| Abstract | c-Jun N-terminal kinase (JNK) is an important member of the mitogen-activated protein kinase superfamily. The allotetraploid crucian carp is a product of distant hybridization of female red crucian carp with male common carp. It is the first natural case of an allotetraploid with stable genetic characters, including fertility of both female and male animals. In this study, 2 jnk1 cDNAs (including jnk1a and jnk1b) have been cloned from the polyploid crucian carp system, consisting of the allotetraploid crucian carp, the triploid crucian carp, and their original parents (red crucian and common carp). We show that jnk1a and jnk1b represent 2 splice forms arising from the jnk1 gene. On the basis of the genetic structure of jnk1a gene in the polyploid crucian carp system, we demonstrated that the allotetraploid crucian carp is phylogenetically closer to its paternal parent (common carp) than to its maternal parent. We further show a similarity between the triploid crucian carp and its original female parent (red crucian carp). Comparisons of genetic structures indicated that the jnk1b genes of allotetraploid and triploid crucian carp are more similar to those of the original paternal parent rather than the original female parent (red crucian carp). RT-PCR analysis indicated that both the jnk1a and jnk1b genes are widely expressed in fish embryos and in the adult organs, displaying distinct features of embryonic-stage and organ specificity in the polyploid crucian carp system. |

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.
