Geochemical rate-RNA integration study: ribulose-1,5-bisphosphate carboxylase/oxygenase gene transcription and photosynthetic capacity of planktonic photoautotrophs

Article Abstract:

The relationship between the photosynthetic capacity of autotrophic plankton and the transcriptional activity of variants of the large subunit gene (rbcL) for ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) is reported. The results suggest that diatoms are major contributors to carbon fixation at LEO 15 at the time of sampling and that photosynthetic carbon fixation was partially controlled by transcriptional regulation of the RubisCO gene.

Complete genome sequence of phisHSIC, a pseudotemperate marine phage of listonella pelagia

Article Abstract:

The genome for the marine pseudotemperate member of the siphoviridae phisHSIC was sequenced using a combination of linker amplification library construction, restriction digest library construction, and primer walking. phisHSIC enters into a pseudolysogenic relationship with its host, Listonella pelagia, characterized by sigmoidal growth curves producing >10(super 9) cells/ml and >10(super 11) phage/ml.

Detection and quantification of the red tide dinoflagellate Karenia brevis by real-time nucleic acid sequence-based amplification

Article Abstract:

A novel molecular assay has been developed, using nucleic acid sequence-base amplification (NASBA), to detect and quantify Karenia brevis organisms via the ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO) large-subunit gene (rbcL). NASBA is used to detect and quantify K. brevis in the marine environment.
