| Abstract | The bacterial species of the genus Xenorhabdus in the family Enterobacteriaceae have a mutualistic association with steinernematid entomopathogenic nematodes (EPNs), which have been used as biological control agents against soil insect pests. In this study we present the genetic and phenotypic characterizations of the Xenorhabdus species isolated from steinernematid nematodes in Japan. The 18 Japanese Xenorhabdus isolates were classified into five bacterial species based on 16S ribosomal RNA (16S rRNA) gene sequences: Xenorhabdus bovienii, Xenorhabdus hominickii, Xenorhabdus indica, Xenorhabdus ishibashii, and Xenorhabdus japonica. There was no genetic variation between the 16S RNA sequences among the three X. ishibashii isolates, 0–0.1% variation among the five X. hominickii isolates, and 0–0.5% among the eight X. bovienii isolates. Phenotypic characterization demonstrated that representative isolates of the five bacterial species shared common characteristics of the genus Xenorhabdus, and only X. hominickii isolates produced indole. Symbiotic association and co-speciation of Xenorhabdus bacteria with Steinernema nematodes from Japan are discussed. |

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.
