| Abstract | Northern Europe’s oldest and largest Camellia japonica growing at the Pillnitz Castle (Germany) for over 200 years is of botanical and cultural importance and is a reference for C. japonica molecular scale analysis. In order to provide a fundament for genome analysis of the genus Camellia, we characterize the C. japonica tandem repeat fraction, constituting 12.5 % of the Pillnitz camellia’s genome. A genomic library of the Pillnitz C. japonica was produced and Illumina sequenced to generate 36 Gb of paired-end reads. We performed graph-based read clustering implemented in the RepeatExplorer pipeline to estimate the C. japonica repeat fraction of 73 %. This enabled us to identify and characterize the most prominent satellite DNAs, Camellia japonica satellite 1–4 (CajaSat1–CajaSat4), and the 5S ribosomal DNA (rDNA) by bioinformatics, fluorescent in situ and Southern hybridization. Within the Camellia genus, satellite spreading, array expansion and formation of higher-order structures highlight different modes of repeat evolution. The CajaSat satellites localize at prominent chromosomal sites, including (peri)centromeres and subtelomeres of all chromosomes, thus serving as chromosomal landmarks for their identification. This work provides an insight into the C. japonica chromosome organization and significantly expands the Camellia genomic knowledge, also with respect to the tea plant Camellia sinensis. |

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.
