| Abstract | DNA sequences of an 847 bp fragment of mitochondrial cytochrome oxidase subunit I (COI) gene and a 514 bp fragment of 16s rRNA gene were determined to examine the phylogenetic relationships of 12 Penaeoidea shrimp species (Penaeus chinensis, Penaeus japonicus, Penaeus penicillatus, Penaeus vannamei, Penaeus canaliculatus, Trachypenaeus curvirostris, Metapenaeus affinis, Metapenaeus ensis, Metapenaeopsis barbata, Parapenaeus fissuroides, Parapenaeopsis hardiwickii, Solenocera crassicornis). Both fragments of the swimming crab Portunus trituberculaus chosen as the outgroup were also sequenced. Intraspecific sequence divergence of 0.24–1.2% in the COI gene was found in 5 species, while no intraspecific variation was observed in the 16s rRNA gene. Three phylogenetic trees based on the 1361 bp combined sequences of COI and 16s rRNA were concordant in indicating the following suggestions: (1) phylogenetic relationship of the 11 Penaeidae species based on our result support the opinion of Burkenroad (Burkenroad, M. D. (1983). Crustacean Issues 3:279–290) on the basis of morphological features; (2) it seems more reasonable to class Solenocera crassicorni in the family Penaeidae; (3) the fragment of the COI gene chosen here appears to be a good marker for speciation studies and population analysis in Crustaceans, while the 16s rRNA gene fragment here seems suitable for examining phylogenetic relationships at the species or genus levels in Crustaceans. Our time estimates suggest that Penaeus and Metapenaeus might have separated about 6.38 × 106–7.98 × 106 years BP in the post-Miocene, and the species separation within Metapenaeus and Penaeus might occur 0.08 × 106–0.4 × 106 years BP in the late Pleistocene. |

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.
