| Abstract | We isolated novel dinucleotide, trinucleotide, and tetranucleotide microsatellites from the genome of Asian sea bass (Lates calcarifer). Two genomic DNA libraries were established, one was enriched for (CA)n repeats, while the other for (GATA)n, (GACA)n, and (AAC)n repeats. Sixty clones containing an insert between 250 and 1000 bp in size were sequenced from each library; altogether 50 (43%) of them contained microsatellites. Forty microsatellites were characterized in 16 unrelated Asian sea bass individuals. Twenty-eight of them (70%) showed specific amplification and polymorphism. The allele number per loci varied between 2 and 20 with an average of 5.3, while expected heterozygosity ranged from 0.31 to 0.95 with an average of 0.64. At some loci allele sizes spread over a wide range (>100 bp). No significant correlation (r = 0.23, df = 31, P > 0.05) was found between the repeat number and the number of alleles. A whole broodstock containing 170 individuals was analyzed by using 8 selected polymorphic microsatellites. The average number of alleles per locus was 11.8 (range, 4–21). The expected heterozygosity ranged from 0.57 to 0.90 with an average of 0.75, while the fixation index was 0.02. Genetic similarity between individuals ranged from 0 to 0.72. Comparison of allele frequencies between the broodstock and the 24 nonrelated individuals revealed some unique alleles. |

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.
