A new set of microsatellite markers for the peach palm (Bactris gasipaes Kunth): characterization and across-taxa utility within the tribe Cocoeae.

A (GA)n microsatellite-enriched library was constructed and a new set of 18 nuclear simple sequence repeat loci was isolated in Bactris gasipaes var. gasipaes. The loci were found to be highly variable in the target species and readily transferable to related Bactris species as well as to the Astrocaryum and Elaeis genera of the same Cocoeae tribe. These microsatellite resources are made available to study the genetic diversity and gene flow within the Bactris complex for a better understanding of the domestication process of the peach palm and for further Cocoeae genetic

Nuclear microsatellite markers for the date palm (Phoenix dactylifera L.): characterization and utility across the genus Phoenix and in other palm genera.

A (GA)n microsatellite-enriched library was constructed and 16 nuclear simple sequence repeat (SSR) loci were characterized in Phoenix dactylifera. Across-taxa amplification and genotyping tests showed the utility of most SSR markers in 11 other Phoenix species and the transferability of some of them in Elaeis guineensis, 11 species of Pritchardia, Pritchardiopsis jeanneneyi and six species of Astrocaryum. The first to be published for P. dactylifera, these new SSR resources are available for cultivar identification, pedigree analysis, germplasm diversity as well as genetic mapping studie
