| Abstract | Amplified fragment length polymorphism (AFLP) markers were employed to deteet genetic variation among species of Papever (section Oxytona) and assess genetic fidelity between in vitro cell lines of Papaver bracteatum and mature plants derived from the propagation of their callus cultures. Regenerated plants exhibited morphological and phytochemical characteristics dissimilar to those of their source material. Thebaine, the dominant alkaloid produced by Papaver bracteatum, was not detected in capsules from mature regenerated accessions, indicating that there may have been a loss of genetic uniformity. Instead, the dominant alkaloid produced by the regenerated plant was shown to be isothebaine (by TLC and GC/MS), a metabolic characteristic of P. pseudo-orientale. A Neighbor-Joining tree constructed from AFLP fingerprints distinetly separates the three species of Oxytona while firmly grouping the in vitro-cultured plants with P. pseudo-orientale. Additionally phytochemical data and chromosome counts indicate that the seed used to initiate cultures was of hybrid origin and ihat the loss in genetic uniformity was not due to somaclonal variation occurring during the in vitro culture process. AFLP fingerprinting was therefore able to differentiate Oxytona species and invesgigate allopolyploidy in closely related papaver 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.
