Thellungiella parvula
Schrenkiella parvula
Eutrema parvulum, also called Thellungiella parvula, is one of several extremophile relatives of Arabidopsis, is notable for its tolerance to high salinity, freezing temperatures, water deficit and resource-poor environments. Under saline conditions, for example, its LD50 in NaCl is 600 mM for mature plants; below that, while Na  gradually accumulates, K  levels are maintained. With a small nuclear genome of ~140Mb in 7 chromosomes (N), Eutrema parvulum represents an extremophile model species.
