The purple saxifrages, Saxifraga sect. Porphyrion subsect. Oppositifoliae, comprise the closest relatives of the arctic-alpine model plant S. oppositifolia and have a centre of diversity in the central and southern European mountain ranges. A multitude of taxa has been described and taxonomic concepts vary among different treatments. Using amplified fragment length polymorphism (AFLP) fingerprinting we show that some taxa indeed form strongly supported genetic entities best recognized on the species level (S. biflora, S. blepharophylla, S. retusa, S. rudolphiana, S. speciosa), while others (S. murithiana, S. paradoxa) are not genetically divergent at all. Saxifraga oppositifolia s. s. is phylogenetically incoherent. Plastid DNA sequence data show very limited congruence with the predominantly nuclear-derived AFLPs. Several co-distributed taxa (S. biflora, S. blepharophylla, S. oppositifolia s. s., S. retusa) share the same set of haplotypes. In the widespread species S. oppositifolia and S. retusa, highly ... : Plastid DNA sequences of Saxifraga oppositifolia s.l.Combined alignment of plastid DNA sequences (psbA-trnH, trnT-trnF) of Saxifraga oppositifolia s.l. The alignment was created using BioEdit. First column: individual name containing population number and taxon abbreviation (aug = S. retusa subsp. augustana, bif = S. biflora subsp. biflora, ble = S. oppositifolia subsp. blepharophylla, opp = S. oppositifolia subsp. oppositifolia, par = S. oppositifolia subsp. paradoxa, rud = S. oppositifolia subsp. rudolphiana, ret = S. retusa subsp. retusa, spe = S. oppositifolia subsp. speciosa), second column: aligned sequences.SaxOppSL_plastidSeqs_alignment.txtAFLP matrix of Saxifraga oppositifolia s.l.Manually scored AFLP matrix of Saxifraga oppositifolia s.l. using DAx (Van Mierlo Software Consultancy, Eindhoven) with non-reproducible and homogeneous fragments removed. AFLP data were generated following the procedure of Vos et al. (1995) with the modifications described by Schönswetter et al. (2009) using three primer ...
