    Notes: Summary In the first inbred generation (I1) of cv. Black 4495 a dark green, slowly growing mutant (coded ds) was found, whereas the I1 of its self-compatible dihaploid, B16, comprised this ds mutant and in addition the mutants virescens (v) and yellow margin (ym). The occurrence of ds and ym might trace back to diploid S. phureja, one of the ancestors of Black 4495. No lethal mutants were observed in I1 of B16. Analysis of I1 of cv. Gineke revealed a simplex condition for virescence and either duplex or triplex heterozygosity for one lethal gene. On the other hand, the I1 of its dihaploid, G254, segregated for virescence and for three different lethal genes. It is shown that both in B16 and in G254 homozygosity of an S-bearing translocation causes early death of embryo and endosperm, thus preventing seed development. From this study it appeared that the three lethal genes from G254 affect germination rate of the seeds. The genotypes at 11 loci of B16 and G254 are presented.

    Genetics of self-compatibility in dihaploids of Solanum tuberosum L. 4. Linkage between an S-bearing translocation and a locus for virescens (1978)

    Notes: Summary Three dihaploids of Solanum tuberosum (two self-compatible, one self-incompatible) were found to be heterozygous for a monogenic recessive virescent mutant. Intercrossing resulted in the expected 3 : 1 ratio only in crosses involving one self-compatible and one self-incompatible parent. Self-compatible x self-compatible matings produced F1's in which 6:1 was found. The same ratio was observed in the self progeny of the two self-compatible dihaploids. This significant deviation could be explained by assuming linkage (25% crossing-over) between v and an S-bearing translocation. This translocation causes self-compatibility in the dihaploids used and early lethality when homozygous.

    Genetics of self-compatibility in dihaploids of Solanum tuberosum L. 5. The S-genotype of tetraploid potato cultivar gineke (1978)

    Notes: Summary Investigations of the genetics of self-compatibility and self-incompatibility in dihaploids and diploid derivatives from cv. Gineke revealed the presence of S 1, S2 and S 3 at the S-locus of Gineke and in addition an S 1-allele on a translocation. By means of a complete tester set involving the S-alleles S 1, S2 and S 3 (all from Gineke) and S 4 (from Black 4495) it was demonstrated that some Gineke dihaploids were compatible with all six testers. This indicated a fourth S-allele in Gineke, which differs from those in the tester series and was therefore assigned S 5. Additional evidence was obtained from an analysis of F1's from crosses of two S 5-bearing dihaploids and one of the testers. So the S-genotype of cv. Gineke was identified as S 1S2S3S5/S1, the second S 1 being the S-allele on a translocated fragment.

    Determination of the base-pairing content of four specific tRNAs by infrared spectroscopy (1977)
    New York : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: Infrared spectroscopy was used for the determination of the base-pairing content of four specific tRNAs in deuterium oxide solution. Infrared spectra were obtained in the 1750-1550 cm-1 region at various temperatures ranging from about 15 to 90°C. Melting curves were constructed by plotting the molar extinction coefficient at ν = 1657 cm-1 versus temperature. These transition curves enabled us to determine the ranges of temperature which correspond to the ordered (partially double-stranded) or randomly coiled structure of the tRNA. For a set of wavenumbers the extinction coefficients at these temperatures were used for the calculation of the base-pairing content. The procedure employed here is based on a method described earlier by Thomas [(1969) Biopolymers 7, 325-334]. For the conditions selected for this investigation (Mg2+-free D2O-buffer; 0.01M tris-DCl, 0.015M NaCl, pD 7.5) the results of this determination agree within the limits of errors with the number of base pairs predicted by the cloverleaf model.

    Notes: Die Ähnlichkeitstheorie hat den Weg gezeigt, die Gesetzmäßigkeiten des Wärmeüberganges mit Hilfe dimensionsloser Kennzahlen auszudrücken. Die Anzahl der zur eindeutigen Beschreibung eines Vorganges notwendigen Kenngrößen ist recht verschieden, sie ist z. B. besonders groß bei komplizierten Austauscherformen. Bei der Zusammenfassung der Einzelfaktoren zu Kennzahlen hat man gewisse Freiheiten, die man dazu benützen kann, die Gesetzmäßigkeiten bei der Berechnung von Wärmeaustauschern in einer möglichst zweckmäßigen Form darzustellen. An einem Beispiel wird gezeigt, daß die Rechnungen sich verhältnismäßig einfach durchführen lassen.

    Notes: Die konstruktiven Voraussetzungen für Laboratoriumszentrifugen mit bisher in der Praxis nicht erreichbaren Fliehkräften werden dargelegt. Das entwickelte Gerät, das im Gegensatz zu anderen Bauarten nur eine einzige radial um die Drehachse rotierende Zelle für die Einsatzflüssigkeit besitzt, wird beschrieben. Es ermöglicht bei 84 000 U/min Normalbeschleunigungen von 584 000 g, bei 120 000 U/min und kleineren Präparatmengen von 915 000 g. Besondere Einsätze zur Erfassung des Sediments bringen bei präparativen und möglicherweise auch analytischen Arbeiten besondere Vorteile.

    Free radicals in colloidal systems: Formation and decay of radicals in the tensides α-hexadecyl-ω-hydroxypoly(oxyethylene) and α-tetradecyl-ω-(sodium sulfonato)tri(oxyethylene) (1978)
    New York : Wiley-Blackwell

    Notes: Organic radicals were produced in the tensides C16H33(OCH2CH2)21OH and C14H29(OCH2CH2)3-SO3Na in aqueous solutions using a short pulse of high energy electrons. The radicals were formed by OH attack on the (OCH2CH2)x-parts of the tensides. The decay of the 250nm absorption of the radicals was recorded at different initial radical concentrations and tenside concentrations. Several radicals could be produced in one micelle. Radicals formed in the same micelle decay within microseconds or faster. The half life time τ1 in a micelle carrying two radicals is 2,0·10-6 s for C16H33(OCH2CH2)21 OH and less than 6·10-7 s for C14H29(OCH2CH2)3SO3Na. A model for intramicellar radical-radical reactions is proposed according to which the rate is faster in tensides of high critical micelle concentration. Single radicals in micelles of C16H33(OCH2CH2)21OH can deactivate each other without leaving the micelles. This intermicellar reaction is discussed in terms of the rate of diffusion-controlled micelle-micelle encounters, an encounter time of 7·10-8s, and the above time τ1 for intramicellar reaction. The observed rate constant 2k of intermicellar reaction is 3,5·106 mol-1·l·s-1. At low tenside concentrations, the bimolecular rate constant increases since more single tenside radicals are present in solution. They react rapidly (ca. 108 mol-1·l·s-1) with radicals in micelles. Single radicals in C14H33(OCH2CH2)3-SO3Na micelles cannot directly react with each other because of the Coulombic repulsion between two anionic micelles. Reaction occurs after the exit of a tenside radical from its micelle, the rate of which depends on the micellar equilibrium Mn⇄Mn-1+M (M: tenside molecule; n: agglomeration number of micelle). A single radical in solution reacts with a single radical in a micelle with 2k = 1,0·108 mol-1·l·s-1 and with another single radical in solution with 4,0·107 mol-1·l·s-1.γ-Irradiation of both tensides in aqueous solution leads to slight increases in viscosity, followed by turbidity beyond the “gel dose” and phase separation. These effects are explained in terms of crosslinking of tenside molecules. Formation of a large network requires bridges between all participating tenside molecules (not only bridges between micelles).

    Notes: Es wird die Spaltung der Mutterkornalkaloide vom Polypetid-Typus mit Hydrazin beschrieben. Neben kleineren Spaltstücken wird die vollständige Peptidseitenkette als dreigliedriges saures Spaltstück erhalten, wobei das bei der totalen Hydrolyse mit Säuren und Alkalien als Ketosäure auftretende Glied nun in reduzierter Form erhalten wird. Aus Dihydro-ergotamin isolierte man Propionyl-L-phenyl-alanyl-L-prolin und aus den anderen Alkaloiden die entsprechend aufgebauten Peptidsäuren, deren Konstitution durch Synthese bewiesen werden konnte.
