerance studies and two "Thellungiella" genomes have been sequenced. See the list of sequenced plant genomes. "Thellungiella" is an excellent model organism for several other reasons: it has a relatively small genome size (approximately twice that of A. thaliana), a rapid life cycle, small size, high seed production, and ecotypes available that show a range of stress responses.
The genus includes the following species:
