| Description/Abstract | The minute quantities of Vargula luciferin required to establish long-lasting bioluminescence capability in Puget Sound Porichthys has raised questions concerning the mechanism of luminescence induction. To address these question, a small, known quantity of Vargula luciferin was fed to nonluminescent Puget Sound Porichthys and after monitoring the subsequent light output over a two-year period, it was determined that more light was emitted than could be accounted for by the ingested luciferin. Thus, Porichthys is able to turn over luciferin either by recycling or de novo synthesis. To distinguish between these possibilities, /sup 14/C-labeled luciferin was synthesized and fed to nonluminescent Porichthys. Luciferin recovered from the photophores showed no change in specific activity, demonstrating that incorporation of undiluted Vargula luciferin is sufficient to establish bioluminescence capability in the fish, which is then sustained by recycling of luciferin. Porichthys possesses a specialized mechanism for taking up luciferin from the gut-but shows no apparent specific adaptation for transport of luciferin in the blood. Binding of luciferin to erythrocytes and plasma components greatly retarded the rate of luciferin autoxidation, but appeared to be a nonspecific property of fish blood. |
