Name

Thellungiella O.E. Schulz
Synonym of Eutrema

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[1] or Schrenkiella.[2]

They are commonly known as saltwater cresses[3] 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:

Thellungiella botschantzevii
Thellungiella parvula
Thellungiella pumila
Thellungiella runcinata
Thellungiella salsuginea
Thellungiella toxophylla
