New Microsatellite Loci (new + microsatellite_locus)
Selected AbstractsNew polymorphic microsatellite loci for different camel speciesMOLECULAR ECOLOGY RESOURCES, Issue 3 2003D. Evdotchenko Abstract New microsatellite loci were screened and sequenced from the genomic DNA of male Camelus bactrianus. Among 32 loci, 23 were amplified in bactrian and dromedary species, 19 in llama and 20 in alpaca. The different species had similar fragment lengths per locus, with more striking similarities between bactrian and dromedary and between llama and alpaca, respectively. Seven loci had more than 10 alleles each, nine were monomorphic in all species, and one was monomorphic in Old World and polymorphic in New World camels. The results show that the informative microsatellite loci can be widely applied to several species. [source] Characterization and utilization of microsatellite loci in the New World screwworm fly, Cochliomyia hominivoraxMEDICAL AND VETERINARY ENTOMOLOGY, Issue 2009A. M. GRIFFITHS Abstract New World screwworm populations in North and Central America have been the targets of virtually continuous eradication attempts by sterile insect technique (SIT) since the 1950s. Nevertheless, in some areas, such as Jamaica, SIT control programmes have failed. Reasons for the failure of SIT-based control programmes in some locations are unknown, but it has been hypothesized that failure may be related to mating incompatibility between sterile and wild fly populations or to the existence of sexually incompatible cryptic species. This paper outlines the development of a suite of four new microsatellite loci which can be used to study intra-specific relationships between populations of Cochliomyia hominivorax from the Caribbean and South America, which represent those populations involved in, or earmarked for, forthcoming SIT control. Cross-amplification with the secondary screwworm, Cochliomyia macellaria, was also successful with three of the new loci. We present results which suggest that populations from Trinidad and Jamaica form distinct groupings of flies and that C. hominivorax from Trinidad appears particularly distinct. [source] Eleven new microsatellite loci for the tiger rattlesnake (Crotalus tigris)MOLECULAR ECOLOGY RESOURCES, Issue 4 2009A. MUNGUIA-VEGA Abstract Eleven microsatellite loci were isolated from an enriched genomic library from the tiger rattlesnake Crotalus tigris. Average observed heterozygosities in two populations were 0.456 and 0.427, respectively, and mean number of alleles were 7.54 (range 2,14) and 4.72 (range 2,13) respectively. No evidence of linkage disequilibrium was found across pairs of loci. The markers will be used in a long-term study examining the potential effects of urbanization on population dynamics and connectivity of this species in the mountain ranges surrounding Tucson, Arizona. [source] Characterization of 18 new microsatellite loci in Atlantic cod (Gadus morhua L.)MOLECULAR ECOLOGY RESOURCES, Issue 6 2008SIGURLAUG SKIRNISDOTTIR Abstract Eighteen new microsatellite loci consisting of 10 di-, 5 tri-, 2 tetra- and 1 heptanucleotide repeats are introduced for the Atlantic cod (Gadus morhua L.). All loci were co-amplified in two polymerase chain reactions (plus two previously published microsatellites) and all products were typed clearly. The number of alleles per locus ranged from six (PGmo130) to 45 (PGmo76) and the observed heterozygosity ranged from 0.356 (PGmo130) to 0.957 (PGmo95). All loci except one followed Hardy,Weinberg expectations. Genetic linkage disequilibrium analysis between all pairs of loci did not yield any significant values. [source] Development of novel microsatellites from Moniliophthora perniciosa, causal agent of the witches' broom disease of Theobroma cacaoMOLECULAR ECOLOGY RESOURCES, Issue 4 2008JUREMA R. Q. SILVA Abstract Moniliophthora perniciosa is the causal agent of the witches' broom disease of cacao. Based on available genomic sequences, we identified 30 new microsatellite loci, which were analysed using 50 isolates from four populations sampled over a wide geographical area in Brazil, including three populations from the Amazon, the fungal putative centre of diversity, plus one from Bahia. Nine loci were polymorphic, with an average of 2.9 alleles per locus. The level of polymorphism observed was low, but these markers may allow the evaluation of pathogen diversity and the establishment of molecular standards for isolate fingerprinting to support cacao breeding. [source] Characterization of 13 polymorphic microsatellite loci for two land snail species, Trochulus villosus and T. sericeus (Gastropoda: Pulmonata: Hygromiidae)MOLECULAR ECOLOGY RESOURCES, Issue 3 2008A. DÉPRAZ Abstract Thirteen new microsatellite loci were isolated and tested on two land snail species, Trochulus villosus and T. sericeus (Pulmonata: Hygromiidae), resulting in a set of eight polymorphic markers for each species. The expected heterozygosity was high for all loci and species (between 0.616 and 0.944). Such levels of variability will allow detailed insights into the population genetic structure of some Trochulus species. [source] Isolation and characterization of 102 new microsatellite loci in Murray cod, Maccullochella peelii peelii (Percichthyidae), and assessment of cross-amplification in 13 Australian native and six introduced freshwater speciesMOLECULAR ECOLOGY RESOURCES, Issue 6 2007MEAGHAN ROURKE Abstract We have isolated 102 polymorphic microsatellite loci from an enriched Murray cod DNA library and also assessed their amplification success in 13 native and six introduced freshwater fish species. The loci will serve the dual purpose of assessing wild population genetic structure for future conservation efforts, and for identifying markers for key quantitative trait loci important for aquaculture. [source] Characterization of 12 new microsatellite loci in Aenictus and Neivamyrmex army antsMOLECULAR ECOLOGY RESOURCES, Issue 4 2007DANIEL J. C. KRONAUER Abstract Here we describe 12 polymorphic microsatellite loci that were cloned and characterized for three species of army ants: the North American Neivamyrmex nigrescens, and the Asian Aenictus laeviceps and Aenictus dentatus. Observed and expected heterozygosities ranged from 0.37 to 0.97 (mean 0.70), and from 0.48 to 0.95 (mean 0.72), respectively. We observed 2,30 (mean 12) alleles per locus. These new genetic markers will be useful for studies of overall population structure and the complex pedigrees in colonies of army ants. [source] Development of six microsatellite loci for black mangrove (Avicennia germinans)MOLECULAR ECOLOGY RESOURCES, Issue 3 2006IVANIA CERÓN-SOUZA Abstract We developed six new microsatellite loci for the black mangrove (Avicennia germinans), an important member of wetland communities worldwide. Loci showed moderate to high polymorphism and a survey of four locations [Puerto Rico (Jobos Bay and Luquillo), Mexico, French Guyana] revealed clear regional (and local) population structure. All populations were genetically distinct and the two continental populations showed much higher diversity than the two insular Puerto Rican locations. These loci complement those recently published by Nettel et al. (2005) and promise to be valuable for characterizing local and regional population dynamics in the black mangrove. [source] Twenty-seven new microsatellites for the migratory Asian catfish family PangasiidaeMOLECULAR ECOLOGY RESOURCES, Issue 1 2002Zeb S. Hogan Abstract In this paper, we describe primers for 27 new microsatellite loci tested on five species of migratory Asian catfish: Pangasius krempfi, P. bocourti, P. conchophilus, P. pleurotaenia, and Helicophagus waandersii. These primers were developed from a (GATA)n library created from the pooled DNA of three species of pangasiid catfish. All 27 loci are polymorphic in at least one species. Fifteen loci are polymorphic in at least three species. The primers described in this paper are thus shown to be useful in several species within the catfish family Pangasiidae, and may prove useful in additional species in future tests. [source] Twenty-eight new microsatellite loci in chicken and their cross-species amplification in Japanese quail and helmeted guinea fowlANIMAL SCIENCE JOURNAL, Issue 4 2003Boniface Baboreka KAYANG ABSTRACT Twenty-eight original chicken microsatellite markers were isolated and characterized to determine their utility as cross-reactive markers for comparative genetic mapping in the order Galliformes. Primer pairs were typed in 12 unrelated chickens and also tested on Japanese quail and helmeted guinea fowl deoxyribonucleic acid (DNA). Polymorphism was observed in 23 (82.1%) of the markers and the average number of alleles per locus was 2.9 while the mean heterozygosity was 0.19. Eleven (39.3%) of the chicken markers cross-reacted with Japanese quail DNA and 2 (7.1%) with helmeted guinea fowl DNA. The cross-reactive markers described would serve as useful resources for comparative genetic mapping in poultry species belonging to the order Galliformes. [source] | ||||||||||
