Deciphering the mechanisms of thermo-adaptation of an extremophilic desert plant

Global warming is changing the habitability of many places for many species on Earth. Understanding thermo-adaptation in plants is critical and timely for global sustainability, food security and species conservation. In the 1970s, Carnegie scientists studying Tidestromia oblongifolia in Death Valley discovered that this Amaranth is highly adapted to high temperatures. Almost 50 years have passed and the molecular basis of its remarkable thermo-adaptation of photosynthesis remains largely uninvestigated.

The summer intern will be involved to decipher the mechanisms of thermo-adaptation of T. oblongifolia at multiple scales. Specifically, he/she will examine if the trichomes play a substantial role in the mechanisms of thermo-adaptation of T. oblongifolia and compare root architecture of T. oblongifolia with a heat sensitive Amaranth. Plants and material will be ready for the student at the beginning of internship.
