| x-cells in pseudotumors of yellowfin goby acanthogobius flavimanus: a protistan organism distinct from that in flathead flounder hippoglossoides dubius. | yellowfin goby acanthogobius flavimanus affected with x-cell pseudotumors were sampled from a river estuary in tokyo bay, japan. we amplified the gene for small subunit ribosomal rna (18s rrna) of x-cells of the goby with pcr using universal primers. the gene that we obtained (ddbj accession no. ab451874) showed 91% sequence identity to that of the x-cells of the flathead flounder hippoglossoides dubius. with in situ hybridization, the probes specific for the gene that we obtained hybridized wit ... | 2009 | 19593933 |
