Conclusions

The set of microsatellite markers will be suitable for the assessment of genetic diversity in Z. carpinifolia. They will allow for an examination of phylogeographic patterns as well as of population structure and gene flow within this species.

Results

Pyrosequencing of an enriched microsatellite library on the Roche FLX platform using the 454 Titanium kit produced 86,058 sequence reads, most of which contained short tandem repeats. Eighty microsatellite loci identified using the software package QDD version 1 were selected and tested for proper PCR amplification. Of these, 13 allowed proper amplification and were shown to be polymorphic among a sample of 25 Z. carpinifolia specimens from various geographic origins. • Conclusions: The set of microsatellite markers will be suitable for the assessment of genetic diversity in Z. carpinifolia. They will allow for an examination of phylogeographic patterns as well as of population structure and gene flow within this species.
