Arabidopsis Relatives Major Species

Isatis tinctoria (woad)

Isatis tinctoria, aka Isatis indigotica, has long been used as a source of the blue dye, indigo, and numerous phytopharmacological agents. As such, it has received a different kind of attention at the transcriptomic level than other species, broadening our perspective on the study of eXtremophytes.

Arabidopsis lyrata

The eXtreme plant bona fides of Arabidopsis lyrata stem from its preference for sandy, gravelly, rocky or chasmophytic “soil”. At the molecular level, its value has been greatest for its contribution to understanding of mechanisms of mutation, selection and genome-size transformations in plants.

Schrenkiella parvula

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.

Eutrema salsugineum

E. salsugineum (formerly Thellungiella salsuginea) was originally selected as a model organism because of its ability, in the natural world, to function in saline, cold, and freezing conditions, and for its efficient mobilization of resources in poor or degraded soils.

Arabidopsis halleri

Arabidopsis halleri is a close relative of the model plant Arabidopsis thaliana, differing in at least two important ways.  First, unlike A. thaliana, A. haleri is […]
