| Abstract | Interferons (IFNs) are cytokines that induce an antiviral state in vertebrate cells. The Atlantic salmon (Salmo salar) IFN gene (SasaIFN-alpha1) was introduced in potato and rice plants by Agrobacterium-mediated transformation to produce a biologically active fish IFN in these plants. The transgenes and their transcripts were detected by PCR and Northern blot analysis. Western blot analysis showed the existence of SasaIFN-alpha1in transgenic plants. The antiviral activity of the SasaIFN-alpha1 protein expressed in these plants was determined by the survival rates of pre-treated cultured fish cells against pancreatic necrosis virus infection. The survival rate of cells pre-treated with transgenic samples was up to 95% but was reduced to 30-47% when cells were pre-treated with non-transgenic samples. These results demonstrated an antiviral effect of the SasaIFN-alpha1 protein derived from transgenic plants. Plant-derived IFNs may be suitable as components of functional feeds because such IFNs are free of animal pathogens and can be produced at a lower cost compared with those from transgenic mammalian and bacterial cells. This is the first study describing the production of a biologically active fish IFN using transgenic plants. |

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.
