| Abstract | Idesia polycarpa Maxim. is a dioecious species. Because of the lack of morphological and cytological methods available for identifying its sex during the long juvenile stage, the application of molecular markers in sex identification may facilitate sex determination in the seedling stage. The objective of this study was to use sequence-related amplified polymorphism to identify sex-linked markers in I. polycarpa and convert these markers into sequence-characterized amplified region markers, which are much easier to identify. A total of 342 primer combinations were screened and 2770 bands were examined. Only me14/em8 could amplify a specific fragment (210 base pairs) in all female but none in male plants. We analyzed this fragment using GenBank and found that the sequence similarity was 80% to the Populus trichocarpa clone POP006-H09 (sequence ID: gb|AC212923.1|) and that of the deduced amino acid sequence was 73% to the integrase of Mendicago truncatula (sequence ID: gb|ABD28291.1|) and 71% to the predicted retrotransposon integrase-like protein 1-like in Cicer arietinum (sequence ID: ref|XP 004515460.1|) (NCBI database through December 17, 2013). This fragment was converted into a stable and simple sequence-characterized amplified region marker approximately 200 base pairs in length. This marker can be utilized for early sexual identification in I. polycarpa, which will facilitate future breeding programs. |

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.
