| Abstract | Hypocotyls and cotyledons of three ramie (Boehmeria nivea Gaud.) cultivars (Zhongzhu No.1, Zhongsizhu No.1 and NC01), important plants for textile fiber, were pre-cultured on callus-inducing medium for 1 day before co-cultivation for 2 days with Agrobacterium tumefaciens strain LBA4404 harboring the plasmid pGBI4ABC carrying two insect resistance (CryIA and CpTI), gus, and neomycin phosphotransferase (npt II) genes. Calli were induced from both hypocotyl and cotyledon explants grown on a kanamycin selection medium. Regenerated shoots were obtained after two cycles of culture and transferred to rooting medium. Kanamycin-resistant plantlets were rooted in 2 weeks, and then transplanted to soil. Transgenic plants were subsequently confirmed by polymerase chain reaction, Southern blot hybridization, and GUS assays. More than 100 transgenic plants carrying insect-resistance genes were produced. A transformation frequency of 8.8 to 10.3% was obtained using hypocotyls as explants, which was higher than all previously reported transformation frequencies. The whole protocol, from transformation recovery of plants grown in soil, was completed within 2–4 months. Therefore, a simple, efficient, and robust Agrobacterium tumefaciens -mediated transformation system for ramie has been developed. |

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.
