چکیده
PREMISE OF THE STUDY To survey population variation and the adaptive evolution of Cephalotaxus fortunei (Cephalotaxaceae), an endemic and endangered conifer in China, microsatellite markers were developed and characterized for this species. METHODS AND RESULTS Based on the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) protocol, 15 microsatellite markers were developed for C. fortunei, 13 of which were polymorphic within a sample of 75 individuals representing five natural populations. The number of alleles per locus ranged from one to seven. The expected and observed heterozygosities were 0.108-0.738 and 0.000-1.000, respectively. Ten polymorphic loci were also successfully amplified in C. oliveri. CONCLUSIONS These polymorphic loci provide a valuable tool for population genetic analysis of C. fortunei, which will contribute to its management and conservation.

Characterization of 15 Polymorphic Microsatellite Loci for Cephalotaxus oliveri (Cephalotaxaceae), a Conifer of Medicinal Importance
Cephalotaxus oliveri is a scarce medicinal conifer endemic to the south central region of China and Vietnam. A small fragmented population presently exists due to anthropogenic disturbance. C. oliveri has been used for its alkaloids harringtonine and homoharringtonine, which are effective against leucocythemia and lymphadenosarcoma. Monoecious plants have been detected in nature, although they ...

Cephalotaxus hainanensis, an endangered plant, is known to contain several metabolites with anti-cancer activity. Despite its clinical impact, the alkaloid metabolism of this species has remained largely uncharacterized. The potential of Cephalotaxus for metabolic engineering of medically interesting compounds has, so far, not been exploited, due to the almost complete lack of molecular informa...

Random amplified microsatellite polymorphism (RAMP) is a PCR-based marker which uses a combination of two classes of markers: Simple sequence repeat (SSR) and Random amplified DNA polymorphism (RAPD) markers. RAMP has been demonstrated to be a potentially valuable molecular marker for the study of genetic relationships in cultivated plant species. The objective of this study was to optimize the...

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...
