Y. Ben Sassi-Zaidy, Maretto, F., Charfi-Cheikhrouha, F., Mohamed-Brahmi, A., Cassandro, M., Ben Sassi-Zaidy, Y., Maretto, F., Charfi-Cheikhrouha, F., Mohamed-Brahmi, A., and Cassandro, M., Contribution of microsatellites markers in the clarification of the origin, genetic risk factors, and implications for conservation of Tunisian native sheep breeds, vol. 15, p. -, 2016.

The genetic diversity and genetic relationship of the two main groups of African sheep, thin-tailed and fat-tailed sheep, represented by the indigenous Tunisian sheep breeds “Barbarine” (BAR, fat-tailed) and “Queue Fine de l’Ouest” (QFO, thin-tailed) were investigated. The genotypes of 110 animals belonging to these two breeds and their crossbreed (CRO) were assessed using 17 microsatellite markers. The results showed high levels of genetic diversity and a total of 256 alleles were identified in the whole population.

Novel polymorphic microsatellite markers for Bellamya and their application in population genetics of three species

Q. H. Gu, Cheng, Q. Q., Li, X. J., and Zhou, C. J., Novel polymorphic microsatellite markers for Bellamya and their application in population genetics of three species, vol. 14, pp. 15201-15212, 2015.

Bellamya is a widely distributed freshwater snail genus in China; however, its genetic diversity is completely unknown. Sixty-five novel microsatellite loci were isolated and characterized from a microsatellite-enriched library of Bellamya aeruginosa genomic DNA. Most of the 65 loci were successfully amplified. We found high polymorphic information content values for these loci, ranging from 0.235 to 0.892. There were 3 to 12 alleles per locus, and the HE and HO varied from 0.425 to 0.953 and 0.026 to 1.000, respectively.

Isolation and characterization of new microsatellite markers in red tail prawn, Fenneropenaeus penicillatus, an endangered species in China

Y. Yuan, Shangguan, J. B., Li, Z. B., Ning, Y. F., Huang, Y. S., Li, B. B., and Mao, X. Q., Isolation and characterization of new microsatellite markers in red tail prawn, Fenneropenaeus penicillatus, an endangered species in China, vol. 14, pp. 15412-15416, 2015.

Until recently, Fenneropenaeus penicillatus was considered a commercial shrimp species. However, in 2005, it was included on the Red List as an endangered species by the Chinese government. In this study, 19 new microsatellite markers in F. penicillatus were developed and tested in samples of 32 wild individuals from Nanao, China. Twelve loci were polymorphic and 7 were monomorphic. Of the 12 polymorphic loci, the number of alleles per locus ranged from 3 to 6, with an average of 4.42 alleles per locus.

Isolation and characterization of polymorphic microsatellite markers in Bagarius yarrelli using RNA-Seq

M. Du, Liu, Y. H., and Niu, B. Z., Isolation and characterization of polymorphic microsatellite markers in Bagarius yarrelli using RNA-Seq, vol. 14, pp. 16308-16311, 2015.

The yellow sisorid catfish (Bagarius yarrelli) is a vulnerable fish species. In this study, seven polymorphic microsatellite DNA markers for yellow sisorid catfish were described, using RNA-Seq methodology. In B. yarrelli (N = 44) from a Hekou wild population, allelic frequency, and observed and expected heterozygosities per locus varied from two to six, 0.0333 to 0.6793, and 0.0333 to 0.6004, respectively. One locus (Baya153) denoted notable separation from the Hardy-Weinberg equilibrium, after sequential Bonferroni correction (P

Isolation and characterization of microsatellite markers for Osmanthus fragrans (Oleaceae) using 454 sequencing technology

W. J. Yuan, Li, Y., Ma, Y. F., Han, Y. J., and Shang, F. D., Isolation and characterization of microsatellite markers for Osmanthus fragrans (Oleaceae) using 454 sequencing technology, vol. 14, pp. 17154-17158, 2015.

Osmanthus fragrans (Oleaceae) is an evergreen shrub or small tree that grows in south China. In this study, Roche 454 FLX+ sequencing combined with the magnetic bead enrichment method was used to isolate microsatellite markers from the genome of O. fragrans. A total of 1471 microsatellites that contained enough flanking sequences for primer pair design were identified from 89,633 raw sequencing reads. One hundred primer pairs were randomly chosen to test primer amplification efficiency.

Genetic divergence of common bean cultivars

J. S. Veloso, Silva, W., Pinheiro, L. R., Santos, J. Bdos, Fonseca, Jr., N. S., and Euzebio, M. P., Genetic divergence of common bean cultivars, vol. 14, pp. 11281-11291, 2015.

The aim of this study was to evaluate genetic divergence in the ‘Carioca’ (beige with brown stripes) common bean cultivar used by different institutions and in 16 other common bean cultivars used in the Rede Cooperativa de Pesquisa de Feijão (Cooperative Network of Common Bean Research), by using simple sequence repeats associated with agronomic traits that are highly distributed in the common bean genome. We evaluated 22 polymorphic loci using bulks containing DNA from 30 plants. There was genetic divergence among the Carioca cultivar provided by the institutions.

Genetic diversity and genetic structure of consecutive breeding generations of golden mandarin fish (Siniperca scherzeri Steindachner) using microsatellite markers

X. N. Luo, Yang, M., Liang, X. F., Jin, K., Lv, L. Y., Tian, C. X., Yuan, Y. C., and Sun, J., Genetic diversity and genetic structure of consecutive breeding generations of golden mandarin fish (Siniperca scherzeri Steindachner) using microsatellite markers, vol. 14, pp. 11348-11355, 2015.

In this study, 12 polymorphic microsatellites were inves­tigated to determine the genetic diversity and structure of 5 consecu­tive selected populations of golden mandarin fish (Siniperca scherzeri Steindachner). The total numbers of alleles, average heterozyosity, and average polymorphism information content showed that the genetic diversity of these breeding populations was decreasing.
