Cross-species transferability of microsatellite markers in the genus Lippia.

The cross-species transferability of 20 microsatellite markers was tested in the genus Lippia. Eleven markers were polymorphic after screening 19 accessions of Lippia sidoides and Lippia gracilis maintained in the Active Germplasm Bank (AGB) from Universidade Federal de Sergipe. Additionally, 40 accessions of Lippia spp were collected in Sergipe to increase the germplasm bank. A total of 23, 22, and 36 alleles were identified, with an average of 2.3, 2.2, and 3.27 alleles per locus, respectively, for each group. The markers that were used were efficient tools to access genetic diversity in the germplasm bank and will be useful for further research aiming at the conservation and management of these important aromatic species.

Development and characterization of microsatellite markers for Lychnophora pinaster: a study for the conservation of a native medicinal plant.

Lychnophora pinaster Mart. (Asteraceae) is a Brazilian medicinal plant, extensively employed in popular medicine as an anti-inflammatory, analgesic and healing agent. Thirteen polymorphic microsatellite markers were developed and optimized for L. pinaster from an enriched genomic library. The markers were used to analyse 37 plants from two native populations, generating an average number of 6.6 alleles per polymorphic locus. These loci are important tools for future studies of population genetics.
