| Abstract | The mitotic chromosome sets of the larval stages of Phyllodistomum folium infecting three European populations of Dreissena polymorpha were studied using conventional Giemsa staining and karyometrical analysis. The karyotype, described herein for the first time, consisted of nine chromosome pairs (2n=18). The chromosomes were comparatively small and measured from 1.19 μm to 5.22 μm. The first and second longest chromosome pairs were, respectively, approximately 20% and 18% of the mean total chromosome set length and were clearly differentiated from the other seven pairs, which gradually decreased in size. Most chromosomes were biarmed with medially or submedially located centromeres; only pairs 1 and 4 contained subterminally located centromeres. No significant differences in the relative length values of corresponding chromosomes were observed between the three populations studied. The main interpopulation differences were detected in the centromeric index values of some corresponding chromosome pairs. These data, when analysed in conjunction with those of other Gorgoderidae, indicate that the karyotype of P. folium and other species in this family do not show any clear affinities with "typical" plagiorchiate chromosome sets. |

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.
