    Ascorbate potentiates serum-induced S phase entry of quiescent 3T3 cells (1992)
    Springer
    Protoplasma 169 (1992), S. 85-87 
    Details
    ISSN: 1615-6102
    Keywords: Ascorbate ; S phase ; BALB/c 3T3 cells

    Topics: Biology
    Notes: Summary Arrested BALB/c 3T3 cells were induced to the G0-G1 transition by fetal calf serum (FCS) and S phase entry was measured by [3H]thymidine incorporation as an index of DNA synthesis. [3H]Thymidine uptake was proportional to FCS concentration. Ascorbate (ASC) itself was unable to increase DNA synthesis in these cells but potentiated it in the presence of both 1% and 10% FCS. [3H]Thymidine uptake profile was similar with and without ASC, and showing at 24 h an ASC stimulation of 69% in the presence of 1% FCS and 58% with 10% FCS. These data are discussed in reference to the participation of ASC on plasma membrane energization for membrane translocations and transport.

    Karyology and evolution inSesamoides (Resedaceae) (1981)
    Springer
    Plant systematics and evolution 139 (1981), S. 147-154 
    Details
    ISSN: 1615-6110
    Keywords: Resedaceae ; Sesamoides ; Meiosis (PMC) ; meiotic abnormalities ; size and fertility of pollen ; autopolyploidy ; chromosome base number
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The meiotic behaviour abnormalities, fertility and size of pollen of 6 taxa ofSesamoides have been analysed. Besides diploids (2x), polyploids (4x, 6x, 8x) have been found. The chromosome base number is x = 10, but an origin from x = 5 is suggested.

    The nature of polyploidy inReseda sect.Leucoreseda (Resedaceae) (1983)
    Springer
    Plant systematics and evolution 142 (1983), S. 223-237

    ISSN: 1615-6110
    Keywords: Angiosperms ; Resedaceae ; Reseda ; DNA values ; meiotic analysis ; seed protein and esterase isozyme electrophoresis ; polyploidy

    Topics: Biology
    Notes: Abstract We have found two chromosome levels (n = 10 and n = 20) in Spanish species ofReseda sect.Leucoreseda, four species on the first (R. undata, R. paui, R. suffruticosa, R. barrelieri), only one on the second level (R. alba). As already the species with n = 10 apparently behave as polyploids, we propose x = 5 as the original basic chromosome number for this section. The seed protein profile ofR. alba (2n = 40) reveals close relationships withR. undata (2n = 20), while the esterase isozymes suggest affinities withR. paui (2n = 20). Thus,R. alba can be regarded either as an autopolyploid fromR. paui or more likely as an allopolyploid fromR. paui andR. undata. Finally, the DNA values suggest a diploidization process inR. alba since its origin.
