Schrenkiella parvula – a 7 chromosome member of the Brassicaceae – has an eXtreme ability, in the natural world, to function in the hypersaline conditions surrounding Lake Tuz in central Anatolia, Turkey.  It is also notable for its tolerance of high levels of other cations, especially Li+ and Mg2+ and of Boron. These extreme adaptations were central to the initial decision to sequence the genome of this species.
