    Notes: Summary Hybrids of Triticum aestivum (monosomic 5D or ditelosomic 5DL) x T. speltoides (= Ae. speltoides) showed that the genotype of T. speltoides carries gene(s) which can partially compensate for the expected decrease in chromosome association at low temperatures (10°C) in the absence of chromosome 5D. In hybrids of T. aestivum (normal, ditelosomic 3DL or ditelosomic 3DL-monosomic 5D) x T. longissimum (= Ae. sharonensis), this compensation was not observed. In normal F1 hybrids of T. durum x T. longissimum partial chromosome association occurred at 10°C and this stabilizer effect may be explained by the presence of a Ltp-like gene on chromosome 5A. When a line of T. durum carrying a homozygous translocated 5B-5D chromosome was used in the crosses an even higher chromosome association was observed. These results suggest either the existence of a promoter gene for chromosome association in the 5D translocated segment or the loss of a weak suppressor gene in the removed segment of 5B. It was concluded that the translocated 5D segment did not carry the Ltp stabilizer gene.

    Notes: Abstract Double target in situ hybridization to root tip metaphase and interphase cells of Silene cintrana and Silene rothmaleri was used to allocate the position of 18S-5.8S-25S and 5S rRNA genes. In both species, the 18S-5.8S-25S rDNA probe labelled four sites located on the short arms of two submetacentric chromosomes. Only one locus for 5S rDNA was mapped adjacent to 18S-5.8S-25S genes in a subterminal position on the centromere side: in S. rothmaleri the 5S rDNA locus was adjacent to the small 18S-5.8S-25S locus while in S. cintrana it was near the large one. The NOR activity analysed by Ag-staining in metaphase cells revealed proportionality between in situ labelling dimensions and Ag-NORs. In both species all rDNA loci were potentially active, although in S. rothmaleri a tendency for the expression of only one locus was observed. Interphase organisation analysis of rDNA showed some differences between both species that were correlated with NOR activity.
