Beschreibung:
<jats:p>The distribution of lectin in various tissues of <jats:italic>Phaseolus vulgaris</jats:italic> L. (var. red) has been investigated with the use of a sensitive solid phase enzyme immunoassay. Plants were divided into roots, stems and leaves with a further dissection of the stem into internodes. Isolated tissues, from plants 3‐10 weeks old, were screened for their lectin content, and the development of the lectin over this period determined. Stems and roots contained significant amounts of lectin, whereas the leaves only exhibited very low levels. Furthermore, a pronounced and differential increase in the biosynthesis of the lectin was observed in stem sections between 6 and 10 weeks, where the third internode displayed the highest lectin level.</jats:p>
