    Vocal cord paralysis in the Shy-Drager syndrome (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 46 (1991), S. 0 
    Details
    ISSN: 1365-2044
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: A case is presented in which unexpected and persistent postoperative respiratory problems led to the finding of bilateral abductor vocal cord paralysis and confirmed the diagnosis of the Shy-Drager syndrome. Anaesthetists should be aware that vocal cord paralysis may be a feature of this uncommon condition, and should consider the possibility of glottic obstruction as a cause of ventilatory difficulties.

    Carbon dioxide blocks the stigma callose response following incompatible pollinations in Brassica (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 7 (1984), S. 0 
    Details
    ISSN: 1365-3040
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract. Carbon dioxide is known to overcome sporophytic self-incompatibility in Brassica. Elevated CO2 (30 mmol CO2 mol-1 air), supplied via a flowthrough gas system, was shown to block the formation of rejection callose in the surface stigmatic papillae of Brassica campestris var. T15 following self-pollination. Possible mechanisms by which CO2 may affect callose formation are discussed.

    Clonal propagation of Trifolium Pratense, T. Resupinatum and T. Subterraneum by direct somatic embryogenesis on cultured immature embryos (1986)
    Springer
    Plant cell reports 5 (1986), S. 165-168 
    Details
    ISSN: 1432-203X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Direct somatic embryogenesis on immature zygotic embryos in vitro has been confirmed for Trifolium pratense and extended to T. resupinatum and T. subterraneum. For all species direct embryo cloning can be achieved on an appropriate basal medium supplemented with 1gl−1 yeast extract and 0.05 mgl−1 BAP. Basal medium/sucrose formulation, level of yeast extract and level of BAP affected the nature of in vitro responses. In particular, for T. pratense and T. subterraneum lowering of the yeast extract level suppressed embryoid initiation, and raising of the BAP level stimulated formation of nodular morphogenic callus. For T. resupinatum alteration of the basal medium/sucrose formulation changed the tissue site of embryoid initiation from hypocotyl to cotyledons or both. Control of embryoid initiation is briefly discussed.

    Agrobacterium induced gall formation in bell pepper (Capsicum annuum L.) and formation of shoot-like structures expressing introduced genes (1990)
    Springer
    Plant cell reports 9 (1990), S. 360-364 
    Details
    ISSN: 1432-203X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The objective of this research was to define an in vitro regeneration and transformation system for bell pepper (Capsicum annuum L.) using six cultivars and one Guatemalan wild accession. The wild accession exhibited the best regeneration response. Only occasional elongation of shoot buds in ‘Yolo Wonder L’ was achieved by culture in the dark on a medium containing 10 mg/l BA and l mg/l IAA. Transformed shoot buds and leaf-like structures were obtained, showing beta- glucuronidase activity predominantly in the vascular and perivascular tissues, with no indication of contaminating Agrobacterium in the tissues. Attempts to regenerate whole transgenic plants from transformed shoot buds were unsuccessful.

    Self-incompatibility in Acacia retinodes: Site of pollen-tube arrest is the nucellus (1986)
    Springer
    Planta 169 (1986), S. 245-250 
    Details
    ISSN: 1432-2048
    Keywords: Acacia ; Nucellus ; Ovule ; Pollen tube arrest ; Sell-incompatibility
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract In self-incompatible Acacia retinodes Schldl. var. uncifolia J.M. Black there is no inhibition of self pollen tubes before entry into the ovule, but the frequency of fertilized embryo sacs observed after self pollination is only 0.09–0.24 of that observed after outcrossing. Fluorescence- and light-microscope studies of sectioned, squashed or cleared whole ovules indicate that most self pollen tubes are arrested within the first or second layer of cells of the nucellus. The probability that nucellar arrest represents a primitive feature of self-incompatibility is discussed.

    Recovery of primary transformants of soybean (1989)
    Springer
    Plant cell reports 7 (1989), S. 615-617 
    Details
    ISSN: 1432-203X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Three transformants of soybean, Glycine max (L.) Merr., have been recovered among a total of 18 plants regenerated by somatic embryogenesis from immature cotyledon tissues after cocultivation with Agrobacterium strains carrying a 15 kD zein gene (pH5PZ3D). DNA from upper leaves hybridized to a synthetic RNA probe specific for the zein sequence at a level equivalent to at least one copy per haploid genome. Hybridization to a vir G/C probe, however, was negligible, indicating that sequestration of whole bacteria or even persistence of plasmids within the tissues could not account for the zein hybridization signals. Progeny of all plants were uniformly untransformed. Since most somatic embryos have a multicellular origin in the regeneration system used, it is believed that the primary transformants were chimeric. The results indicate that somatic embryogenesis may be adaptable to Agrobacterium-mediated transformation in soybean, but that greater numbers of mitotic cycles under selection before embryo initiation will be required if somatic embryogenesis is to be used efficiently for production of plants with transformed germ-line cells.

    Analysis of lipid composition and morphological characteristics in soybean regenerants (1989)
    Springer
    Plant cell reports 7 (1989), S. 701-703 
    Details
    ISSN: 1432-203X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A study was conducted to examine the extent of somaclonal variation of soybean plants, Glycine max (L.) Merrill cv. ‘McCall’, regenerated via somatic embryogenesis from cultured immature cotyledons using two different protocols. The sexual progeny of regenerants were compared with normal, seed-derived populations for morphological characteristics and fatty acid composition of seeds. First generation progeny of regenerants showed greater phenotypic variation than the control population, but this variation was not observed in the second generation. No stable somaclonal variants for fatty acid composition of the seed oil or morphological characteristics were observed, indicating that this somatic embryogenesis system should be adaptable for transformation with minimal generation of unwanted variation.

    The effect of isolated components of Prunus avium L. styles on in vitro growth of pollen tubes (1982)

    Notes: Abstract A number of components isolated from styles of P. avium cv. Napoleon (S 3 S 4) have been tested for their capacity to influence in vitro growth of pollen tubes from fresh and stored pollen (cv. Napoleon (S 3 S 4)). An antigenic glycoprotein (Antigen S) is a potent inhibitor of in-vitro pollen tube growth, causing a 65% reduction in tube length at a concentration of 20 μg/ml. None of the other style components were effective inhibitors of pollen tube growth; neither were proteins of animal origin such as histone, serum albumin, cytochrome C, and the glycoproteins ovalbumin and thyroglobulin, effective inhibitors.

    Notes: Abstract The identification, isolation and aminoterminal sequencing of two S-genotype-associated proteins from style extracts of Lycopersicon peruvianum Mill. is reported. There is a high level of homology between these two sequences and with the amino-terminal sequences of other S-allele-associated glycoproteins isolated from Nicotiana alata Link et Otto. These sequences were obtained by a new high-sensitivity method of selected twodimensional gel analysis followed by electroelution and purification of proteins by inverse-gradient high-performance liquid chromatography before sequencing.
