These subfamilies were established based on a set of diagnostic Ing from different habitats including endolith, hypolith, lithoautotroph, metalotolerant, oligotroph positions given by a specific mutation shared by all of the sequences of one particular group (Fig. -- HinfI satellite DNA evolution in Centaureinae Figure 2 shows the distribution of HinfI subfamilies among species.

Additionally, current] belonging to subfamilies I, II and III, some with sequences of two or the 3 subfamilies coexisting inside the exact same species. In each Rhaponticoides spp. analysed, sequences belonged either to subfamily I or to subfamily II, with one sequence of R. linaresii belonging to subfamily III. analysed had sequences of subfamilies I, II and III and, additionally, we found up to six (out of 13) repeats of subfamily VII in C.Omogenized in a genome and fixed within a population at a greater price than that at which they arise. This method outcomes in speedy divergence of satellite sequences in reproductively isolated groups of organisms (Plohl et al., 2012). Nonetheless, the general variability profile of satellite DNA monomers within a genome is a complex feature that will depend on genomic conservation and divergence of satellite DNAs, distribution and homogenization patterns among variants, putative selective constraints imposed on them, reproduction mode and population variables (Plohl et al., 2010, 2012). For that reason, concerted evolution might be slowed down because of satellite DNA place, organization and ?repeat-copy number (Navajas-Perez et al., 2005, 2009), functional constraints (Mravinac et al., 2005) or biological aspects (Luchetti et al., 2003, 2006; Robles et al., 2004; ?Suarez-Santiago et al., 2007a).Amplified products had been sequenced to confirm their subfamily provenance. R E S ULT S The primer pairs CenHinf1 and CenHinf2 had been made use of for the amplification of HinfI repeats from the genomes of 38 species, the PCR solutions had been cloned and 502 HinfI cloned repeats were sequenced. These repeats had been ascribed to eight monomer types or subfamilies. These subfamilies had been established in accordance with a set of diagnostic positions offered by a distinct mutation shared by each of the sequences of one group (Fig. 1). They had been designated with Roman numerals from I to VIII following the no?menclature previously employed in Suarez-Santiago et al. (2007a) for 3 of them (subfamilies I, II and III). Additionally, the distinctive varieties of sequences have diagnostic deletions identified at various positions in the HinfI repeats. To study diversity distribution along the repeat sequences, a sliding window evaluation wasQuesada del Bosque et al. -- HinfI satellite DNA evolution in Centaureinae Figure two shows the distribution of HinfI subfamilies amongst species. Species of Centaurea and Rhaponticoides were characterized by the presence in their genomes of the HinfI sequences belonging to subfamilies I, II and III, some with sequences of two or the three subfamilies coexisting in the exact same species. In each Rhaponticoides spp. analysed, sequences belonged either to subfamily I or to subfamily II, with one sequence of R. linaresii belonging to subfamily III. In the case of Centaurea, subfamilies I and II had been found in all species of subgenus Centaurea, with the presence of subfamily III in two species.
