The outer kinetochore protein scaffold KNL1 is essential for error-free chromosome segregation during mitosis and meiosis. A critical feature of KNL1 is an array of repeats containing MELT-like motifs. When phosphorylated, these motifs form docking sites for the BUB1-BUB3 dimer that regulates chromosome biorientation and the spindle assembly checkpoint. KNL1 homologs are strikingly different in...

Received: 17, March, 2015 Final Accepted: 17, April, 2015 Published Online: 25, April, 2015 Simple sequence repeats (SSRs), also known as microsatellites, are found in DNA sequences and consist of short repeating motifs of 1-6 nucleotides. These repeats are ubiquitous and play an important role in the development of molecular markers. Therefore, the present analysis was conducted to mine SSRs i...

The intergenic spacer (IGS) region of the ribosomal DNA was cloned and sequenced in eight species within the Gibberella fujikuroi species complex with anamorphs in the genus Fusarium, a group that includes the most relevant toxigenic species. DNA sequence analyses revealed two categories of repeated elements: long repeats and short repeats of 125 and 8 bp, respectively. Long repeats were presen...

We analyzed the multilocus short sequence repeats (SSRs) of 211 and 56 isolates of Mycobacterium avium subsp. paratuberculosis and M. avium subsp. avium, respectively. The M. avium subsp. paratuberculosis isolates could be differentiated into 61 genotypes. The M. avium subsp. avium isolates showed limited diversity. These SSRs are stable and suitable for studying the molecular epidemiology of M...

Analysis of short sequence repeats of Mycobacterium avium subsp. paratuberculosis isolated from Crohn's disease patients identified two alleles, both of which clustered with strains derived from animals with Johne's disease. Identification of a limited number of genotypes among human strains implies the existence of human disease-associated genotypes and strain sharing with animals.

A novel dye-free labeling method for a multiplex bioassay was proposed by using short sequence-based barcodes consisting of a reporter base and repeats of two stuffer bases; then, the barcodes were quantitatively decoded by a single pyrosequencing assay without any pre-separation.

The draft genome sequence of Borrelia crocidurae strain 03-02, a blood isolate from a febrile Senegalese patient, comprises a 920,021-bp linear chromosome (27.7% G+C content), 32 tRNAs, 818 open reading frames, and one cluster of regularly interspaced short palindromic repeats. Its genotype differs from that of the Achema reference strain.

The discovery of an anonymous multiallelic locus in 1980 demonstrated for the first time that the human DNA contains hypervariable regions (Wyman & White, 1980). Eight alleles of a polymorphic locus that was not associated with any known gene were identified during the blot hybridization of total human genomic DNA treated with the restrictase EcoRI with a human DNA fragment (16 tbp in length) i...

PsSat5, a cDNA clone from Pisum sativum cv. Alaska, contained a microsatellite consisting of 15 TCA repeats within the 59UTR. This SSR microsatellite was immediately upstream of the presumptive ATG start codon. PCR amplification of genomic DNA from cv. Alaska yielded an identical sequence. This repeat region was analyzed from 10 additional wild and cultivated accessions of Pisum and from four c...
