    Notizen: Abstract —The choice of the regions is essential in the application of the algorithm CN, therefore a seismotectonic criterion for their definition is tested. In order to take into account the geodynamic complexity characterising the Italian peninsula, we established to strictly follow the seismotectonic zones, including in each region only zones with similar seismogenic behaviour and the transitional zones connected to them. Three regions have been successfully defined in this way, corresponding approximately to the North, Centre and South of Italy. The reduction of the space-time uncertainty and the increase of the stability of prediction results obtained with this regionalisation, with respect to the previous applications of CN in Italy (Keilis-Borok et al., 1990; Costa et al., 1995, 1996), can be interpreted as a validation of the seismotectonic model.

    Notizen: Abstract  The aim of this study was to clarify the inheritance of the nuclear ribosomal DNA (rDNA) in the ectomycorrhizal basidiomycete Laccaria bicolor S238N in order to resolve inter- and within-strain relationships in forest ecosystems. PCR amplification of the intergenic spacer (IGS) was carried out in the dikaryotic mycelium and its haploid progeny. In the dikaryotic mycelium, multiple amplification products were produced for the 25s/5s (IGS1) and 5s/17s (IGS2) intergenic spacers. The 4.5- and 4.0-kb fragments of IGS2 (haplotypes α and β, respectively) were observed to occur in a 1:1 ratio within the haploid progeny as a result of divergent IGS haplotypes in the two separate nuclei. Recombinant monokaryons having both types of IGS2 occurred at a low frequency (6.5%; 60 kb per centimorgan) during meiosis. Haplotypes α and β of IGS1 cross-hybridized forming heteroduplexes during the PCR temperature cycle. The two IGS1 haplotypes differed only by the repeat number of a TA2C3 motif and co-segregated with the IGS2 haplotypes. Heteroduplex formation and IGS polymorphism provide information that is helpful in distinguishing between introduced exotic L. bicolor S238N and indigenous populations of Laccaria spp. in forest ecosystems.
