Fig. 7From: The Arabidopsis paralogs, PUB46 and PUB48, encoding U-box E3 ubiquitin ligases, are essential for plant response to drought stressEffects of oxidative, salt and osmotic stresses on seedling germination. Surface sterilized cold treated seeds of the indicated plant lines were plated on agar media containing 0.5 x MS, 0.5% sucrose (control) supplemented with: a methyl viologen (MV) at 0 (yellow bars), 0.5 μM (orange bars) or 1 μM (brown bars); b NaCl at 0 (light green) or 150 mM (green) NaCl; c mannitol at 0 (light blue) or 300 mM (blue); d ABA at 0 (light purple) or 1 μM (purple). Green seedlings were scored 5 (a-c) or 6 (d) days later. Data shown are average ± SE. Statistically significant changes from WT plants (P < 0.05) are marked with asterisksBack to article page
