    Notes: Abstract One isoform of the branching enzyme (BE; EC 2.4.1.18) of potato (Solarium tuberosum L.) is known and catalyses the formation of α-1,6 bonds in a glucan chain, resulting in the branched starch component amylopectin. Constructs containing the antisense or sense-orientated distal 1.5-kb part of a cDNA for potato BE were used to transform the amylose-free (amf) mutant of potato, the starch of which stains red with iodine. The expression of the endogenous BE gene was inhibited either largely or fully as judged by the decrease or absence of the BE mRNA and protein. This resulted in a low percentage of starch granules with a small blue core and large red outer layer. There was no effect on the amylose content, degree of branching or λmax of the iodine-stained starch. However, when the physico-chemical properties of the different starch suspensions were assessed, differences were observed, which although small indicated that starch in the transformants was different from that of theamf mutant.

    Description / Table of Contents: Summary A nationwide planning of Analytical Chemistry in universities should meet two requirements: formulation of a common minimum programme for all universities and a well-balanced spread of research themes over the different universities. In the Netherlands this planning is the object of “ISOAN”, the Intersubfaculty Deliberation on Analytical Chemistry. Perhaps spectacular results have not yet been obtained, however thinking about these subjects has led to a more lucid picture and better mutual understanding.
    Notes: Zusammenfassung Eine solche allgemeine Planung für die Analytische Chemie sollte zwei Forderungen erfüllen: die Aufstellung eines gemeinsamen Mindestprogramms für alle Universitäten und eine ausgewogene Verteilung der Forschungsthemen auf die verschiedenen Hochschulen. In den Niederlanden gehört diese Planung zu den Aufgaben des »ISOAN« (Intersubfakultäts-Beratung über Analytische Chemie). Obwohl bisher keine besonders auffallenden Ergebnisse erzielt wurden, konnte doch durch die Beratungen ein klares Bild der Analytischen Chemie und ein besseres gegenseitiges Verständnis erreicht werden.
