چکیده
PREMISE OF THE STUDY Polymorphic microRNA (miRNA)-based microsatellite markers were developed to investigate the genetic diversity and population structure of Nelumbo nucifera (Nelumbonaceae). METHODS AND RESULTS A total of 485 miRNA-based microsatellites were found from the genomic DNA sequences of N. nucifera. After several rounds of screening, 21 primer pairs flanking di-, tri-, or pentanucleotide repeats were identified that revealed high levels of genetic diversity in four populations with two to five alleles per locus. The observed and expected heterozygosity per locus ranged from 0.000 to 1.000 and from 0.000 to 0.803, respectively. CONCLUSIONS The polymorphic microsatellite markers will be useful for studying the genetic diversity and population structure of N. nucifera.

BACKGROUND Asian lotus (Nelumbo nucifera Gaertn.) is the national flower of India, Vietnam, and one of the top ten traditional Chinese flowers. Although lotus is highly valued for its ornamental, economic and cultural uses, genomic information, particularly the expressed sequence based (genic) markers is limited. High-throughput transcriptome sequencing provides large amounts of transcriptome d...

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...
