The sturgeon microsatellite LS-39 was amplified across 10 different species
of Acipenserinae and exhibited the potential to identify the black caviar
producer Acipenser stellatus on a genomic DNA level. This was because of a
fixed allele of 111 bp, which was absent in the other species which were in
vestigated. Concerning the source of sturgeon species, LS-39 is the first n
uclear marker described to examine black caviar. Furthermore, new light is
shed on the controversial ploidy state of sturgeons. The present authors fi
ndings at this microsatellite locus support the hypothesis that extant simi
lar to 120 chromosomal species are modern diploids, whereas sturgeons with
similar to 240 chromosomes should be considered as modern tetraploids.
