    Pollen irradiation and the transfer of maternal genes in Pisum sativum (1984)
    Springer
    Theoretical and applied genetics 67 (1984), S. 245-248 
    Details
    ISSN: 1432-2242
    Keywords: Pollen ; Irradiation ; Gene transfer ; Pisum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Pollen of Pisum sativum was exposed to doses of 900 to 6,000 r of X-rays prior to pollinating a multiply marked genotype. The first generation progeny closely resembled that produced with unirradiated pollen. In the second generation, five loci were monitored, and the results showed that irradiation enhanced the proportion of maternal information transmitted to the progeny; the practical implications of the data, as well as the mechanism underlying the effect are discussed.

    The initiation of legumin synthesis in immature embryos of Pisum sativum L. grown in vivo and in vitro (1980)
    Springer
    Planta 149 (1980), S. 454-460 
    Details
    ISSN: 1432-2048
    Keywords: Embryo culture ; Enzyme-linked immunosorbent assay (ELISA) ; Legumin ; Pisum ; Protein (storage) ; Storage protein
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A highly sensitive immunoassay has been used for the detection of a major storage protein, legumin, in embryos of Pisum sativum L.; with this technique nanogram quantities could be measured. In the two varieties tested, legumin could be detected in embryos in vivo, when they had attained a fresh weight of 2·10-3 g and 3·10-3 g, respectively. Contrary to earlier claims, embryos cultured in vitro were shown to be capable of initiating legumin synthesis. This capacity to initiate legumin synthesis was confirmed by two-dimensional isoelectric focusing-electrophoresis and fluorography; embryos harvested before initiation of legumin synthesis and cultured in radioactive medium were shown to have synthesized legumin subunits. The amounts of legumin and total protein synthesized per unit fresh weight were consistently greater in vitro than in equivalent embryos grown in vivo.

    The cytology of cotyledon cells and the induction of giant polytene chromosomes inPisum sativum (1979)
    Springer
    Protoplasma 101 (1979), S. 73-80

    ISSN: 1615-6102
    Keywords: Cotyledon culture ; Pisum ; Polytene chromosomes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The cotyledon cells ofPisum sativum have high DNA contents. By appropriate culture techniques, some of these cells can be triggered into division. Two types of dividing nuclei were seen. Firstly those that were polyploid with metaphases containing chromosome numbers ranging in value from 4 x to 32 x. Included among these were unexpected numbers equivalent to 12 x and 14 x. Secondly there were cells containing giant polytene chromosomes and these progressed from prophase to a metaphase where the polytene chromosomes separated into constituent single chromosomes.

    Organization and mapping of legumin genes in Pisum (1986)
    Springer
    Molecular genetics and genomics 202 (1986), S. 280-285 
    Details
    ISSN: 1617-4623
    Keywords: Legumin genes ; Genetic loci ; Pisum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The organization of three classes of legumin gene has been studied by exploiting restriction fragment length polymorphisms. Hybridization of cDNA probes, representing different sub-families of legumin gene, to DNA from F2 and F6 plants from selected crosses showed that there was a tight linkage of individual genes within each of two sub-families. One of these sub-families has been mapped to a locus on chromosome 7 close to r, while the other maps to a locus near a on chromosome 1. The results from one of the crosses analyzed indicated that a third class of legumin gene is also linked to a.

    Notes: Summary We describe four genomic clones of pea 7S storage protein gene, one of which corresponds to convicilin, and the others to vicilin. Hybridization studies exploiting these clones, and previously identified cDNA clones, have enabled us to define six different loci. Three of these loci have been mapped to positions on chromosome 7.

    The photo- and electroinitiated polymerization of N-vinyl phthalimide (1979)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 17 (1979), S. 1153-1161

    ISSN: 0360-6376

    Topics: Chemistry and Pharmacology
    Notes: To elucidate mechanisms in electroinitiated polymerization reactions a comparison was conducted between ultraviolet (UV) photoinitiation and electroinitiation of N-vinyl phthalimide with zinc chloride as a catalyst. Both methods give low yields of a complex polymer product. A detailed analysis, infrared (IR), gel permeation chromatography (GPC), elemental, and molecular weight, conducted on the polymeric products, indicated that phthalimide ring opening was occurring and that complex mixtures of poly(N-vinyl phthalimide) derivatives were formed. Both initiation methods gave comparable results, which further indicated mechanistic similarity between photo-and electroinitiation in these donor-acceptor charge transfer polymerizations.

    Notes: As part of a program to extend the range of donor-acceptor-initiated polymerization processes, the electroinitiation of 2-vinylnaphthalene in a zinc chloride-sulfolane solution has been studied. Good conversion yields of well-characterized (NMR, IR, GPC, elemental analysis) poly(vinylnaphthalene) were obtained with the process showing several mechanistic similarities to other donor-acceptor salt electropolymerization systems.

    Electrochemically initiated polymerization of styrene with tetraalkyl and -aryl group VA halide support electrolytes (1977)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 15 (1977), S. 1555-1562 
    Details
    ISSN: 0360-6376
    Keywords: Physics ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: The electrochemically initiated polymerization of styrene in methylene chloride solvent with the use of platinum electrodes and tetraalkyl and -aryl group VA halides (i.e., quaternary ammonium, phosphonium, and arsonium compounds) as electrolyte has been investigated. The order of reactivity of the electrolytes with respect to polymerization rate and initiation efficiency was found to be: arsonium 〉 phosphonium 〉 ammonium. Mechanisms involving the electroreduction of the group VA quaternary halides to species capable of electroinitiating polymerization are postulated. The observed losses in solution conductivities during polymerization with the quaternary phosphonium and arsonium electrolytes indicate possible interaction between the initiating radical-ionic species and the supporting electrolyte. In an attempt to further elucidate the mechanism of initiation in these systems, a separate series of experiments, employing the nonpolymerizing monomer, 1,1-diphenylethylene, has been carried out.
