Metagenomes collected at different depths and times in the Oxygen Minimum Zone off the coasts of Chile.
The oceanic oxygen minimum zone samples were collected in June 2008 off Iquique, Chile, (20.104o S and 70.404o W). Oxygen minimum zone viral metagenomes were constructed by filtering 40 l of water collected using a CTD rosette lowered to a sampling depth of 90 and 200 m (named OxMinZoneVir200806-90 and OxMinZoneVir200806-200 respectively). Samples were concentrated through a 100 kDa tangential flow filter to retain viral particles. The concentrate was passed through a 0.45 mkm sterivex filter to remove larger cells and treated with chloroform. The viruses were purified using cesium chloride (CsCl) step gradients to remove free DNA and any cellular material. More...

The viruses were purified using cesium chloride (CsCl) step gradients to remove free DNA and any cellular material. Viral samples were visually checked for microbial contamination using epifluorescence microscopy. Viral DNA was extracted using CTAB/phenol:chloroform extractions and amplified using Genomiphi reactions. These reactions were pooled and purified using silica columns (Qiagen Inc, Valencia, CA). The DNA was precipitated with ethanol and re-suspended in water at a concentration of approximately 300 ng mkl-1. Sequencing was performed using pyrosequencing on Roche Applied Sciences/454 Life Sciences GS-FLX platforms with a practical limit of 250 bp. Duplicate sequences were removed from the obtained dataset. Less...
