| Abstract | The contents of artemisinin and artemisinic acid were monitored in the Artemisia annua plants treated with GA$_{3}$ at vegetative and flowering initiation stages. The highest artemisinin content was observed at full bloom. The decrease in artemisinic acid content occurred during the transition from the vegetative stage to the beginning of flowering. Endogenous GA$_{3}$ content in the leaves peaked at full bloom. At the vegetative stage, in plants treated with various concentrations of GA$_{3}$ , the content of artemisinin increased while that of artemisinic acid decreased. Apparently, the rate-limiting step in artemisinin biosynthesis was from artemisinic acid to artemisinin. The “bottleneck” of artemisinin biosynthesis was probably unlocked during the flowering or in the vegetative plants treated with GA$_{3}$ , which triggered off the conversion of artemisinic acid to artemisinin. |

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.
