| Abstract | Genetic diversity of Monopterus albus in a wild population in the Sichuan Basin was investigated by employing mtDNA polymorphisms. The mitochondrial control region was sequenced for a total of 59 individuals collected from four localities. These sequences (553 bp) belonged to 13 haplotypes defined by eight polymorphic sites. The haplotypes were clustered into one lineage, suggesting that Monopterus albus from the Sichuan Basin might originate from a single ancestor in maternal lineages. The genetic differentiation between the population from Zhongxian in Chongqing city and the other three populations, from Mianyang, Longchang, and Ya'an in Sichuan province (F (ST): 0.29167-0.55126), was higher than that among the latter three (F (ST): -0.04196 to 0.05984). Little genetic differentiation was found in the three populations from Sichuan province (Nm: -6.21 to 3.93), and the Zhongxian population also showed lower genetic heterogeneity (P (i): 0.00077 +/- 0.00027; H (d): 0.404 +/- 0.130). The combination of limited variation and weak phylogenetic structure revealed that the Monopterus albus from the Sichuan Basin exhibited lower mtDNA diversity and should probably be treated as a monogroup genetically. |

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.
