Analysis of the expression of AOX proteins during the development of soybean cotyledons. A, Immunoblot of AOX proteins in cotyledon mitochondria. Each lane contains 20 μg of mitochondrial protein. Numbers across the top refer to seedling age in days postimbibition. 5‘, Longer exposure of 5 min; 14′ and 20′, shorter exposures of 14 and 20 min, respectively. Results from one of two independent experiments are shown. B, Intensity of the bands on the immunoblot exposure shown in the central panel of A. Values are expressed as the percentages of the sum of the d-10 band intensities.
