| Abstract | Genomic Representational Difference Analysis (gRDA) is a subtractive DNA method to clone the differences between two related genomes, called tester and driver. We have evaluated this method to obtain polymorphic DNA markers for pedigree dogs. Amplified size-selected genomic restriction fragments (amplicons) of two dog littermates were repeatedly hybridized to each other in order to remove (subtract) those restriction fragments common to both sibs. Already after two rounds of subtractive hybridization, a clear enrichment of presumably tester-specific restriction fragments was observed, which was even more pronounced after the third round of subtraction. A plasmid library of 3000 recombinant clones was constructed of the second round and of the third round difference product. DNA sequence determination of randomly chosen clones of each difference product showed that approximately 1000 unique clones were obtained in the second-round difference product and approximately 500 in the third-round difference product. About half of the clones identified in the second-round difference product were also present in the third-round difference product. Of the second-round difference product, 39 different gRDA fragments could be identified, of which 21 were tester specific. In the third-round difference product, 22 different gRDA fragments were identified, of which 18 were tester specific. There were 13 fragments in common, resulting in a total of 48 different fragments. In order to establish the localization of these markers, we performed mapping using the dog radiation hybrid panel RHDF5000. Of 39 mapped clones, 29 were mapped to 20 existing RH groups, and 10 remained unlinked. It is concluded that gRDA is suitable to generate DNA markers to track disease genes within lines of pedigree dogs. |

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.
