    Notes: [Auszug] THE discovery of viable seeds of rare plants in the soils of sites where they had previously been considered extinct brings into question the definition of extinction for the plant kingdom1. In the fenlands of East Anglia in Britain, the fen ragwort (Senecio paludosus) and the fen violet (Viola ...

    Notes: [Auszug] WINDS of hurricane force (with wind speeds in excess of 33.5 metres per second) are rare in the British Isles, but the storms of last year raised important ecological questions. Of particular interest is the influence of such rare catastrophes on natural woodlands. New studies of forest recovery in ...

    Notes: [Auszug] THERE are few terms that have caused more controversy among botanists than 'vegetation'. Vegetation may unite plants, but it certainly divides plant scientists. The main debate is to do with whether plant species behave in an independent, individualistic way, each distributed according to its own ...

    Notes: [Auszug] THE recent conclusion by Blake and Rowland1 that the concentration of methane in the troposphere has risen by 11 per cent in the past 9 years, and the proposal of Pearman and Fraser2 that levels have doubled in the past century, are timely reminders of the importance of this gas in the atmosphere. ...

    Notes: [Auszug] THERE are occasions when words fail us; one word which is quite inadequate when applied to the plant kingdom is 'migration'. It generates visions of weary herds of wildebeest or caribou, or of swallows on telephone wires, but in the plant world it has come to mean something quite different. Rather ...

    Notes: [Auszug] COCK ROBIN has nothing on the Quaternary megafauna when it comes to murder mysteries. The debate still rages concerning the relative roles of climatic change and human activities in the rash of extinctions of large herbivores and carnivores during the early part of the current interglacial, and ...

    Notes: [Auszug] THE disposal of human sewage raises ecological problems which are still far from being solved. Sewage sludge, a potentially toxic waste, must be removed from the centres of population where it is produced, rendered harmless and dis-posed of, often by incineration or by dumping as a land fill. But ...

    Induction of homologous recombination in Saccharomyces cerevisiae (1988)
    Springer
    Molecular genetics and genomics 214 (1988), S. 37-41 
    Details
    ISSN: 1617-4623
    Keywords: Homologous recombination ; UV induction ; Yeast
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary We have investigated the effects of UV irradiation of Saccharomyces cerevisiae in order to distinguish whether UV-induced recombination results from the induction of enzymes required for homologous recombination, of the production of substrate sites for recombination containing regions of DNA damage. We utilized split-dose experiments to investigate the induction of proteins required for survival, gene conversion, and mutation in a diploid strain of S. cerevisiae. We demonstrate that inducing doses of UV irradiation followed by a 6 h period of incubation render the cells resistant to challenge doses of UV irradiation. The effects of inducing and challenge doses of UV irradiation upon interchromosomal gene conversion and mutation are strictly additive. Using the yeast URA3 gene cloned in non-replicating single- and double-stranded plasmid vectors that integrate into chromosomal genes upon transformation, we show that UV irradiation of haploid yeast cells and homologous plasmid DNA sequences each stimulate homologous recombination approximately two-fold, and that these effects are additive. Non-specific DNA damage has little effect on the stimulation of, homologous recombination, as shown by studies in which UV-irradiated heterologous DNA was included in transformation/recombination experiments. We further demonstrate that the effect of competing single- and double-stranded heterologous DNA sequences differs in UV-irradiated and unirradiated cells, suggesting an induction of recombinational machinery in UV-irradiated S. cerevisiae cells.
