| Abstract | Lysobacter spp. are well known as biocontrol agents acting against fungal pathogens and root-knot nematode disease, which cause serious losses in a wide range of crops. In this study, the roles of the lytic enzymes from Lysobacter capsici YS1215, isolated from soil in Korea, was investigated for the biocontrol of root-knot nematode under in vitro and in vivo conditions. Chitinase and gelatinase activities of L. capsici YS1215 were enhanced by second stage nematode eggs and juveniles of Meloidogyne incognita into medium as substrates. The activities were confirmed by SDS-PAGE with active bands in chitinase active staining and gelatin zymography. The results clearly indicated that application of bacterial cultures and crab shell powder significantly increased the chitinase and gelatinase activities, as well as the population of chitinolytic and gelatinolytic bacteria in the rhizosphere. Furthermore, L. capsici YS1215 also promoted growth of shoot due to a decrease in the severity of disease caused by M. incognita in comparison with the control (fertilizer treatment). These results demonstrated that L. capsici YS1215 and its lytic enzymes played an important role in the suppression of M. incognita infection, and are likely to provide an alternative to synthetic nematicides used for the control of root-knot nematodes infections in tomato plants. |

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.
