| Abstract | An insertion element [transferred DNA (T-DNA)], transferred by soil agrobacteria into the nuclear genome of plants, was used for induction of gene fusions in Arabidopsis thaliana, Nicotiana tabacum, and Nicotiana plumbaginifolia. A promoterless aph(3')II (aminoglycoside phosphotransferase II) reporter gene was linked to the right end of the T-DNA and transformed into plants along with a plasmid replicon and a selectable hygromycin-resistance gene. Transcriptional and translational reporter gene fusions were identified by screening for APH(3')II enzyme activity in diverse tissues of transgenic plants. The frequency of gene fusions, estimated by determination of the copy number of T-DNA insertions, showed that on average 30% of T-DNA inserts induced gene fusions in Arabidopsis and Nicotiana. Gene fusions were rescued from plants by transformation of the T-DNA-linked plasmid and flanking plant DNA into Escherichia coli. By dissection of gene fusions and construction of chimeric genes, callus- and root-specific promoters were identified that showed an altered tissue specificity in the presence of a 3'-downstream-located 35S promoter. Transcript mapping of a gene fusion and expression of a non-frame transcriptional fusion of bacterial luciferase luxA and luxB genes demonstrated that dicistronic transcripts are translated in tobacco. |

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.
