Light-mediated Oxygen Uptake Measured in Wheat Etioplasts.

An in vitro O(2) assay was used to measure early response of wheat (Triticum aestivum L.) etioplasts to light. A transient photoinducible O(2) uptake occurred when dark-grown etioplasts were initially exposed to light. The rate of inducible O(2) consumption was dependent on both the intensity of light and the quantity of organelle protein present. Higher… CONTINUE READING
