Isolation and characterisation of microsatellite loci in Calystegia soldanella (Convolvulaceae), an endangered coastal plant isolated in Lake Biwa, Japan
Eight microsatellite loci of Calystegia soldanella useful for comparisons of the genetic structure of isolated populations in the ancient Lake Biwa and coastal populations in Japan were isolated and characterised. The number of alleles ranged from 2 to 5. The expected (H E) and observed (H O) heterozygosities were 0.097–0.583 and 0.000–0.380, respectively, from 100 individuals from Lake Biwa and coastal populations. Seven of the eight loci exhibited significantly fewer heterozygotes than expected based on the Hardy–Weinberg equilibrium (P < 0.05). These primers amplifying microsatellites in C. soldanella may provide a population genetics tool useful in the establishment of a conservation strategy.
