Isolation of microsatellite loci from the endangered plant Galium catalinense subspecies acrispum (Rubiaceae)

摘要

Galium catalinense subspecies acrispum (Rubiaceae) is a state-endangered perennial shrub endemic to San Clemente Island. Eight polymorphic microsatellite loci were isolated from G. catalinense ssp. acrispum. These loci show high levels of variability, averaging 6.5 alleles per locus and an expected heterozygosity of 0.550. One locus exhibited significant deviations from Hardy-Weinberg equilibrium (P < 0.01) and one pair of loci exhibited significant linkage disequilibrium.
