| Abstract | A disease on parthenium weed (Parthenium hysterophorus L.) was observed in June 2008 in Danzhou of Hainan Province. Infected weeds showed phytoplasma-like associated symptoms such as severe stunting, excessive proliferation of shoots, inflorescence-clustering, green petal, small leaves and witches’-broom. The original cause of phytoplasma was further confirmed by polymerase chain reaction (PCR). PCR products of 1.8 kb were obtained using the universal primers pair (P1/P7) designed to amplify the entire 16S rDNA and the 16/23S intergenic spacer region in a direct PCR assay. The primers pair R16F2n/R2 was used to amplify a PCR product of 1.2 kb. Restriction fragment length polymorphism (RFLP) was used to analyze the partial 16S rDNA sequences (1.2 kb) of all phytoplasma DNA digested with five endonucleases (Kpn I, Hpa II, Taq I, Rsa I, EcoR I). The RFLP patterns of the strain were found to be identical with that of the reference peanut witches’-broom phytoplasma. Based on the RFLP data, it is suggested that the phytoplasma strain belongs to subgroup 16SrII-A. This is the first demonstration of a 16SrII-A group phytoplasma associated with parthenium weed. |

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.
