Fig. 1From: Root iTRAQ protein profile analysis of two Citrus species differing in aluminum-tolerance in response to long-term aluminum-toxicityEffects of Al-toxicity on plant growth and root Al concentration in C. sinensis and C. grandis seedlings. a-c Whole plant, shoot and root dry weights (DWs). d Root Al concentration. Bar represents the mean ± SE (n = 10 for plant DW or 4 for Al concentration). Differences among four treatment combinations were analyzed by 2 (species) × 2 (Al levels) ANOVA. Different letters above the bars indicate a significant difference at P < 0.05Back to article page
