Polymorphic microsatellite markers in Anthoxanthum (Poaceae) and cross-amplification in the Eurasian complex of the genus1

چکیده
PREMISE OF THE STUDY Nonplastid microsatellite primers were developed for the first time in the Euro-Siberian complex of Anthoxanthum (Poaceae), a genus of temperate grasses in which reticulate evolution is common. METHODS AND RESULTS A microsatellite-enriched genomic DNA library allowed the detection of 500 fragments containing a microsatellite motif. Fifteen primer pairs were selected for an extended primer test. A preliminary analysis was conducted on the Eurasian diploid lineages of Anthoxanthum, with special emphasis on three populations of the Mediterranean A. aristatum-A. ovatum complex. Thirteen out of 15 markers tested were polymorphic in the complex, with successful cross-amplification in A. odoratum (93% polymorphic loci), A. amarum (73% polymorphic), A. alpinum (73% polymorphic), and A. maderense (60% polymorphic). CONCLUSIONS These microsatellite markers will enable the analysis of evolution and phylogeography in diploid and polyploid lineages of this important genus.

Common kilka Clupeonella cultriventris (Nordmann, 1840) is a brackish water and small pelagic fish species and is one of the most abundant fishes that live gregariously in the Caspian Sea. A total of 60 specimens of adult common kilka were sampled from two seasons. Fifteen pairs of microsatellites previously developed for A.sapidissima, C. pallasi, C.harengus, and S. pilchardus were tested for ...

Microsatellite enriched library of Hyriopsis cumingii was constructed according to the strong affinity between biotin and streptavidin. One hundred clones with foreign inserts were sequenced and 65 clones were screened for usable microsatellites, of which 36 were deemed unique, of sufficient length (more than 8 repeats) and possessed adequate flanking regions for primer designment. Among 36 pri...

Microsatellites or simple sequence repeats (SSRs) are very effective molecular markers in population genetics, genome mapping, taxonomic study and other large-scale studies. Variation in number of tandem repeats within microsatellite refers to simple sequence length polymorphism (SSLP); but there are a few studies that are showed SSRs replication slippage may be occurred during in vitro amplifi...
