Microsatellite polymorphism among Chrysanthemum sp. polyploids: the influence of whole genome duplication

Polyploidy is common among flowering plants, including the Asteraceae, a relatively recent angiosperm group. EST-SSRs were used to characterize polymorphism among 29 Chrysanthemum and Ajania spp. accessions of various ploidy levels. Most EST-SSR loci were readily transferable between the species, 29...

EST-SSRs were used to characterize polymorphism among 29 Chrysanthemum and Ajania spp. accessions of various ploidy levels. Most EST-SSR loci were readily transferable between the species, 29 accessions were separated into three groups in terms of the number of fragments.

EST-SSR polymorphism was found and some transcripts containing an SSR were transcribed differently in the de novo autotetraploid C. nankingense and C. lavandulifolium than in their progenitor diploid. EST-SSR could provide a potential molecular basis of adaptation during evolution, while whole genome duplication has a major effect on the mutational dynamics of EST-SSR loci, which could also affect gene regulation.
