Premise Of The Study:
A set of novel chloroplast microsatellite markers (cpSSRs) was developed for the bioenergy crop Miscanthus, and their utility in cross-species amplification was evaluated.
Methods And Results:
Twenty-eight novel primers flanking cpSSR loci were designed from a complete chloroplast genome sequence of Saccharum officinarum, a species closely related to Miscanthus. These primers were then tested on eight Miscanthus species, among which 16 cpSSR loci were found to be polymorphic. The number of alleles per polymorphic locus ranged from two to seven, with an average 3.94 alleles.
Conclusions:
These cpSSR markers can be applied to all Miscanthus species and will be useful for studying Miscanthus population structure, diversity, and phylogeography.
