| Abstract | Plasmids belonging to various incompatibility (Inc) groups were introduced into the efficiently root-colonizing strain Pseudomonas fluorescens WCS365, and their stabilities in complex and minimal media and in the rhizospheres of tomato, wheat, and potato plants grown under gnotobiotic conditions without selection pressure were tested. The IncP plasmid was found to be highly unstable under all conditions tested, whereas the IncQ and IncW plasmids showed intermediate stabilities and the plasmids pVSP41 and pWTT2081, for which the Inc group is unknown, both containing the origin of replication (rep) and stability (sta) regions of the Pseudomonas aeruginosa pVS1 replicon, were stably maintained under all conditions tested. Growth experiments in which cells of strain WCS365 carrying the plasmid pWTT2081 were grown in the presence of WCS365 without the plasmid showed that the presence of pWTT2081 acts as a burden. We conclude that pVSP41 and pWTT2081 are valuable as stable vectors for the functional analysis of genes involved in root colonization, provided that control cells carry the empty vector. |

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.
