    Notes: Nucleoside diphosphate (NDP) kinase has a central role in the synthesis of (deoxy-)trinucleotides. In addition, mutations in the gene encoding NDP kinase have been shown to have important consequences for Drosophila development and mammalian tumorogenesis. We have overexpressed, in Dictyostelium discoideum, a genomic clone encoding the enzyme NDP kinase. The concomitant increase in the levels of RNA and enzyme activity identifies a 5′ non-coding genomic region of 0.9 kb as being the complete promoter region. Overexpression of wild-type NDP kinase has no effect on development. This is also true for an inactive mutant H122C that does not have a dominant inhibitor effect. Overexpression of the P105G mutant NDP kinase, which is known to be affected in its stability in vitro, only leads to a small increase in total NDP-kinase activity. Thermal and chemical denaturation experiments demonstrate the formation of hexameric hybrids between wild-type and mutant monomers.

    Notes: Abstract 3,4,9,10-Perylenetetracarboxylic dianhydride (PTCDA) was deposited using organic molecular beam deposition (OMBD) onto various substrates, i.e. mica(0001), Au(111) layers on mica, and Se-passivated GaAs(100). Layer thicknesses were from 2 to 30 nm. Reflectance and transmittance measurements were performed in order to identify PTCDA absorption features and find suitable laser wavelengths for subsequent Raman investigations. Despite the low thicknesses the Raman spectra reveal strong scattering by the molecular vibrational modes, in particular above 1200 cm–1. Frequency shifts of various modes in the layers from their values in PTCDA source material may indicate the influence of the substrates. Similar shifts were also observed in infrared spectra of the same materials.

    Description / Table of Contents: Zusammenfassung Die Empfindlichkeit von Kartoffelknollen gegenüber der vonErwinia carotovora erzeugten bakteriellen Fäule stieg mit zunehmender Lagertemperatur stark an. Auch mit zunehmender Lagerdauer erhöhte sie sich, insbesondere bei höheren Temperaturen. Der Gehalt an Phenolen und die Trockensubstanz der Knollen verringerten sich mit steigender Temperatur. Im Gegensatz dazu war die Aktivität der Dehydrogenase-Enzyme der bei höheren Temperaturen lagernden Knollen erhöht. Keine Beziehungen wurden zwischen der Fäule-Empfindlichkeit der Kartoffeln und dem Gehalt an Zuckern festgestellt.
    Notes: Abstract Susceptibility of potato tubers to bacterial soft rot caused byErwinia carotovora was greatly increased when stored at relatively high temperature (30°C). Least rotting took place at low temperature (5°C). Increasing storage period lead to increase in tuber susceptibility to the disease, particularly at relatively high storage temperature. Ortho-dihydric phenols and dry matter contents of tubers were greatly decreased when they were stored at relatively high temperature as compared with those stored at low temperature. In contrast, activity of dehydrogenase enzyme was higher in tubers stored at relatively high temperature than of those of stored at low temperature. No correlation was found between susceptibility of tubers to rotting and the resulting physiological changes in their sugars contents due to temperatures and length of storage period.

    Description / Table of Contents: Zusammenfassung In den ägyptischen Distrikten Giza und Kena gesammelte Proben von Zuckerrohrpflanzen, die das Mosaikvirus (Sugarcane Mosaic Virus, SCMV) enthielten, ergaben den SCMV-Stamm D mit seinen Unterstämmen Da und Dc. Die Bestimmung erfolgte nach physikalischen Merkmalen und nach den am Wirt induzierten Symptomen. Die Stärke des Auftretens der 3 Pathogentypen war örtlich verschieden. Der Stamm D war stärker in Giza als in Kena, bei den Unterstämmen Da und Dc war es umgekehrt. Verdünnungsgrenzpunkt, thermaler Aktivitätsgrenzpunkt und Lebensdauerin vitro rangierten für die 3 Pathogentypen zwischen 10−3 bis 10−6, 50°C bis 63°C sowie bis zu 48h. Diese Merkmale variierten innerhalb jedes der 3 Stämme bzw. Unterstämme.
    Notes: Abstract Twentyfour samples of naturally mosaic infected sugarcane plants were collected from Giza and Kena Governorates of A. R. E. They were identified as SCMV strain D and its substrains Da and Dc according to their physical properties in diseased samples and symptoms produced on differential hosts. The two substrains are recorded for the time in Egypt as incitants of this disease. Distribution frequency of strains varied with locality. Strain D was distributed more in Giza Governorate than in Kena Governorate while frequency of substrains Dc and Da was of a reverse trend. Dilution end point, thermal inactivation point and longevityin vitro for strain D and its substrains Da and Dc ranged 10−3–10−6, 50°C–63°C, and up to 48 h respectively. These properties varied also within each strain.

    Description / Table of Contents: Zusammenfassung Die Wurzelexsudate von Weizen, Sorghum und Mais reduzierten das Wachstum der PilzeRhizoctonia solani (Tomaten-Umfallkrankheit) undFusarium oxysporum f. sp.cepae (Zwiebelwelke), förderten dagegen die Vermehrung des auf diese Pilze antagonistisch wirkendenBacillus subtilis. Die chemische Analyse zeigte erhebliche Unterschiede zwischen den Exsudaten der drei Pflanzenarten bezüglich Art und Menge von Zukkern und Aminosäuren. Das Wachstum der drei Mikroorganismen wurde in unterschiedlicher Weise durch Glukose sowie die Aminosäuren Phenylalanin, Serin und Glutaminsäure beeinflußt. Die Rolle der Wurzelexsudate bei der Ausbreitung der Tomaten-Umfallkrankheit und der Zwiebelwelke wird erörtert.
    Notes: Abstract Root exudates of wheat, sorghum and maize reduced growth ofRhizoctonia solani andFusarium oxysporum f. sp.cepae and increased growth ofBacillus subtilis in vitro. Analysis of these exudates showed that they were variable in their composition of sugars and amino acids. Growth of the tested microorganisms increased as the glucose content of the medium increased up to 3% for the bacterium and 4–5% for fungi. They also increased in growth as the concentration of certain amino acids increased. The role of such substances in favouring attacks of these fungi to tomato or onion plants is discussed.
