Abstract
Scutellaria austrotaiwanensis is a new species first described in 1997. It is a rare and endemic species in southern Taiwan. In this study, 16 polymorphic microsatellite loci were isolated from Scutellaria austrotaiwanensis using a magnetic bead enrichment method. Several genetic indices, including observed heterozygosity (Ho), expected heterozygosity (He), number of effective alleles (Ne), and polymorphism information content (PIC), were calculated. Deviation of heterozygosity was detected by the fixation index (Fis) and Hardy–Weinberg equilibrium was tested by possibilities (P HWE) using a chi-squared test. Allele numbers ranged from 4 to 8, with observed heterozygosity ranging from 0.611 to 1.000. Five microsatellite markers showed deficient heterozygosity by Fis > 0. No loci exhibited a departure from Hardy–Weinberg equilibrium, possibly due to a stable population. No loci pairs revealed significant linkage disequilibrium. The microsatellite markers reported here should be useful to evaluate the population structure of S. austrotaiwanensis for conservation efforts.
