Evolution of simple sequence repeats
Computers & Chemistry, 1996Simple Sequence Repeats (SSRs) are common and frequently polymorphic in eukaryote DNA. Many are subject to high rates of length mutation in which a gain or loss of one repeat unit is most often observed. Can the observed abundances and their length distributions be explained as the result of an unbiased random walk, starting from some initial repeat ...

Conserved simple sequence repeats for the Limnanthaceae (Brassicales)
Theoretical and Applied Genetics, 2003The Limnanthaceae (Order Brassicales) is a family of 18 taxa of Limnanthes (meadowfoam) native to California, Oregon, and British Columbia. Cultivated meadowfoam ( L. alba Benth.), a recently domesticated plant, has been the focus of research and development as an industrial oilseed for three decades.

Simple sequence repeat map of the sunflower genome
Theoretical and Applied Genetics, 2002Several independent molecular genetic linkage maps of varying density and completeness have been constructed for cultivated sunflower ( Helianthus annuus L.). Because of the dearth of sequence and probe-specific DNA markers in the public domain, the various genetic maps of sunflower have not been integrated and a single reference map has not emerged ...

Repetitive DNA sequences: Some considerations for simple sequence repeats
Computers & Chemistry, 1993Abstract Three topics are treated in this paper: (1) can the polymorphism evident in the length of many simple sequence repeats (SSRs) or microsatellites be explained as a result of unequal mitotic crossing over? We conclude that although this mechanism may be a reasonable explanation for polymorphisms of minisatellite sequences, it is less ...

DNA markers are powerful tools for molecular breeding or checking the genetic homogeneity of F1 hybrid seeds. For the simple and fast approach to detect DNA polymorphisms, simple sequence repeats (SSRs), which are tandem repeats of short sequence motifs (mainly 1–6 bases), are powerful markers because of their codominant mode of inheritance, higher ...

Polymorphism revealed by simple sequence repeats
Trends in Plant Science, 1996Simple sequence repeats (SSRs) are a group of repetitive DNA sequences that represent a significant portion of higher eukaryote genomes. They can serve as highly informative genetic markers, and in conjunction with the use of polymerase chain reaction (PCR) technology enable the detection of length variation.

Some Probabilistic Results on the Nonrandomness of Simple Sequence Repeats in DNA Sequences
Bulletin of Mathematical Biology, 2006Some probabilistic results on simple sequence repeats (SSRs) in DNA sequences are derived and used to quantify the nonrandomness of SSRs as an index of nonrandomness. The applicability of the index of nonrandomness is illustrated using several examples from the literature on selected human diseased genes.

Complex and simple sequences in human repeated DNAs
Chromosoma, 1978Highly repeated human DNA sequences were isolated by isopycnic centrifugation, or were eluted from gels after restriction enzyme cleavage. High molecular weight DNA peaks separable from the bulk of the DNA in a variety of gradients were shown to consist of very simple sequences characteristic of simple satellite DNAs; DNA fingerprint studies indicated ...

Conservation of a dinucleotide simple sequence repeat locus in sharks
Molecular Phylogenetics and Evolution, 2002Recent studies indicate that the flanking region and repeat motif structure of conserved microsatellite loci are useful for phylogenetic inference. Most comparative studies of microsatellite loci involve relatively closely related species, however, primarily because primers developed for one species often amplify only related species.

Simple sequence repeats for germplasm analysis and mapping in maize
Genome, 1996Simple sequence repeats (SSRs) are a relatively new class of DNA markers consisting of short runs of tandemly repeated sequence motifs evenly distributed throughout eukaryotic genomes. Owing to the high rate of variation in the number of repeat units, the polymorphism level shown by SSRs is high.
