Premise of the study: Simple sequence repeat (SSR) markers were developed for Aster savatieri (Asteraceae) and the serpentine variety A. savatieri var. pygmaeus to re-evaluate their taxonomic status.
Methods and Results: Using RNA-Seq data, 22 expressed sequence tag (EST)-SSR markers were developed. Polymorphisms were assessed in A. savatieri and in A. savatieri var. pygmaeus. The average number of alleles ranged from four to 15, and expected heterozygosity ranged from 0.417 to 0.870. Transferability was examined in six representative species of Japanese Aster and in Solidago virgaurea subsp. asiatica var. asiatica, a member of the tribe Astereae (Asteraceae); most of the loci were transferable to these examined species.
Conclusions: These markers will be useful for genetic studies of variation in A. savatieri and other Aster species that occur in Japan.
