TI  - Pirellula and OM43 are among the dominant lineages identified in an Oregon coast 
      diatom bloom.

AB  - Although bacterioplankton and phytoplankton are generally perceived as closely 
      linked in marine systems, specific interactions between discrete bacterioplankton 
      and phytoplankton populations are largely unknown. However, measurements of 
      bacterioplankton distributions during phytoplankton blooms may indicate specific 
      microbial lineages that are responding to phytoplankton populations, and 
      potentially controlling them by producing allelopathic compounds. Here we use a 
      comprehensive molecular approach to identify, characterize and quantify 
      bacterioplankton community responses to an Oregon coast diatom bloom. Total DAPI 
      counts increased by nearly sevenfold in bloom samples, reaching 5.7 x 10(9) cells 
      l(-1), and lineage-specific cell counts using fluorescence in situ hybridization 
      (FISH) indicated that Bacteria accounted for approximately 89% of observed 
      increases. Several dominant members of the bacterial community present outside 
      the bloom (SAR11 and SAR86) did not contribute significantly to observed 
      increases in bloom samples. Clone library and FISH data indicated that uncultured 
      planctomycetes most closely related to Pirellula, and members of the OM43 clade 
      of beta proteobacteria, reached 0.5 x 10(8) and 1.2 x 10(8) cells l(-1), 
      respectively, and were among the dominant lineages in bloom samples.
