RESUMEN
Echinocactus grusonii is common in trade but critically endangered in its natural habitat. With the ultimate aim of developing a certification scheme to aid in the conservation of this species, we have isolated E. grusonii microsatellites from a nonenriched library. Fifty-seven sequences contained a microsatellite array, of which 12 were polymorphic among 30 individuals from a single wild population. All 12 microsatellite primer pairs amplified product in one or more species in a screen of 27 other cactus species.
RESUMEN
Ariocarpus bravoanus is common in trade but critically endangered in its natural habitat. With the ultimate aim of developing a certification scheme to aid in the conservation of this species, we have isolated A. bravoanus microsatellites from a nonenriched library. Fifty-four sequences contained a microsatellite array, of which eight were polymorphic among 23 individuals, 20 from one population and three plants from trade.
