| Abstract | The chromosomal and genomic organization of 5 cloned AFLP fragments in asparagus (Asparagus officinalis L.) were investigated. Two of the 5 AFLP loci were sex-linked. The fragments, amplified with EcoRI/MseI primers, ranged from 107 to 267 bp and were AT-rich. Southern hybridization gave interspersed, middle repetitive to high copy sequence signals. Fluorescence in-situ hybridization (FISH) exhibited hybridization signals on all chromosomes with dispersed distribution pattern and varying signal intensities. Repetitive signals in the form of clusters were observed on all chromosomes. In addition, the 5S rRNA gene was physically mapped on one pair of chromosomes and the 18S-5.8S-25S rRNA genes on three pairs. The results of the FISH and Southern analyses showed that the AFLP marker technology relies on repetitive sequences. Since repetitive DNA sequences represent a fraction of the plant genome undergoing rapid changes during the course of evolution, the question of whether such molecular markers originating from repetitive DNA sequences remain stable is discussed. |

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.
