Dynamics of a ribulose 1,5-biophosphate carboxylase/oxygenase gene expression in the coccolithophorid Coccolithus pelagicus during a tracer release experiment in the Northeast Atlantic

Article Abstract:

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 is reported. The observations indicate that there is a greater heterogeneity in the temporal regulation of RubisCO expression among planktonic chromophytes.

Molecular and physiological responses of two classes of marine chromophytic phytoplankton (diatoms and prymnesiophytes) during the development of nutrient-stimulated blooms

Article Abstract:

Research has been conducted on the taxon-specific DNA probes that target gene internal region. The development of these probes for marine phytoplankton is discussed.
