Tri- and tetranucleotide microsatellites in dhufish Glaucosoma hebracium (Perciformes).

Distribution of Polymorphic and Non-Polymorphic Microsatellite Repeats in Xenopus tropicalis

The results of our bioinformatics analysis have found over 91,000 di-, tri-, and tetranucleotide microsatellites in our survey of 25% of the X. tropicalis genome, suggesting there may be over 360,000 within the entire genome. Within the X. tropicalis genome, dinucleotide (78.7%) microsatellites vastly out numbered tri- and tetranucleotide microsatellites. Similarly, AT-rich repeats are overwhel...

Increased yield of tri- and tetranucleotide heterospecific microsatellites from unenriched small-insert libraries.

Estimating Y chromosome specific microsatellite mutation frequencies using deep rooting pedigrees.

Recently, a set of highly polymorphic chromosome Y specific microsatellites became available for forensic, population genetic and evolutionary studies. However, the lack of a mutation frequency estimate for these loci prevents a reliable application. We therefore used seven chromosome Y tetranucleotide repeat loci to screen 42 males who are descendants from 12 'founding fathers' by a total numb...

Characterization of di-, tri-, and tetranucleotide microsatellite markers with perfect repeats for Trypanosoma brucei and related species.

Trypanosoma brucei, unicellular parasites causing human sleeping sickness and animal nagana, have a great impact on the socio-economic environment of sub-Saharan Africa. The dynamics of the parasite are still poorly understood. We have characterized 14 polymorphic di-, tri-, and tetranucleotide microsatellite loci with perfect repeats (only one motif) exhibiting between 5 and 16 alleles in T. b...

Characterization of Tri- and Tetranucleotide Microsatellites in the Black Tiger Prawn, Penaeus monodon

In order to characterize triand tetranucleotide microsatellites in the black tiger prawn, Penaeus monodon, a genomic library of P. monodon was screened with the repeats (GAA)n, (GATA)n, (GGAT)n, (GGAA)n and (CACC)n. In the 79 positive clones isolated, the repeats (GATA)n was found at the highest frequency, followed by the (GAA)n while the other sequence types were rare or not found. Sequencing ...
