Figure 6From: Seed-specific elevation of non-symbiotic hemoglobin AtHb1: beneficial effects and underlying molecular networks in Arabidopsis thalianaEffects of AtHb1 overexpression on energy metabolism of seeds. Plants were grown under control conditions and moderate hypoxia. (A) Levels of hydrogen peroxide (H2O2), (B) Adenylate energy charge (AEC) and (C) ATP levels. (D) Relative expression levels of genes involved in ATP synthesis quantified by qRT-PCR after hypoxic treatment. 1 - ATPase (At2g21870), 2 - ATPase (Chl) (At1g15700), 3 - NADH-DH (At5g47890), 4 - NADH:ubi (At5g18800), 5 - COX5C (At5g61310), 6 - COX5C (At3g62400), 7 - AOX1 (At1g32350). Mean values ± standard deviation are presented (n = 5); asterisks indicate statistical significant differences according to a student's t-test (p < 0.05, A-C).Back to article page
