| Abstract | Isolates of Pyrenochaeta lycopersici, the causal agent of corky root rot on tomato plants, were assessed for physiological and genetic characteristics using conventional and molecular techniques. All isolates were able to produce necrosis on tomato roots and classified into temperature group according to the optimal growth temperatures. Specific-PCR assays and DNA sequence analysis of the ribosomal DNA (rDNA) internal transcribed spacer region confirmed the existence of both types (Type 1 and Type 2) of the pathogen among the isolates tested. All isolates were identified as Type 2 except for isolate Pl-4, which was classified as Type 1. Restriction fragment length polymorphism (RFLP) analysis with six enzymes resulted in three distinct banding patterns among the isolates depending on the length and restriction profiles of the rDNA intergenic spacer region. Inter-simple sequence-repeat analysis revealed a high level of genetic diversity among the isolates in agreement with the data of RFLP analysis. These results indicated that there were three different intraspecific groups among Turkish isolates of P. lycopersici. The presented study is the first attempting to characterize Turkish isolates of P. lycopersici. The results obtained will be useful in screening of tomato seedlings for resistance to P. lycopersici. |

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.
