| Abstract | The pinewood nematode Bursaphelenchus xylophilus is the causative agent of pine wilt disease, which has caused heavy economic losses to the South Korean forest industry. In this study, we investigated the genetic variation among South Korean pinewood nematodes using newly developed microsatellite loci. In order to ensure sufficient templates for the amplification of multiple loci required for individual identification, we employed an amplifying step of restricted fragments during the microsatellite development procedure. We found atypical genetic patterns in this non-native pest species: high allelic diversity and population structure. The large number of alleles may be the result of continuous and/or large-scaled introduction, which apparently went unnoticed before the first official report of pine wilt disease in Korea in 1998, or may come from gene pools of closely related species through genetic introgression after hybridization. Ecological properties of this species, such as a vector-mediated life cycle, may have contributed to its population structure, which may be enhanced by governmental efforts to prevent dispersal of this disease. As a geographic population structure was not observed, geographic patterns of genetic variation appear to be more affected by anthropogenic mediation than by natural dispersion through vector insects. And genotypes of Korean populations were compared to genotypes found in neighboring countries such as China and Japan. |

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.
