The germ-line limited chromosomes (Ks) [K being derived from 'Keimbahn' (Bauer, 1970)] of Acricotopus lucidus were studied in gonial and differential mitosis. After C-banding the soma chromosomes (Ss) are stained only at their centromeric regions whereas the Ks exhibit centromeric, intercalary and terminal heterochromatin. By X-raying sperms it was attempted to transfer K sections on or into Ss in order to bring finally S-linked K sections to polytenization in the salivary glands, and to obtain more knowledge about the structure of Ks. Seven Fl-larvae were detected with K-S-rearrangements: four with insertions of heterochromatic segments, two with insertions of sections with S-homologous banding pattern and one with a translocated K chromosome part, which consists of S-homologous euchromatic sections as well as of an intercalary and a terminal heterochromatic segment. The present results strongly suggest that the Ks of A. lucidus are derived from the Ss by rearrangements and by formation and accumulation of repetitive sequences.

“…Panitz (1972) in a review of Balbiani Ring activities in the Chironomid Acricopotus lucidus, points out two cases of position effect in connection with inversions: in Br-1 reported by Wobus et al, reported by Mechelke. Any possible effect of geographical origin must be dismissed.…”

The puffing patterns in polytene E chromosomes of Drosophila subobscura were followed in third-instar larvae and throughout the prepupa period. Two gene arrangements, Est and E1+2+9+12 were studied. A majority of puffs exhibit a similar pattern, but the puffs 61AC and 67AB behave differently in the two chromosomal arrangements, both in homozygotes and in heterozygotes. These two puffs are located at the end of the E12 inversion. This position effect is an interesting phenomenon that probably is not due to a heterochromatinization effect.

“…He showed that in cells of one of the three functionally different lobes of the salivary glands of the midge Acricotopus lucidus the disappearance of two Balbiani rings coincidod with the accumulation of pig ments within the secretion of the glands. Panitz (1972) has described the further correlation of these puffs to The most extensive study of this type has involved the :;ocrGtory proteins synthesized in the salivary glands of Ghironomus pallidivittatus. Grossbach (1969) was able to isolate the secretory proteins from C. pallidivittatus and Ç. tentans and subject them to electrophoresis on polyacrylamide gels.…”
