abstract：:Using the aphid stylet technique (14)C ATP was shown to be readily taken up into the sieve elements of willow. At the same time this compound was found to be metabolised during uptake resulting in labelled ADP and AMP appearing in the stylet exudate. Longitudinal movement of labelled ATP was also found to occur.Measur...
