| Abstract | Meeting the challenge of routine gene targeting (GT) in higher plants is of crucial interest to researchers and plant breeders who are currently in need of a powerful tool to specifically modify a given locus in a genome. Higher plants have long been considered the last lineage resistant to targeting technology. However, a recent report described an efficient method of T-DNA-mediated targeted disruption of a non-selectable locus in rice [Terada et al., Nat Biotechnol 20: 1030–1034 (2002)]. Though this study was an obvious breakthrough, further improvement of GT frequencies may derive from a better understanding of the natural mechanisms that control homologous recombination (HR) processes. In this review, we will focus on what is known about HR and the factors which may hamper the development of routine GT by HR in higher plants. We will also present the current strategies envisaged to overcome these limitations, such as expression of recombination proteins and refinements in the design of the transformation 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.
