| Abstract | Recent discoveries have uncovered considerable genetic diversity among aquatic viruses and raised questions about the variability of this diversity within and between environments. Studies of the temporal and spatial dynamics of aquatic viral assemblages have been hindered by the lack of a common genetic marker among viruses for rapid diversity assessments. Randomly amplified polymorphic DNA (RAPD) PCR bypasses this obstacle by sampling at the genetic level without requiring viral isolation or previous sequence knowledge. In this study, the utility of RAPD-PCR for assessing DNA viral richness within Chesapeake Bay water samples was evaluated. RAPD-PCR using single 10-mer oligonucleotide primers successfully produced amplicons from a variety of viral samples, and banding patterns were highly reproducible, indicating that each band likely represents a single amplicon originating from viral template DNA. In agreement with observations from other community profiling techniques, resulting RAPD-PCR banding patterns revealed more temporal than spatial variability in Chesapeake Bay virioplankton assemblages. High-quality hybridization probes and sequence information were also easily generated from single RAPD-PCR products or whole reactions. Thus, the RAPD-PCR technique appears to be practical and efficient for routine use in high-resolution viral diversity studies by providing assemblage comparisons through fingerprinting, probing, or sequence information. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
