| Abstract | The removal or reduction in concentration of auxin is often a successful method for obtaining morphogenesis in cell cultures of higher plants, such as carrot, but not for soybean. For this reason, the metabolism of one auxin, 2,4-dichlorophenoxyacetic acid (2,4-D), was compared in both carrot and soybean cells. Whereas soybean cells conjugated a high percentage of their 2,4-D to amino acids, carrot cells contained primarily free 2,4-D. Moreover, after long-term exposure to 2,4-D, carrot cells released much more 2,4-D upon transfer to 2,4-D-free (embryogenic) medium than did soybean cells. It appears that the retention of 2,4-D by soybean cells might interfere with subsequent morphogenesis. Because no impairment of 2,4-D efflux was found with short-term exposure to radiolabeled 2,4-D, it was concluded that 2,4-D retention in soybean cells might be due to a time-dependent, metabolic process. The conjugation of 2,4-D to amino acids was shown to be one such time-dependent process. Additionally, the release of 2,4-D from the cells was shown to be due primarily to a loss of free 2,4-D and not 2,4-D-amino acid conjugates. It seems that the greater retention of 2,4-D by soybean cells upon transfer to 2,4-D-free medium is due to greater formation of 2,4-D-amino acid conjugates. |

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.
