Conclusions
The new microsatellite markers will allow the study of genetic diversity and population structure in P. carporrhizans. We propose eight markers to combine in two multiplex reactions for further studies on a larger set of populations.
Results
We cultured P. carporrhizans from ascospores for genomic sequencing with Illumina HiSeq. We successfully developed 11 polymorphic microsatellite markers and associated primer sets and assessed them with 30 individuals from two of the Canary Islands. The average number of alleles per locus was 8.8. Nei's unbiased gene diversity of these loci ranged from 0.53 to 0.91 in the tested populations. Amplification in two closely related species (P. tiliacea, P. cryptotiliacea) yielded only limited success. • Conclusions: The new microsatellite markers will allow the study of genetic diversity and population structure in P. carporrhizans. We propose eight markers to combine in two multiplex reactions for further studies on a larger set of populations.
