Parentage test in broad-snouted caimans (Caiman latirostris, Crocodylidae) using microsatellite DNA
Provedor de dados: 74
Autores: Zucoloto,Rodrigo B.; Verdade,Luciano M.; Villela,Priscilla M.S.; Regitano,Luciana C.A.; Coutinho,Luiz L.
In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo, Brazil. Many of the females in the colony were full siblings, which made maternal identification difficult due to genotypic similarity. Even so, the most likely mother could be identified unambiguously among offspring in most of the clutches studied. Two non-parental females displayed maternal behavior which would have misled managers in assigning maternity based on behavior alone. This set of variable loci demonstrates the utility of parentage testing in captive propagation programs.

Parentage testing and effect of misidentification on the estimation of breeding value in Gir cattle
Provedor de dados: 74
Autores: Baron,Erica E.; Martinez,Mário L.; Verneque,Rui S.; Coutinho,Luiz L.
A correct relationship among sires is essential for an efficient breeding program. Microsatellite markers were used in progeny tests, to assess the paternity of seventy-four probable offspring of nine Gir dairy sires. A 36% misidentification rate was observed; however, these errors had minimal effects on the ranking of the nine bulls with regard to their genetic values. The results suggest that paternity tests should be performed in breeding programs, in order to prevent inappropriate paternities from influencing the genetic value of bulls in the future.

In silico identification and characterization of novel microsatellite loci for the Blue-and-yellow Macaw Ara ararauna (Linnaeus, 1758) (Psittaciformes, Psittacidae)
Provedor de dados: 74
Autores: Lima-Rezende,Cássia Alves; Fernandes,Gislaine Aparecida; Silva,Helder Elias da; Dobkowski-Marinho,Sarah; Santos,Victor Fernandes; Rodrigues,Fernando Pacheco; Caparroz,Renato.
Abstract The illegal trade is a major threat to many bird species, and parrots are common victims of this activity. Domestic and international pet markets are interested on different parrot species, such as the Blue-and-yellow Macaw (Ara ararauna). This South American macaw is not globally threatened, but is under protection from over-exploitation. This study aimed to identify and characterize novel microsatellite loci for population and parentage analysis of A. ararauna. Scaffold sequences of Ara macao available in the NCBI database were used for microsatellite searches using MsatCommander software. We tested a total of 28 loci, from which 25 were polymorphic, one was monomorphic, and two did not generated amplification products. For polymorphic loci, the...

Multiplex PCR sets of novel microsatellite loci for the great scallop Pecten maximus and their application in parentage assignment
Provedor de dados: 5
Autores: Morvezen, Romain; Cornette, Florence; Charrier, Gregory; Guinand, Bruno; Lapegue, Sylvie; Boudry, Pierre; Laroche, Jean.
We report the isolation, development and multiplex optimisation of 12 new microsatellite loci for the great scallop, Pecten maximus. Diversity was moderate to high, with number of alleles ranging from 4 to 20 and observed heterozygosity between 0.28 and 0.88. Progeny produced in a commercial hatchery was used to test locus power for parentage assignment. The percentage of offspring that was unambiguously assigned to a unique pair of parents was 97% (software package CERVUS-COLONY). Parentage assignment revealed that 22% of the studied progeny resulted from unplanned crosses. Effective population size of the study progeny was also estimated. Our study illustrates the power of microsatellites for the genetic monitoring of hatchery-produced great scallops.

Genetic evidence supports polygamous mating system in a wild population of Prochilodus lineatus (Characiformes: Prochilodontidae), a Neotropical shoal spawner fish
Provedor de dados: 83
Autores: Ribolli,Josiane; Miño,Carolina Isabel; Scaranto,Bianca Maria Soares; Reynalte-Tataje,David Augusto; Zaniboni Filho,Evoy.
ABSTRACT Behavioral observations made on fish have revealed remarkably diverse reproductive strategies, including polygamy by both sexes. Still, to date, most Neotropical species remain unstudied as to whether the observed reproductive behavior in natural populations correlates with their genetic mating systems. Here, we investigated the genetic mating system of a wild population of Prochilodus lineatus settled in the Middle Uruguay River basin. By using sibship reconstruction and parental inference methods based on microsatellites’ genotypes, we inferred 45 females and 47 males as potential parents of the 87 larvae analyzed. We found evidence supporting polygamous mating in both sexes: while a high percentage of males (44.7%) fertilized the eggs of one...
