Die fluoreszierenden Stoffe aus den Malpighischen-Gefäßen der Wildform und verschiedener Augenfarbenmutanten von Drosophila melanogaster

Abstract

The Malpighian tubules of Drosophila melanogaster accumulate a great number of substances, many of which fluoresce. This paper is concerned with the identification of these substances by chromatography and their location by fluorescentmicroscopy (fig. 4, 5). It appears that they mainly belong to the following three groups: Pteridines, tryptophane and some of its metabolites, and riboflavine (tab. 1). The pattern of fluorescent substances of the eye color mutants cn, v, se, st, bw, ry, and w vary significantly. The patterns of these mutants are compared and discussed with that of the wild-type.
