| Abstract | KEY MESSAGE: Using Illumina sequencing technology, we have generated the large-scale transcriptome sequencing data and indentified many putative genes involved in isoflavones biosynthesis in Pueraria lobata. Pueraria lobata, a member of the Leguminosae family, is a traditional Chinese herb which has been used since ancient times. P. lobata root has extensive clinical usages, because it contains a rich source of isoflavones, including daidzin and puerarin. However, the knowledge of isoflavone metabolism and the characterization of corresponding genes in such a pathway remain largely unknown. In this study, de novo transcriptome of P. lobata root and leaf was sequenced using the Solexa sequencing platform. Over 140 million high-quality reads were assembled into 163,625 unigenes, of which about 43.1% were aligned to the Nr protein database. Using the RPKM (reads per kilo bases per million reads) method, 3,148 unigenes were found to be upregulated, and 2,011 genes were downregulated in the leaf as compared to those in the root. Towards a further understanding of these differentially expressed genes, Gene ontology enrichment and metabolic pathway enrichment analyses were performed. Based on these results, 47 novel structural genes were identified in the biosynthesis of isoflavones. Also, 22 putative UDP glycosyltransferases and 45 O-methyltransferases unigenes were identified as the candidates most likely to be involved in the tailoring processes of isoflavonoid downstream pathway. Moreover, MYB transcription factors were analyzed, and 133 of them were found to have higher expression levels in the roots than in the leaves. In conclusion, the de novo transcriptome investigation of these unique transcripts provided an invaluable resource for the global discovery of functional genes related to isoflavones biosynthesis in P. lobata. |

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.
