Seed Germination under High-Salinity Conditions.

Seeds of wild-type, azi1 mutant, or AZI1-overexpressing lines were germinated on standard medium in the absence or presence of 150mM NaCl. Tolerance was assessed 3 d later as percentage of germinated seeds (radicle protrusion). Average and standard deviation was calculated from three separate experiments performed with 40–50 seeds per line. Bottom panel: plate scan of one representative experiment (day 3, 150mM NaCl). Note that, although emerged radicles are seen in Col-O control and 35S::AZI1, the latter grows more vigorously.
