| Abstract | In Allium wakegi, which is an allodiploid species between Allium cepa and Allium fistulosum, each genome can be clearly distinguished using genomic in situ hybridization (GISH). Genomic DNA of A. cepa and A. fistulosum is differentiated both qualitatively and quantitatively. We wanted to isolate nucleotide sequences that give genome-specific signals on A. cepa chromosomes in GISH experiments in A. wakegi. We isolated 23 clones that show GISH-like signal patterns in fluorescence in situ hybridization (FISH) and analyzed their distribution in the A. cepa- and A. fistulosum-derived genomes of A. wakegi. There was considerable variation in the abundance and distribution of these cloned sequences on the chromosomes of the two species. The degree of A. cepa specificity varied among the clones. Twenty-two of the clones showed an even distribution over most chromosome arms with some clustering in the pericentromeric regions, but one clone showed very distinct terminal signals on some chromosomes. Whereas these sequences are not specific for A. cepa, changes in bases in nucleotide sequences and in their amount result in genome-specific characteristics in GISH experiments. |

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.
