    ...and can differ significantly in nucleotide sequence and copy number of their repeats even between related species. The main theories explaining the evolution of satDNAs were proposed at a time when, due to methodological limitations, only the most abundant satellites were discovered in s. In line...

    ...of their dynamics characterized by repeated bursts of satDNAs spreading through euchromatin, followed by a process of elongation and homogenization of arrays. We find that suppressed recombination on the X Chromosome has no significant effect on the spread of satDNAs but the X rather tolerates the amplification...

    .... A common genomic feature of these regions is the enrichment of long arrays of near-identical tandem repeats, known as satellite DNAs, which offer a limited number of variant sites to differentiate individual repeat copies across millions of bases. This substantial sequence homogeneity challenges available...

    ...introduce and homogenize new sequence variants into tandem repeat arrays. We found evidence for the putative involvement of sequence conversion within the assembled C57BL/6J Ymin array, with at least 200 bp of Ymin DNA undergoing conversion to produce a ‘‘variant’’ HOR unit (Supplemental Fig. S9). The unit...

    ...examples like histone genes (Maxson et al. 1983), rDNA arrays (Hall et al. 2022), and immunoglobulin genes (Watson and Breden 2012). Tandem repeats are prone to rapid copy number changes mediated through mechanisms such as unequal crossing over, replication slippage, gene conversion, and intrachromatid...

    ...that this physical proximity may promote nonhomologous recombination or conversion events leading to an evolutionary homogenization of α-satellite as well as other pericentromeric DNA ( Choo et al. 1988 ; Greig et al. 1993 ). Our data may suggest that the pericentromeric regions of many other nonacrocentric...

    ...et al. 1997), where high frequency CEN178 variants are found in the center, rather than the edges, of the centromeric arrays (Wlodzimierz et al. 2023b). Concerted evolution of satellites implies that an active process of DNA breakage and homologous recombination occurs within the center of the arrays...

    ...clonality. Generally, rDNA tandem repeats are thought to undergo concerted evolution toward sequence homogenization via repeated homologous recombination, namely, unequal crossovers and gene conversion (Symonová 2019; Mullis et al. 2020; Garcia et al. 2024). Because Pst104E has genetically distinct nuclei...

    ...1999 ). Unlike the NHEJ models, the HR models predict that after a DNA DSB, a homologous region is used as a template to initiate the repair. At least three different mechanisms of HR have been proposed to repair mitotic cells: gene conversion, single-strand annealing, and break-induced recombination...
