Shoots detached from their roots and leaves detached from the stalk were compared with intact wheat (Triticum aestivum) plants. In leaves of detached shoots the nitrogen was mobilized rapidly, exopeptidase activities decreased, and endopeptidase activities remained stable or increased. If individual leaves were detached, the proteins were degraded more slowly, exopeptidases remained active longer, and endopeptidase activities were comparable to those observed in leaves of detached shoots. An accumulation of amino acids was observed in individually detached leaves but not in leaves of detached shoots. The presence of the roots and interactions within the shoot influenced the mobilization of proteins in a particular leaf. K
