    The embryogenic potential of rice cell suspensions affects their recovery following cryogenic storage (1955)
    Springer
    Euphytica 85 (1955), S. 347-349 
    Details
    ISSN: 1573-5060
    Keywords: Oryza sativa L. cv. Taipei 309 ; rice ; cryogenic storage ; somatic embryogenesis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The rates of recovery from cryogenic storage of suspension cultures of the Japonica rice cultivar Taipei 309, as determined by the reduction of triphenyl tetrazolium chloride and cell regrowth, were significantly influenced by the embryogenic potential of the non-frozen cultures.

    Transformation studies in Hordeum vulgare using a highly regenerable microspore system (1955)
    Springer
    Euphytica 85 (1955), S. 113-118 
    Details
    ISSN: 1573-5060
    Keywords: Hordeum vulgare ; isolated microspores ; particle bombardment ; transformation

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A highly regenerable, isolated microspore system for barley, Hordeum vulgare L. cv. Igri, has been developed which is amenable to transformation studies using particle bombardment. The system allows DNA to be delivered to microspores at the single cell stage and both transient and stable transformation events have been demonstrated. The potential advantages of using isolated microspores as the target tissue in routine transformation systems are discussed.

    Transgenic barley by particle bombardment. Inheritance of the transferred gene and characteristics of transgenic barley plants (1955)
    Springer
    Euphytica 85 (1955), S. 81-88

    Notes: Summary Transgenic barley plants (Hordeum vulgare L. cv. Kymppi) were obtained by particle bombardment of various tissues. Immature embryos and microspore-derived cultures were bombarded with gold particles coated with plasmid DNA carrying the gene coding for neomycin phosphotransferase II (NPTII), together with plasmid DNA containing the gene for β-glucuronidase (GUS). Bombarded immature embryos were grown to plants without selection and NPTII activity was screened in small plantlets. One plant proved to be transgenic (T0). This chimeric plant passed the transferred nptII gene to its T1 progeny. The presence of the nptII gene was demonstrated by the PCR technique and enzyme activity was analyzed by an NPTII gel assay. Four T0 spikes and 15 T1 offspring were transgenic. The integration and inheritance was confirmed by Southern blot hybridization. Transgenic T2 and T3 plants were produced by isolating embryos from green grains of transgenic T1 and T2 plants, respectively and growing them to plants. After selfing, the ratio of transgenic to non-transgenic T2 offspring was shown to follow the rule of Mendelian inheritance. The general performance of transgenic plants was normal and no reduction in fertility was observed. Microspore-derived cultures were bombarded one and four weeks after microspore isolation. After bombardment, cultures were grown either with or without antibiotic selection (geneticin R or kanamycin). When cultures were grown without selection and regenerated plants were transferred to kanamycin selection in rooting phase, one out of a total of about 1500 plants survived. This plant both carried and expressed the transferred nptII gene. The integration was confirmed by Southern blot hybridization. This plant was not fertile.

    The phenotypic characterisation of R2 generation transgenic rice plants under field and glasshouse conditions (1955)
    Springer
    Euphytica 85 (1955), S. 395-401 
    Details
    ISSN: 1573-5060
    Keywords: Oryza sativa L. cv. Taipei 309 ; rice ; protoplasts ; direct DNA uptake ; kanamycin-resistant transgenic plants ; field trial ; glasshouse trial ; neomycin phosphotransferase II (npt II) gene ; gene expression and inheritance
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The phenotypes of seed progeny (R2 generation) of Oryza sativa L. cv. Taipei 309, which carried the neomycin phosphotransferase II (npt II) gene, were compared with those of non-transformed, protoplast-derived plants of the same generation and non-transformed, seed-derived plants under field and glasshouse conditions. Under both conditions the transgenic plants were generally smaller, took longer to flower and had reduced fertility. Significant differences were observed between individuals within the group of transgenic plants. The npt II gene was present in most of the transgenic plants, but NPT II activity was only detected in a minority of individuals.
