Survey of simple sequence repeats in woodland strawberry (Fragaria vesca)

L. Guan, Huang, J. F., Feng, G. Q., Wang, X. W., Wang, Y., Chen, B. Y., and Qiao, Y. S., Survey of simple sequence repeats in woodland strawberry (Fragaria vesca), vol. 12, pp. 2637-2651, 2013.

The use of simple sequence repeats (SSRs), or microsatellites, as genetic markers has become popular due to their abundance and variation in length among individuals. In this study, we investigated linkage groups (LGs) in the woodland strawberry (Fragaria vesca) and demonstrated variation in the abundances, densities, and relative densities of mononucleotide, dinucleotide, and trinucleotide repeats. Mononucleotide, dinucleotide, and trinucleotide repeats were more common than longer repeats in all LGs examined.

Identification of orchardgrass (Dactylis glomerata L.) cultivars by using simple sequence repeat markers

The accurate identification of orchardgrass (Dactylis glomerata L.) cultivars is necessary to ensure purity for consumers, the effective utilization of cultivars, and to protect the intellectual property for breeders. Therefore, this study aimed to use SSR to construct DNA fingerprinting of orchardgrass cultivars. The genetic diversity of 32 orchardgrass cultivars originated from 21 countries, but grown in China, was assessed using a set of 29 SSR markers distributed across 9 linkage groups of the orchardgrass genome.
