| Abstract | We examined STAG-related gene (DjStag) expression in the planarian Dugesia japonica. This species is common in Far Eastern countries. The DjStag cDNA includes 1362 bp and contains a 489-bp open reading frame corresponding to a deduced protein of 162 amino acids, with a 170-bp 5'-UTR and a 703-bp 3'-UTR. Phylogenetic analysis showed that DjStag is an STAG/STAG-like member. We examined the expression pattern of DjStag in this planarian during embryonic development by whole-mount in situ hybridization. DjStag was detected in embryonic cells in the germ band at early embryo stages. The number of DjStag-positive embryonic cells increased in stage 5. Later, it was mainly expressed in lateral region parenchyma. In juveniles, extensive expression of DjStag was observed not only in the head and tail regions, but also in the parenchyma between the epidermis and the gastrodermis. We conclude that DjStag is expressed in the cellular subset that will become the neoblast cells of the adult flatworm. DjStag may play an essential role in spatial and temporal regulation during planarian embryonic development. |

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.
