| Abstract | INTRODUCTIONThe best tissue sections are obtained from plastic-embedded material. These sections are more difficult and more expensive to prepare than those from Paraplast-embedded material, but the superior results make the additional effort worthwhile. The procedure starts with a fixative cocktail that includes a quickly penetrating fixative, such as paraformaldehyde, and one that is good for preserving fine structure, such as glutaraldehyde. Next, the samples are stained to facilitate manipulation of embedded tissue. After dehydration and staining, the tissue is infiltrated with resin. Finally, the embedded tissue is mounted and sectioned. The following protocol can be used on roots, leaves, shoot apices, and flowers, but the duration of infiltration must be adjusted for the various tissue types. Roots can be processed within 2 d, whereas leaves and flowers require up to 2 wk infiltration. Because Arabidopsis seedlings are small, whole seedlings (1-2 weeks old) can be fixed (including the root system) without dissection. Similarly, entire inflorescences, including those that have just opened, can be processed. Before embedding, the fixed material should be dissected to isolate organs of interest, such as individual flowers, to allow better orientation. Leaves from plants older than 2 wk should be cut into 1-cm(2) pieces and fixed individually. |

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.
