Isolation and characterization of microsatellite loci in the threatened brook lamprey <i>Lethenteron</i> sp. N

Abstract

Abstract A microsatellite‐enriched genomic library was obtained for the threatened brook lamprey, Lethenteron sp. N, and from it 16 dinucleotide markers were successfully isolated and characterized. These markers were found to have between 1 and 6 alleles with heterozygosity ranging from zero to 0.79. Cross‐species amplification was successful, with eight loci amplifying products in the counterpart cryptic species, Lethenteron sp. S, as well as 15 loci in Lethenteron japonicum . One out of 10 primer pairs previously reported also amplified products in all the three species.
