Summary: Tenebrio molitor satellite DNA has been analysed in order tostudy sequential organization of tandemly repeated monomers, i.e.to see whether different monomer variants are distributedrandomly over the whole satellite, or clustered locally. Analysedsequence variants are products of single base substitution in aconsensus satellite sequence, producing additional restrictionsites. The ladder of satellite multimers obtained after digestionwith restriction enzymes was compared with theoreticalcalculations and revealed the distribution pattern of particularmonomer variants within the satellite. A defined higher orderrepeating structure, indicating the existence of satellitesubfamilies, could not be observed. Our results show that somesequence variants are very abundant, being present in nearly 50%of the monomers, while others are very rare (0-1% of monomers).However, the distribution of either very frequent, or very raresequence variants in T. molitor satellite DNA is always random.Monomer variants are randomly distributed in the total satelliteDNA and thus spread across all chromosomes, indicating arelatively high rate of sequence homogenization among differentchromosomes. Such a distribution of monomer variants represents atransient stage in the process of sequence homogenization,indicating the high rate of spreading in comparison with the rateof sequence variant amplification.

Summary: Very abundant and homogeneous satellite DNA has been found in theflour beetle Palorus ratzeburgii, representing 40% of its genome.Sequencing of 14 randomly cloned satellite monomers revealed aconserved monomer length of 142 bp and an average A+T content of68%. Sequence variation analysis showed that base substitutions,appearing with the frquency of 2.3%, are predominant differencesamong satellite monomers. The satellite sequence is unique,without significant direct repeats and with only two potentiallystable inverted repeats. After electrophoresis of satellitemonomers on native polyacrylamide gel retarded mobilitiescharacteristic for curved DNA molecules are observed. Thecurvature profiles and DNA helix axis trajectory are calculatedon the bases of 3 different alghorithms. These calculationspredict that P. ratzeburgii satellite DNA forms left handedsolenoid superstructure. Comparison of described features withother satellite DNAs reveals some striking similarities withsatellite DNA from related species T. molitor, which belongs tothe same family of Tenebrionidae. Both satellites are veryabundant and homogeneous with the same, highly conserved monomerlength, although there is no homology at the nucleotide level.Their monomers, as well as multimers, exhibit very similarretarded electrophoretic mobilities. The calculated curvatureprofiles predict two band centers in monomers of each satellite,resulting in a model of left handed solenoid superstructures ofsimilar appearance.

Language: engleski
Summary: The chromosomes of Tribolium confusum have conspicious bulks ofpericentromeric constitutive heterochromatin. The amount ofheterochromatin measured by C-banding in metaphase chromosomes isestimated to be 40-45%. It is composed of an A+T rich DNAaccording to the distamycin A /diamidinophenylindol staining ofchromosomes. Restriction analysis of isolated T. confusum genomicDNA shows that this species has a satellite DNA that constitutesabout 40% of the genome. Cloning and sequencing experimentsreveal a monomer length of 158 bp and a copy number of 577,000per haploid genome. Its sequence is A+T rich (73%), with directand inverted repeat, one of them with a possibility of formingstable cruciform structure. The abundance, monomer length, andthe mutation rate are similar to those found in other satellitefamilies, from different species of Tenebrionidae, but nosequence homology has been found among them. No retarded mobilityof satellite DNA, characteristic for molecules with sequenceinduced curvature, has been detected by electrophoresis onnondenaturing polyacrylamide gels. In situ digestions withrestriction enzymes and in situ hybridization show that thissatellite DNA is located in pericentromeric positions of allchromosomes coinciding with C-bands.

Title: Analysis of divergence of Alphitobius diaperinus satellite DNA-roles of recombination, replication slippage and gene conversion

Language: engleski
Summary: Satellite DNA is highly abundant in Alphitobius diaperinus(Tenebrionidae, Coleoptera), comprising 25% of the total genomicDNA. Sequence analysis reveals an average GC content of 50.8% andthe presence of three different groups of satellite monomervariants, tH1, tH2 and tH3 with corresponding lengths of 123, 128and 126 bp. Their mutual homologies range between 65 and 81%.Sequence comparison shows that the monomer variant tH2 has beenformed by a recombination process between tH1 and tH3, which havea low average homology of only 65.15%. The longest stretch of100% homology between the recombining units is 17 bp and islocated 3' to the predicted recombination site. There is also anindication from sequence analysis that replication slippage andgene conversion play a part in the formation of satellite unitsand contribute to their divergence. The tH1, tH2 and tH3 monomervariants are organized in higher order repeating structures: adimer, composed of tH1 and tH3, and a trimer containing tH1, tH2and tH3 in series. The dimeric and trimeric repeat unitsfurthermore create three higher order satellite subfamilies. Twoof them contain either tandemly arranged dimers or trimers, whilethe third one is composed of both types of repeats, mutuallyinterspersed.
