Abstract

Fluorescence in situ hybridization (FISH) is useful in genomic research. We tested FISH in the Pacific oyster, Crassostrea gigas Thunberg, using metaphase chromosomes prepared from early embryos and alI-human telomere and centromere probes. FISH with the all-human telomere probe produced strong hybridization signals at ends of all oyster chromosomes, suggesting that: (1) chromosomes from embryo preparation are suitable for FISH analysis; and (2) the vertebrate telomere sequence, (T2AG3)(n), may be present in telomeres of the Pacific oyster. No interstitial sites were detected for the telomere sequence. FISH with the all-human centromere probe failed to detect any complementary sequences in oyster chromosomes.
