    Genetics of seed storage proteins in the love tree Cercis siliquastrum L. (Fabaceae) (1994)

    Notes: Abstract The patterns of C. siliquastrum seed storage proteins (“cercins”) are described using SDS-polyacrylamide gel electrophoresis. The polypeptides detected had very different molecular weights (ranging from 168 to 34 KDa) which, together with their high homogeneity, produced a very good resolution of bands. These proteins could be ascribed to five different loci. The analysis of seed sets of individual trees indicated that the love tree is almost completely autogamous with less than 5% of outcrosses. Although this mode of reproduction seems to produce a decrease in heterozygote frequency among the seeds of the population analysed, the levels of variability detected were very high for an autogamous plant: all of the loci were polymorphic, with a mean heterozygosity of 0.327 and a polymorphic index of 0.412. Protein segregation revealed a strong genetic linkage between three cercin loci (a, c and d) while the other two are independent.

    Vegetation changes along a precipitation gradient in Central Argentina (1993)
    Springer
    Plant ecology 109 (1993), S. 5-14 
    Details
    ISSN: 1573-5052
    Keywords: Chaco vegetation ; Humidity gradient ; Monte vegetation ; Physiognomic plant characters ; Vegetation structure
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Changes in vegetation along a precipitation gradient in Central Argentina were studied. Floristic samples were taken along an east-west transect of about 300 km. Correlation analysis between precipitation and ordination axes was used to provide an environmental interpretation of vegetation variability. Floristic analysis produced an ordination of plant communities from evergreen forests (precipitation 〉500 mm) to desert shrublands and therophyte communities (precipitation 〈200 mm). Results showed a trend of floristic and structural impoverishment towards the west. There is a replacement of species along the transect and a shift in dominant growth forms. The first ordination axis is significantly, negatively correlated with annual precipitation.

    Halogenated poly-(N-vinylcarbazoles): flexibility and viscometric constants (1991)

    ISSN: 1435-1536
    Keywords: 3-Cl-N-vinylcarbazole ; 3-Br-N-vinylcarbazole ; monomericunitprojectionlength ; viscometricconstants

    Notes: Abstract N-vinylcarbazole, 3-Cl-N-vinylcarbazole, and 3-Br-N-vinylcarbazole were homopolymerized via radical polymerization. Several monodispersed samples of respective polymers were obtained by fractionation and their intrinsic viscosities were measured in tetrahydrofurane at 25°C. The viscometric constantsK anda, the monomeric unit projection length ℏ, and the flexibility parameter λ were determined using the gel permeation chromatography technique to determine the elution volumeVe and apply a newly derived relationship between the flexibility parameter and molecular weight. The presence of halogen atoms in the carbazole group of PNVC varies the value of ℏ and, consequently, the rigidity of the polymer.
