Microsatellite primers in the white proteas (Protea section Exsertae, Proteaceae), a rapidly radiating lineage

Am J Bot. 2010 Jan;97(1):e1-3. doi: 10.3732/ajb.0900326. Epub 2009 Dec 11.

Abstract

Premise of the study: Microsatellite primers were developed in the South African sclerophyllous shrub Protea punctata to investigate the degree of population differentiation within and between P. punctata and closely related species. •

Methods and results: 10 primer pairs were identified from three individuals of Protea punctata. The primers amplified di- and tri-nucleotide repeats. Across all P. punctata samples, the loci have 8-49 alleles. All primers also amplified in Protea section Exsertae (P. aurea, P. aurea subsp. potbergensis, P. mundii, P. venusta, P. lacticolor, and P. subvestita). The loci had 14-69 alleles across the subgenus. •

Conclusions: These results show the broad utility of microsatellite loci for future studies of population genetics in the white proteas and their potential utility across the entire genus.
