In line with the `library' hypothesis, associated taxa share a library of different conserved satellite DNA sequences (distinctive satellite DNA households but in addition monomer variants or subfamilies of a satellite DNA family), which can be [http://www.new35.net.cn/comment/html/?32912.html 90  dose-dependent reduction within the {number of|quantity] differentially amplified in every single taxa.

Satellite DNA modifications because of gradual accumulation of sequence divergence which final results in divergence of satellite sequences in reproductively isolated groups of organisms (Plohl et al., 2012). Nonetheless, given the scattering of subfamilies in each and every lineage of Centaureinae, an option but not mutually exclusive hypothesis could explain this differential distribution. Based on the `library' hypothesis, related taxa share a library of distinctive conserved satellite DNA sequences (distinct satellite DNA households but also monomer variants or subfamilies of a satellite DNA family members), which may be differentially amplified in every taxa. Variability can remain for long evolutionary periods by decreased action of molecular mechanisms of non-reciprocal exchange, and sequence variants persist as a library (Mravinac et al., 2002; Mestrovic et al., 2006) from which any of them could be differentially amplified in every taxon with the subsequent replacement of a single sequence variant by one more in distinctive species.

This hypothesis has  ?been proved in insects (Mestrovic et al., 1998; Mravinac et al., 2002; Cesari et al., 2003; Pons et al., 2004) and plants ?(Navajas-Perez et al., 2009; Quesada del Bosque et al., 2011), and could clarify the principle observation made in Centaureinae concerning the scattering of HinfI types. Variation in satellite profiles is located in this case by modifications in copy quantity (Plohl et al., 2012).
