| Abstract | Arachis hypogaea is a widely cultivated crop both as an oilseed and protein source. The genomic analysis of Arachis species hitherto has been limited to the construction of genetic maps; the most comprehensive one contains 370 loci over 2,210 cM in length. However, no attempt has been made to analyze the physical structure of the peanut genome. To investigate the practicality of physical mapping in peanut, we applied a total of 117 oligonucleotide-based probes (“overgos”) derived from genetically mapped RFLP probes onto peanut BAC filters containing 182,784 peanut large-insert DNA clones in a multiplex experimental design; 91.5% of the overgos identified at least one BAC clone. In order to gain insights into the potential value of Arabidopsis genome sequence for studies in divergent species with complex genomes such as peanut, we employed 576 Arabidopsis-derived overgos selected on the basis of maximum homology to orthologous sequences in other plant taxa to screen the peanut BAC library. A total of 353 (61.3%) overgos detected at least one peanut BAC clone. This experiment represents the first steps toward the creation of a physical map in peanut and illustrates the potential value of leveraging information from distantly related species such as Arabidopsis for both practical applications such as comparative map-based cloning and shedding light on evolutionary relationships. We also evaluated the possible correlation between functional categories of Arabidopsis overgos and their success rates in hybridization to the peanut BAC library. |

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.
