| Abstract | In vitro cultivation systems of arbuscular mycorrhizal fungi are useful tools to study the interaction between plants and their fungal symbiont, and also to develop new biotechnologies. Plantlets of the latex-producing species Hevea brasiliensis clone PB 260 were grown in a dense extraradical mycelium network of the arbuscular mycorrhizal fungus Rhizophagus irregularis MUCL 41833 developed from a mycelium donor plant (Medicago truncatula A17). The factors indole-3-butyric acid (IBA), 2-morpholineoethanesulfonic acid monohydrate (MES) buffer, and carbon dioxide (CO$_{2}$) were tested on root development and colonization by the fungus. No colonization was observed in the presence of plantlets pre-treated with IBA. The highest levels of root colonization were obtained when plantlets were mycorrhized under a high CO$_{2}$ concentration (1,000 μmol mol$^{−1}$) with MES (10 mM) added to the growth medium. Widespread root colonization (with presence of arbuscules, intraradical mycelium, and spores/vesicles) was predominantly observed in newly produced roots. Therefore, it appears essential to improve root initiation and growth for improving in vitro mycorrhization of H. brasiliensis. We demonstrated the potential of the “mycelium donor plant” in vitro culture system to produce colonized H. brasiliensis plantlets before their transfer to ex vitro conditions. |

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.
