Development and Application of Quantitative-PCR Tools for Subgroups of the <i>Roseobacter</i> Clade

Abstract

Specific SYBR green-based quantitative-PCR assays targeting conserved regions in the 16S-23S rRNA internal transcribed spacer regions were developed for five subgroups of the environmentally abundant and biogeochemically active Roseobacter clade of marine bacteria. The assays were applied to field samples demonstrating their utility in investigations of abundant Roseobacter group phylotypes in the environment.
