چکیده

Genetic variation of microsatellite loci is a widely used method for linkage analysis, individual identification or inter-population studies. Here we analyse a repeated DNA coding sequence and eleven new microsatellites identified within the Trypanosoma (Trypanozoon) brucei genome. Ninety-seven isolates belonging to the five species and subspecies Trypanosoma evansi, T. equiperdum, T. brucei brucei, T. b. rhodesiense and T. b. gambiense were compared regarding the genetic patterns of these markers. The results reveal a great heterogeneity of the genotypes related to the repeated coding sequence and five microsatellites, some of which show a high degree of polymorphism. This allows us to define group-specific genotypes or alleles; in particular, we show that one specific pattern clearly segregates the human pathogen T. b. gambiense group I.

Application of Random Amplified Microsatellite Polymorphism (RAMP) in Prunus Characterization and Mapping

Random amplified microsatellite polymorphism (RAMP) is a PCR-based marker which uses a combination of two classes of markers: Simple sequence repeat (SSR) and Random amplified DNA polymorphism (RAPD) markers. RAMP has been demonstrated to be a potentially valuable molecular marker for the study of genetic relationships in cultivated plant species. The objective of this study was to optimize the...

Use of microsatellite markers for molecular characterization of cumin (Cuminum cyminum L.) ecotypes

In this study, Simple Sequence Repeat markers (SSR) were used to investigate the genetic variation between 49 cumin ecotypes collected from 9 different provinces of Iran. SSR primers Elap1479, Elap040 and Elap1493 showed the highest (89%), while Elap1340 and Elap017 showed the lowest (56%) number of polymorphic bands. Polymorphism information content (PIC) values varied between 0.18 - 0.37. The...
