Illumination of etiolated bean seedlings causes a fast change in the ATP-content of the stem hook. This change is mediated through the phytochrome system. We present evidence that breakdown as well as synthesis pathways of the ATP-turnover cycle can be affected. Both in vivo and in vitro illuminations are effective. This proves that even in a cell-free system a functional relationship exists between the photoreceptor and enzymes involved in ATP-metabolism.
