| Abstract | In order to construct a simple sequence repeat (SSR)-based genetic linkage map and to promote molecular marker-assisted selection (MAS) in scallop breeding, the methods of Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO)-colony hybridization and expressed sequence tag (EST) database mining were modified and used to develop 95 novel microsatellite markers for Zhikong scallop. The SSR-enriched library constructed by the FIASCO method consisted of 830 clones, and 295 (35.5%) positive clones were identified after colony hybridization. One hundred and fifty clones were randomly sequenced and the results showed all clones contained at least one microsatellite. Of 91 primer pairs designed, 72 were amplified scorable polymerase chain reaction (PCR) products and 70 were polymorphic with the allele number range of 3–16 alleles/locus (average 7.0 alleles/locus). When EST database mining was performed, 66 microsatellites containing ESTs were identified from 3467 sequences deposited in GenBank. Based on cluster analysis of length and GC content of the flanking regions, 47 primer pairs were designed and 23 scorable EST SSRs were obtained. Compared with genomic SSRs developed in this study, EST SSRs showed lower genetic variability with an average of 4.2 alleles/locus. The results in the present study demonstrate that modified FIASCO-colony hybridization is an efficient and low-cost method for the isolation of large numbers of microsatellite markers for scallop species. |

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.
