Stress measurements in F.distichus

The file contains two tables with (1) photosynthetic performance (PI_abs and Fv/Fm) and (2) gene expression (3 hsp genes) of F. distichus individuals from two populations (Svalbard and Kirkenes) during thermal stress experiments. Experiments were performed at 20˚C, 24˚C and 28˚C with measurements taken at 0 min (control), 15 min of stress, 60 min of stress and 24 hours of recovery.
