Contents of soluble polyamines in the leaves of all investigated Thellungiella and nine Arabidopsis accessions. Leaves were harvested either before (NA) or after (ACC) cold acclimation. Note the different scales of the ordinates in the different panels. The accessions are ordered from the lowest LT50 after cold acclimation on the left to the highest on the right separately for Thellungiella and Arabidopsis. The bars represent means ± SE from measurements of eight to 10 samples from two independent experiments for Thellungiella and three samples from one experiment for Arabidopsis.
