An analysis of the Sargasso Sea resource and the consequences for database composition

Michael L Tress, Domenico Cozzetto, Anna Tramontano, Alfonso Valencia
2006 BMC Bioinformatics  
The environmental sequencing of the Sargasso Sea has introduced a huge new resource of genomic information.  ...  The Sargasso Sea sequences seem to introduce a bias that decreases the potential of current methods to propose structure and function for new proteins.  ...  Acknowledgements The authors wish to thank David Juan, Florencio Pazos, Luis Sanchez-Pulido and the referees for their useful critical input.  ...

Estimating the extent of horizontal gene transfer in metagenomic sequences

Javier Tamames, Andrés Moya
2008 BMC Genomics  
The methods are based on phylogenetic and DNA compositional approaches, and have allowed us to assess the extent of possible HGT events in metagenomes for the first time.  ...  Nevertheless, the study of the number of HGT events in metagenomic sequences from different communities shows a consistent trend for both methods: the lower amount is found for the sequences of the Sargasso  ...  Financial support was provided by projects BFU2006-06003 from the Spanish Ministry of Education and Science (MEC) and GV/2007/050 from the Generalitat Valenciana, Spain.  ...

INDUS - a composition-based approach for rapid and accurate taxonomic classification of metagenomic sequences

Monzoorul Mohammed, Tarini Ghosh, Rachamalla Reddy, Chennareddy Venkata Siva Kumar Reddy, Nitin Singh, Sharmila S Mande
2011 BMC Genomics  
Taxonomic classification of metagenomic sequences is the first step in metagenomic analysis. Existing taxonomic classification approaches are of two types, similarity-based and composition-based.  ...  Since, metagenomic projects generate millions of sequences, adopting similarity-based approaches becomes virtually infeasible for research groups having modest computational resources.  ...  Acknowledgements We thank Stephan Schuster and Daniel Huson for allowing us to use MEGAN and MetaSim software for this work. We thank Sudha Chadaram for her help in preparing a web-server for INDUS.  ...
