    Notes: [Auszug] Anthers of the diploid lily (variety Enchantment Orange) were fixed with glutaraldehyde followed by OsO4, essentially as described by Ledbetter and Porter4. Thin sections were cut on a Porter Blum microtome, stained with uranyl acetate and lead citrate and viewed with a Siemens Elmiskop I at 80 kV. ...

    Notes: [Auszug] A close scrutiny of the conventional molecular structure of saccharides used in this study and their effect on pigment production by P. rubrum (Table 1) suggests that the configuration of the saccharide molecules themselves is significant and that only those hexoses and pentoses having a core of ...

    Notes: [Auszug] The materials used were disks of potato tuber 5 mm in diameter and the epidermal cells of the lower surface of the leaves of Rhoeo discolor9 which are rich in anthocyanin and thus easy to observe under the high-power lens of a light microscope. These tissues have been used successfully by several ...

    Notes: [Auszug] IN a previous communication1 I reported the discovery of a sucking stylet in ticks which, to all appearances, was the homologue of the hypopharynx in other blood-sucking arthropods. On the analogy of the feeding mechanism in ticks, it seemed reasonable to postulate that in biting ...

    Intergeneric transformation betweenRhizobium andAzotobacter (1969)

    Antonie van Leeuwenhoek 35 (1969), S. 533-540 
    Details
    ISSN: 1572-9699
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Attempts were made to transform two strains ofAzotobacter, viz.A. chroococcum andA. vinelandii with the DNA ofRhizobium leguminosarum, R. japonicum, R. meliloti andR. trifoli. Resistance to streptomycin or crystal violet was used as marker for screening purposes. The frequency of transformation varied between 0.05 to 0.95 percent. The transformants also acquired a few other characters of the donor strains.

    Notes: [Auszug] WITH reference to Dr. B. Jobling's letter1, I wish to point out that, as already mentioned2, the hypothesis advanced by me concerning the feeding mechanism in blood-sucking diptera was of a tentative character, and that the object of my communication was not to ...

    Phase relations in three charnockites from Pallavaram-Tambaram (1970)

    Contributions to mineralogy and petrology 27 (1970), S. 239-243

    Topics: Geosciences
    Notes: Abstract Chemical data on eight ferromagnesian silicates from a syenitic and two tonalitic charnockites from the type area near Madras show remarkably regular cation fractionation patterns. The distribution coefficients for magnesium-iron point to equilibration under granulite facies metamorphism. Orthopyroxene-garnet-biotite subsystem has been found to be of a near invariant nature, while the compositions of orthopyroxene and biotite in the nongarnetiferous tonalite are different. Analysis of phase equilibrium by Thompson type AFM projection strongly indicates that pressure, temperature and the chemical potential of water were constant for assemblages separated by large distances.
