    10Be and 9Be isotopes composition of Mn nodule 44 TKD and Mn crust 40 TKD retrieved in the South China sea during expedition SO23/2 (R/V Sonne) (2023)

    Publication Date: 2023-08-28
    Description: During the campaign SO23/2 (R/V Sonne) in the South China sea various manganese deposits were retrieved by dredging. Two representative samples were selected for chemical analysis: one Mn crust (0.4 cm thick) attached to a vesicular olivine basalt fragment for station 40KD and one irregular spheroidal shaped Mn nodule with rough surface and a Miocene chalk core for station 44KD. Their chemical composition was determined by X-ray fluorescence analysis on the grounded bulk sample.

    The development of a negative selection system for the isolation of plant temperature-sensitive auxin auxotrophs (1988)
    Springer
    Theoretical and applied genetics 75 (1988), S. 869-874 
    Details
    ISSN: 1432-2242
    Keywords: Auxin ; Auxotrophs ; BUdR ; Enrichment ; Temperature sensitivity

    Topics: Biology
    Notes: Summary A protocol has been developed for the negative selection of plant auxotrophs using the nucleoside analogues BUdR and FUdR. The protocol was optimised using nitrogen-starved protoplast-derived cells of Nicotiana plumbaginifolia to simulate auxotrophy. The present results represent a significant improvement over previous reports in that: 1) The background of colonies escaping BUdR/FUdR kill is low and reproducible. 2) The protocol was improved to the point where background survival was 0.03% for non-starved cultures and 0.09% for auxin-starved cultures. 3) It was shown that UV irradiation decreases BUdR sensitivity of dividing cells and that this is overcome by increased exposure to BUdR. 4) Application of the method to auxin-starved haploid protoplast-derived cell suspensions resulted, for the first time, in the selection of temperature-sensitive (ts) auxin auxotrophs. 5) It could be demonstrated, for the first time, that the method in practice enriches for auxotrophs, in this case by a factor of 10 for auxin auxotrophs and at least 60 for ts auxin auxotrophs.
