    Watering converts a CAM plant to daytime CO 2 uptake (1976)

    Notes: [Auszug] We investigated the results of giving CAM plants an adequate water supply, thereby obviating the need for water conservation and show that this leads to their conversion to daytime CO2 uptake. We used Agave deserti Engelm. (Agavaceae) plants, which are common in the sandy soils of the Colorado, ...

    BrdU-33258 Hoechst analysis of DNA replication in human lymphocytes with supernumerary or structurally abnormal X chromosomes (1976)

    Notes: Abstract BrdU-33258 Hoechst techniques have been used to characterize DNA replication patterns in lymphocytes from human females with supernumerary or structurally abnormal X chromosomes. Fluorescence analysis permits identification of late replicating X chromosomes in a very high proportion of cells and affords a high resolution method for determining the interchange points of X-X and X-autosome translocations. Asynchrony among terminal replication patterns of multiple late replicating X chromosomes within an individual cell can occasionally be demonstrated. The arms of isochromosomes usually exhibit symmetrical fluorescence patterns, with replication terminating in bands Xq21 and Xq23 (predominant pattern) or in bands Xq25 and Xq27 (alternative pattern) in both arms. In the vast majority of lymphocytes containing a balanced X-13 or X-19 translocation, the normal X is late replicating. However, DNA synthesis in the translocation products occasionally appears somewhat delayed relative to that expected for an early replicating X, consistent with possible position effects on replication kinetics.

    Expression of the human adenylate kinase isozymes, phosphopyruvate hydratase, 6-phosphogluconate dehydrogenase, and phosphoglucomutase-1 in man-rodent somatic cell hybrids (1976)
    Springer
    Biochemical genetics 14 (1976), S. 1-17

    ISSN: 1573-4927
    Keywords: adenylate kinase isozymes ; phosphopyruvate hydratase ; 6-phosphogluconate dehydrogenase ; phosphoglucomutase-1 ; chromosome 1 ; man-rodent somatic cell hybrids

    Notes: Abstract The expression of the adenylate kinase isozymes and of phosphopyruvate hydratase was studied in man-mouse and man-hamster hybrid clones. Concordant segregation of the loci coding for AK-2 and PPH was observed in 54 of 55 primary hybrid clones, and these loci were demonstrated to be synthetic with the loci specifying PGM-1 and PGD. The pattern of expression of the four enzymes in discordant clones suggests the gene order 1pter-(PGD,PPH)-AK-2-PGM-1-centromere. In addition, AK-1 was found to be expressed independently of AK-2.

    Improved techniques for the induction of mammalian cell hybridization by polyethylene glycol (1976)
    Springer
    Somatic cell and molecular genetics 2 (1976), S. 165-176

    Notes: Abstract Modifications in the techniques for the induction of mammalian somatic cell hybridization by polyethylene glycol (PEG) have led to procedures that are rapid, simple, and effective. The basic improvements, for both monolayer and suspension fusions, are a short exposure to PEG and a rapid dilution of PEG following treatment. There is a marked effect of PEG concentration on cell hybridization, and there seem to be inherent differences between cells in terms of the extent of cell fusion induced by PEG.
