    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

    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.

    A simple system for pea transformation (1997)

    Plant cell reports 16 (1997), S. 513-519

    ISSN: 1432-203X
    Keywords: Key wordsAgrobacterium tumefaciens ; Pea transformation ; Cotyledonary meristem ; Bar gene ; Phosphinothricin resistance

    Topics: Biology
    Notes: Abstract The lateral cotyledonary meristems of germinating Pisum sativum cv. Puget seeds were used to develop a reproducible Agrobacterium tumefaciens-mediated trans-formation system. This procedure exhibits distinct advantages over those previously reported, in that it uses dry seed as starting material, and the highly regenerable cotyledonary meristems rapidly produce transgenic shoots without an intermediate callus phase. This transformation regime facilitates the rapid generation of phenotypically normal, self-fertile plants containing functional transgenes inherited in a Mendelian fashion.

    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.

    Organization and mapping of legumin genes in Pisum (1986)
    Springer
    Molecular genetics and genomics 202 (1986), S. 280-285

    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.

    Topics: Biology
    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 cytology of cotyledon cells and the induction of giant polytene chromosomes inPisum sativum (1979)

    ISSN: 1615-6102

    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.

    1H and 13C NMR assignment of maltitol by a combination of 2D NMR and H/D isotope effects on nuclear shielding (1988)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 26 (1988), S. 425-429 
    Details
    ISSN: 0749-1581
    Keywords: Maltitol ; 13C NMR assignment ; 2D-INADEQUATE ; SIMPLE NMR ; DIS NMR ; 1H NMR assignment ; 1H-13C COSY NMR ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Maltitol was assigned unequivocally without any need for reference to model compounds by a combination of 2D, SIMPLE (secondary isotope multiplets of partially labelled entities) and DIS (differential isotope shift) NMR techniques. The combination of these three techniques is very powerful for the assignment of molecules with many exchangeable hydrogen atoms, such as carbohydrates. In the case of maltitol a complete 13C NMR assignment was achieved in three solvents [H2O, D2O and (CD3)2SO] using three experiments. A 1H-13C 2D correlation experiment allowed the 1H NMR spectrum to be assigned unequivocally for the first time.
