| Abstract | Four species of Chattonella, which are well known to form red tides that are lethal to fish, were subjected to phylogenetic analysis on the basis of the ribosomal RNA genes (rDNA), 5.8S rDNA, 18S rDNA, 28S rDNA, and the flanking internal transcribed spacers 1 and 2 (ITS1 and ITS2). The 18S rDNA sequences of C. antiqua, C. marina, and C. ovata isolated from different regions in Japan were compared. They were found to be identical with each other in a sequence 1818 bp long. The sequences of the D1/D2 region in the 28S rDNA, 5.8S rDNA, and ITS region that are known to be more variable regions were also found to be identical. These homogeneities of the rRNA gene family revealed the extremely close relatedness of C. antiqua, C. marina, and C. ovata. The sequences of C. verruculosa were different from those of these three species, resulting in an 89.2% homology in the 18S rDNA sequences, 70.4% homology in the D1/D2 region in the 28S rDNA sequences, and an 81.5% homology in 5.8S rDNA sequences and the ITS regions. Chattonella verruculosa was grouped within a single cluster composed of Dictyochophyceae rather than the other species of Raphidophyceae. |

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.
