... diameter of NORs of triploid was no significant different from that of diploid ( p > 0.05). Additionally, 5S rDNA localization to 3 submetacentric chromosomes was observed in triploids, compared to 2 submetacentric chromosomes in diploids. The number of 18S rDNA sites displayed positional conservancy...

... libraries, which permitted simultaneous identification of all chromosomes of F. vesca . Moreover, 45S and 5S rDNA were mapped to chromosomes 1, 2, and 7, respectively. A karyotype of metaphase chromosomes was constructed, representing the first FISH-based molecular cytogenetic karyotype of F. vesca . Our...

..., TTAGGG n sequence and non-LTR retrotransposon family members Rex1, Rex3 and Rex6 showed that non-LTR elements may be dispersed in the chromosome set with relative concentration in heterochromatic regions, as shown by Rex1 , or may even intercalate in 45S rDNA and the telomeric sequence, as found for Rex3...

...-temperature effects on subtelomeric repetitive sequences (pSc200) and 45S rDNA in rye seedlings submitted to 40°C during 4 h. Chromatin organization patterns were evaluated through fluorescent in situ hybridization and transcription levels were assessed using quantitative real-time PCR. Additionally...

... authors. Interestingly, many of the distal chromosome segments in T. virginiana possess duplicated subterminal telomere clusters, heterochromatin, 5S and 45S rDNAs orderly intermixed and share this complex cytomolecular architecture with the common type of a B chromosome. Based on the obtained results...

... to the β-complex of the ring-forming rhoeos. In spite of some modifications in the arrangement of a few distal rDNA sites and in the amount of pericentromeric AT-rich heterochromatin, the alethal genome of the bivalent-forming Rhoeo seems segmentally unaltered. Thus, the breakdown of balanced lethals...
