| Abstract | Enkianthus is the most basal extant genus in the phylogeny of ericaceous plants. Its members harbor arbuscular mycorrhiza (AM)-like hyphal structures in their roots but, as yet, no study has surveyed the AM fungal species component. Roots from six species of Enkianthus were collected from five distantly located sites in Japan. Intracellular hyphal coils were observed in the root cortical cells of all species. Fungal DNA sequences of the small subunit ribosomal RNA gene were obtained from 73 of 75 segments of Enkianthus campanulatus roots by PCR using either AML2 or NS31/AM1primer pairs. Results indicated that all E. campanulatus trees were extensively associated with Glomus spp. A phylogenetic analysis showed that 71 root segments harbored fungi belonging to Glomus group A. Among eight delineated clades, seven did not nest with any known AM fungal species. One clade was detected in all roots at all sites at relatively high frequencies, but the rest were detected sporadically at each site. The placement of sequences from distantly located sites into a single clade without known AM fungal species suggests the common association of E. campanulatus with particular AM fungal taxa. |

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.
