Transcriptional response of the model planctomycete Rhodopirellula baltica SH1(T) to changing environmental conditions.

ABSTRACT:

Background

The marine model organism Rhodopirellula baltica SH1(T) was the first Planctomycete to have its genome completely sequenced. The genome analysis predicted a complex lifestyle and a variety of genetic opportunities to adapt to the marine environment. Its adaptation to environmental stressors was studied by transcriptional profiling using a whole genome microarray.

Results

Stress responses to salinity and temperature shifts were monitored in time series experiments. Chemostat cultures grown in mineral medium at 28 degrees C were compared to cultures that were shifted to either elevated (37 degrees C) or reduced (6 degrees C) temperatures as well as high salinity (59.5 per thousand) and observed over 300 min. Heat shock showed the induction of several known chaperone
