Relative Cytochrome c Content in Isolated Mitochondria from Florets of the Fertile and Sterile Sunflower Lines.

The relative amount of cytochrome c was determined by protein blot analysis and densitometry, working within a linear range of 20 to 40 μg of mitochondrial proteins as determined experimentally. The data are the average values of four independent experiments (±se), for each of which mitochondrial preparations were derived from four to eight sunflower heads. Statistical analysis was performed using Student's t test on sample means (** 0.001 < P ≤ 0.01).
