 ABSTRACT

Changes in climatic conditions has resulted In the expression of newer diseases due to vector multiplication in case of virus and phytoplasma a. In Solanum trilobatum, a typical phyllody symptoms with a pale green colouration in veinal and interveinal region with pinkish patches on leaf lamina , leaf curling with reduced size of upper young leaves developing in to phyllody symptoms were observed . PCR amplicons of expected size (1.8 kb) were obtained in direct PCR amplifications with most of the symptomatic plant samples, followed by nested-PCR amplifications yielded phytoplasma-specific PCR amplicons (1.2 kb) from all plants with phyllody symptoms.Probably this is the first report of occurrence of  Candidatus phytoplasma of S. trilobatum in India

Key words: Solanum trilobatum ,phytoplasma, PCR , phyllody
