On the Evolutionary and Biogeographic History of Saxifraga sect. Trachyphyllum (Gaud.) Koch (Saxifragaceae Juss.)
Arctic-alpine plants in the genus Saxifraga L. (Saxifragaceae Juss.) provide an excellent system for investigating the process of diversification in northern regions. Yet, sect. Trachyphyllum (Gaud.) Koch, which is comprised of about 8 to 26 species, has still not been explored by molecular systematists even though taxonomists concur that the section needs to be thoroughly re-examined. Our goal...
متن کاملTales of the unexpected: phylogeography of the arctic-alpine model plant Saxifraga oppositifolia (Saxifragaceae) revisited.
Arctic-alpine biota occupy enormous areas in the Arctic and the northern hemisphere mountain ranges and have undergone major range shifts during their comparatively short history. The origins of individual arctic-alpine species remain largely unknown. In the case of the Purple saxifrage, Saxifraga oppositifolia, an important model for arctic-alpine plants, phylogeographic studies have remained ...
متن کاملMicrosatellite primers for the gynodioecious grassland perennial Saxifraga granulata (Saxifragaceae)1
UNLABELLED PREMISE OF THE STUDY Nine polymorphic and 12 monomorphic microsatellite loci (simple sequence repeats [SSRs]) were isolated and characterized for the gynodioecious grassland perennial Saxifraga granulata. • METHODS AND RESULTS Based on genomic screening of leaf material of four individuals from four populations, a total of 21 microsatellite primer pairs were designed for S. gran...
متن کاملDevelopment and characterization of polymorphic microsatellite loci for Saxifraga egregia (Saxifragaceae)1
PREMISE OF THE STUDY Saxifraga egregia (Saxifragaceae) is a perennial herb that is endemic to the Qinghai-Tibet Plateau. We developed 12 polymorphic microsatellite loci for S. egregia to investigate its population genetics. METHODS AND RESULTS Forty-eight pairs of microsatellite primers (including 36 monomorphic loci) were isolated and characterized by magnetic bead enrichment. Twelve of thes...
متن کاملPopulation Genetic Differentiation and Taxonomy of Three Closely Related Species of Saxifraga (Saxifragaceae) from Southern Tibet and the Hengduan Mountains
The effects of rapid, recent uplift of the Hengduan Mountains on evolution and diversification of young floristic lineages still remain unclear. Here, we investigate diversification of three closely related Saxifraga species with a distribution restricted to the Hengduan Mountains (HM) and southern Tibet, and comment on their taxonomy based on molecular evidence. Three chloroplast DNA fragments...
