Current projects:

• Local adaptation along an altitudinal gradient in Arabidopsis arenosa

Using reciprocal transplant and common garden experiments, we investigate the genetic basis (RNA-seq) and underlying molecular mechanisms (metabolomics) of adaptive traits involved in local adaptation along an altitudinal gradient in Arabidopsis arenosa.

• Altitudinal variation in freezing resistance in polyploid and diploid populations of Arabidopsis arenosa

In this project, we study the ability of plants to cope with frost stress along an altitudinal gradient and address the following questions: (1) Do we observe differences in freezing resistance between low- and high-altitude populations collected in different mountains (Alps and Carpathian Mountains) and (2) Do we observe differences in freezing resistance between diploid and polyploid populations of Arabidopsis arenosa.
