Premise Of The Study: Microsatellite markers were developed for species in the genus Selliera (Goodeniaceae) for future investigations of population genetic structure and interspecific hybridization within the genus.
Methods And Results: Using 454 pyrosequencing, 15 new markers were developed from microsatellite loci isolated from S. radicans. Primers for the new markers amplify di- and trinucleotide repeat loci from the three Selliera species screened. Ten of the new markers are polymorphic in S. radicans and six of those 10 loci were found to be polymorphic within each congener. For the focal species, S. radicans, the average number of alleles per locus is 3.7 (SE = 0.60) and the average observed and expected heterozygosities are 0.23 (SE = 0.07) and 0.47 (SE = 0.08), respectively.
Conclusions: The new markers provide an important resource for future investigations in the genus Selliera for both population genetics and research into hybridization between species.

To clarify the genetic diversity and structure of the nucleus population of F1-generation , this study utilized 15 pairs of highly polymorphic microsatellite primers to analyze the simple sequence repeat (SSR) markers and genetic diversity in 15 full-sib families of . . A total of 112 alleles () and 60.

Microsatellites are present in mitochondria, chloroplast, and nuclear DNA, but nuclear microsatellites are more useful genetic tools than those in plastids or mitochondria. Plastid and mitochondrial microsatellites have been identified in the model plant (liverwort), but no laboratory has published information on nuclear microsatellite loci. The aim of this study was to detect novel nuclear markers in the most commonly employed liverwort species, design PCR primers that would allow amplification, and characterize the subsequently generated loci.

Microsatellite instability (MSI) detection using tumor tissue is a well-established prognostic and predictive biomarker for certain types of cancers. However, tumor tissue samples are less convenient to obtain than blood plasma samples. The main challenge facing next-generation sequencing-based MSI detection in blood plasma samples is the ultralow signal/noise ratio in plasma cell-free DNA (cfDNA).

Beluga whales () inhabit the circumpolar Arctic and form discrete summer aggregations. Previous genetic studies using mitochondrial and microsatellite loci have delineated distinct populations associated to summer aggregations but the extent of dispersal and interbreeding among these populations remains largely unknown.

Background: Pueraria is an edible and medicinal raw material, which is of great value to the pharmaceutical and food industries. Nonetheless, due to morphological diversity and complex domestication history, the classification of Pueraria plants is ambiguous. As the varieties on the market are mixed, the species are difficult to distinguish, and their morphological characteristics are similar to the physical and chemical properties.
