Premise Of The Study:
Microsatellite primers were developed in Pilosocereus machrisii, a columnar cactus with a patchy distribution in eastern tropical South America, to assess its genetic diversity and population structure.
Methods And Results:
Eleven microsatellite markers were developed, of which one was monomorphic among 51 individuals from two populations. The number of alleles per polymorphic locus ranged from two to eight, and the total number of alleles was 57. From the 11 isolated loci, nine were successfully amplified in the other four Pilosocereus species.
Conclusions:
The results showed that these markers will be useful for studies of genetic diversity, patterns of gene flow, and population genetic structure in P. machrisii, as well as across other congeneric species.
