    Notizen: 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.

    Thema: Biologie
    Notizen: Abstract Lemna minor fronds transferred to a sterile culture medium containing 50% (v/v) deuterium oxide (2H2O) rapidly undergo a loss of soluble protein with a corresponding increase in free amino acids. The loss of protein is due to two factors: (i) the inhibition of protein synthesis for 4 h followed by a slower rate of synthesis than normal, (ii) a rapid 9–10 fold increase in protein degradation. In plants grown for longer periods (3–6 days) in 50% 2H2O medium, protein synthesis is inhibited by 20% and the rate constant of degradation is 2–3 times that measured in fronds growing in normal (H2O containing) complete medium. The initial loss of protein is not due to the breakdown of any specific protein fraction. Investigation of several enzymes indicates that all proteins are catabolised in response to 2H2O treatment. The implications of these results with regard to the interpretation of density-labelling experiments are discussed.

    Thema: Biologie
    Notizen: Abstract Transfer of Lemna minor fronds to culture medium containing 50% (v/v) deuterium oxide induces a large increase in the rate of protein breakdown, which is not due to an increase in the activity of acidic or neutral proteolytic enzymes or peptidases. Biochemical and ultrastructural evidence indicates that deuterium oxide affects the properties of certain membranes, particularly the tonoplast, and allows vacuolar proteolytic enzymes to pass into the cytoplasm and cause the increased protein breakdown.

    Thema: Biologie
    Notizen: 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.

    Notizen: 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.

    Thema: Biologie
    Notizen: 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.

    Notizen: 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.
