On the localization of genes on certain autosomes of man through chromosome aberrations

Summary Chromosome aberrations permit the assignment to and the exclusion of genes on certain chromosomes or definite segments. Only exclusion methods are discussed. All relevant data are compiled in a table from which it can be determined, which genetic systems are excluded from certain autosomal segments.

---

Zusammenfassung Angeborene Chromosomenaberrationen ermöglichen die Zuordnung und den Ausschluß von Genen auf dem betroffenen Segment. Nur die für Lokalisierungsausschlüsse verwendbaren Methoden werden diskutiert. Aus einer Zusammenstellung der bisherigen Befunde wird ermittelt, welche genetischen Systeme von einer Lokalisierung auf bestimmten Autosomen(segmenten) des Menschen ausgeschlossen werden können.

Blockade des Gibberellinsäure-Transports in Hypocotylsegmenten durch Trijodbenzoesäure. Zugleich ein Neuer Agarblocktest auf Gibberelline

Summary Gibberellic acid (GA) was incubated in agar blocks, transported through hypocotyl sections of sunflower plants, and collected in acceptor blocks of plain agar. The amount of GA transported through the sections was tested with dwarf pea plants using a new test method in which the acceptor block was applied directly to the test plant. The GA transport was significantly lower through hypocotyl section from plants which had been treated with triiodobenzoic acid (TIBA) before isolation of the sections. TIBA inhibits the transport of GA.

La variabilité cytologique dans la descendance des femelles de Luffia ferchaultella steph. (Lepidoptera psychidae)

Summary The procedure which leads to the restoration of the diploid chromosomal number in the egg of the parthenogenetic Luffia ferchaultella is similar in all the eggs laid by one female. But it may vary in the eggs of closely related females (mother and daughters or sisters). Therefore it is not a characteristic of the parthenogenetic strain.

Die Wirkung von Luftströmung auf die Antennen und das Flugverhalten der blauen Schmeissfliege (Calliphora Erythrocephala)

Summary Blowflies (Calliphora erythrocephala) are studied in the state of tethered flight.Subjected to air current from a windtunnel they move their antennae active against the direction of air current and decrease the amplitude of their wing beat gradually. Both the reactions are mediated by receptor organs in the joint between pedicel and funicle. Most likely one of the receptor organs is the organ of Johnston, which seems to be most responsive to vibrations and controls the wing beat, while the other organ is one single sensillum campaniforme, responsive both to angular deflection and vibration. This latter organ mediates the active positioning of the antennae according to air speed. The properties of the whole system in respect to control of flight are investigated and discussed.Finally, an analysis is given of the aerodynamic and elastic properties of the mechanical system which transfers air current to act as stimulus on the mechanoreceptors in the antennae.

Effect of different wave lengths of light on the behaviour of an Eriophyid bud mite, Aceria sheldoni

The effect of daylight passing through Cellophane filters on the behaviour of the eriophyid mite, Aceria sheldoni Acarina: Eriophyidae, was examined.The sensitivity of this mite to different wave lengths of light was demonstrated. The most attractive colours of Cellophane filters, beneath which the mites settled for feeding and reproduction, were the red and yellow, in contrast to the blue and green ones.

Zusammenfassung Die Wirkung von Tageslicht nach Durchgang durch Cellophan-Filter auf das Verhalten der Eriophide Aceria sheldoni (Ewing), Acarina: Eriophidae, wurde untersucht, Dabei ließ sich die Empfindlichkeit dieser Milbe gegenüber Licht verschiedener Wellenlängen nachweisen. Die anziehendsten Cellophan-Filter-Farben, unter denen die Milben zu Nahrungsaufnahme und Fortpflanzung schritten, waren Rot und Gelb, im Gegensatz zu blauen und grünen Filtern.

Elektronenmikroskopische Untersuchungen zur Genese des Golgi-Apparates (Dictyosomen) und ihrer Kernabhängigkeit beiAcetabularia

Summary The genesis of dictyosomes has been studied on nucleate and enucleateAcetabularia cells.Dictyosomes differentiatede novo from prestages, the perinuclear bodies, which are synthesized under the actions of nuclear ribonucleoprotein. Consequently the formation of dictyosomes is nucleus (DNA) dependent.This was shown by experiments using actinomycin and puromycin and by experiments on darkened and enucleate cells.There is a relationship between dictyosome structure and function and the morphogenetic activities of a cell.

Aspergillus Gracilis Bainier var. Sartoryi (Biourge) Batista,Lima e Vital n. var. — Sua importáncia filogenética

Summary We deal with a new variety ofAspergillus which we callAspergillus gracilis Bainiervar. sartoryi (Biourge) Batista, Lima and Vital.This variety appears to be very important under the phylogenetic point of view, apparently being an intermediate form betweenAspergillus andPenicillium.Its morphology resemblesA. gracilis but the conidia characteristics are distinct; we took the epithetsartoryi fromA. sartoryi Biourge which was not described by the respective author.We suggest, too, the transfer of the seriesA. restrictus, where we put our new variety, from the groupA. glaucus, to become independant, as a connective series in the phylogenetic development betweenAspergillus andPenicillium, since the type of the series and the other elements that it embraces does not produce sclerotia or cleistothecia and the conidial apparatus offers curious similarity toPenicillium. Besides, some fungi of the series grow well in certain culture media, in complete discordance with the members of the groupA. glaucus.

Induction of chromosomal breakage in cultured human leucocytes by luteoskyrin

Summary Luteoskyrin, a Polyhydroxy-Bis-Dihydroanthrachinon isolated from Penicillium islandicum Sopp, is known to have strong cytotoxic effects. In long-term cultures of Ehrilich-Ascites-Tumour cells it causes the formation of very long abnormal chromosomes (Schachtschabel). Experiments with short-term cultures of human leucocytes are reported on which have shown Luteoskyrin to induce chromosomal breaks and interchromosomal bridges.

Zusammenfassung Das Polyhydroxy-Bis-Dihydroanthrachinon Luteoskyrin, ein Stoffwechselprodukt des Schimmelpilzes Penicillium islandicum Sopp, hat eine starke cytotoxische Wirkung. In Langzeitkulturen von Ehrlich-Ascites-Tumorzellen verursacht es die Bildung von abnormal langen Chromosomen (Schachtschabel). Es wird über Versuche mit Kurzzeitkulturen von menschlichen Leukocyten berichtet, in denen durch Luteoskyrin Chromosomenbrüche und interchromosomale Brücken entstehen.

Beitrag zur Populationsgenetik der Pyruvatkinase menschlicher Erythrocyten

Summary In 214 healthy young Germans the activity of Pyruvatekinase from red blood cells has been determined. Three persons had values in the heterozygote range between 10.0 and 20.0 U. Suggesting a 2-allele-model the frequency of the three phenotypes in the German population can be calculated as followed: PK(A)=98.6%, PK(AB)=1.4%, PK(B)=0.005%.No correlation could be found between the distribution of blood-and serum-groups and the enzyme-activity.
