Phytoplasmas are prokaryotes characterized by small genomes (530-1,350 kbp) and by a limited number of metabolic pathways. To investigate molecular mechanisms involved in pathogenesis, the differential display technique was applied to identify plant genes whose transcription was significantly modified in leaves of Catharanthus roseus infected by 'Candidatus Phytoplasma pyri' phytoplasma. Out of the sixteen genes identified, eleven were up-regulated by phytoplasma presence, while five were downregulated. Identified genes are mainly involved in plant defence/stress responses, signal transduction, protein metabolism and transport, transcriptional regulation, and plant cell wall structure.

Abstract
Phytoplasmas are prokaryotes characterized by small genomes (530-1,350 kbp) and by a limited number of metabolic pathways. To investigate molecular mechanisms involved in pathogenesis, the differential display technique was applied to identify plant genes whose transcription was significantly modified in leaves of Catharanthus roseus infected by 'Candidatus Phytoplasma pyri' phytoplasma. Out of the sixteen genes identified, eleven were up-regulated by phytoplasma presence, while five were downregulated. Identified genes are mainly involved in plant defence/stress responses, signal transduction, protein metabolism and transport, transcriptional regulation, and plant cell wall structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
