| Abstract | An efficient and reliable transformation system for a very important medicinal plant Papaver bracteatum was developed through optimization of several factors that affect the rate of effective A. rhizogenes-mediated transformation and growth rate of hairy root. Five bacterial strains, A4, ATCC15834, LBA9402, MSU440 and A13, and three explants types, hypocotyls, leaves and excised shoots were examined. The highest frequency of transformation was achieved using LBA9402 strain in the excised shoots. Several inoculation and co-cultivation media and different concentration of arginine were evaluated using LBA9402 strain and the excised shoots as explant. Interestingly, a drastic increase in the frequency of transformation (47.3 %) was observed when Murashige and Skoog medium containing 1 mM arginine and lacking NH$_{4}$NO$_{3}$ KH$_{2}$PO$_{4}$, KNO$_{3}$ and CaCl$_{2}$ was used. The effect of sucrose concentration and the ratio of NH$_{4}$ $^{+}$: NO$_{3}$ $^{−}$ on hairy root biomass was examined. Maximum biomass was obtained in 30 g/l sucrose and 20:10 mM ratio of NH$_{4}$ $^{+}$ to NO$_{3}$ $^{−}$ on MS medium. Transgenic hairy root lines were confirmed by polymerase chain reaction (PCR) and Southern hybridization. |

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.
