Dynamics of Ribulose 15-Bisphosphate Carboxylase/Oxygenase Gene Expression in the Coccolithophorid Coccolithus pelagicus during a Tracer Release Experiment in the Northeast Atlantic

摘要

We report a pronounced diel rhythm in ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) gene expression in a natural population of the coccolithophorid Coccolithus pelagicus sampled during a Lagrangian experiment in the Northeast Atlantic. Our observations show that there is greater heterogeneity in the temporal regulation of RubisCO expression among planktonic chromophytes than has been reported hitherto.
