| Abstract | Due to their sessile existence, plants rely on rapid, well-adapted responses to environmental stresses. A common response to these stressors is the activation of secondary metabolism and the production of defense compounds. Catharanthus roseus provides a useful model for studying secondary defense pathways as it produces numerous terpenoid indole alkaloids in response to environmental stressors, such as wounding or the presence of a pathogen. Furthermore, several of these alkaloids are pharmaceutically valuable, including the anticancer drugs vincristine and vinblastine. However, these drugs are very expensive because of their low concentrations in the plant. Over the last decade, there has been remarkable advancement in the understanding of alkaloid biosynthesis, including the sequencing of biosynthetic enzymes, discovery of transcription factors regulating biosynthesis, and elucidation of the pathway induced by the plant hormone jasmonate. Jasmonate has been shown to initiate alkaloid production by inducing expression of a network of transcription factors, including the repressor ZCT. ZCT1 is a key transcriptional repressor of terpenoid indole alkaloid biosynthesis in C. roseus. Here, we report the sequencing and analysis of the Zct1 promoter. |

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.
