Microsatellite markers for Amazon pellona Pellona castelnaeana (Clupeiformes: Pristigasteridae)

A. M. Ximenes, Hernández-Ruz, E. J., Machado, V. N., Rodrigues, L. R. R., Ritter, G. C. S., and Farias, I. P., Microsatellite markers for Amazon pellona Pellona castelnaeana (Clupeiformes: Pristigasteridae), vol. 14. pp. 5123-5126, 2015.

The Amazon pellona is one of the few species of Pristigasteridae with recognized commercial value in the Amazon. We isolated 24 and characterized 8 microsatellite loci for this species. The number of alleles ranges from 2-8 per locus. Observed heterozygosities ranged from 0.052-0.823, while expected heterozygosities from 0.052-0.836. These 8 microsatellites are potentially valuable tools for characterizing the levels and distribution of genetic diversity, population structure, and gene flow.

Genetic diversity analysis of the Uruguayan Creole cattle breed using microsatellites and mtDNA markers

E. Armstrong, Iriarte, A., Martínez, A. M., Feijoo, M., Vega-Pla, J. L., Delgado, J. V., and Postiglioni, A., Genetic diversity analysis of the Uruguayan Creole cattle breed using microsatellites and mtDNA markers, vol. 12, pp. 1119-1131, 2013.

The Uruguayan Creole cattle population (N = 600) is located in a native habitat in south-east Uruguay. We analyzed its genetic diversity and compared it to other populations of American Creole cattle. A random sample of 64 animals was genotyped for a set of 17 microsatellite loci, and the D-loop hyper-variable region of mtDNA was sequenced for 28 calves of the same generation. We identified an average of 5.59 alleles per locus, with expected heterozygosities between 0.466 and 0.850 and an expected mean heterozygosity of 0.664.
