Characterization of plant miRNAs and small RNAs derived from potato spindle tuber viroid (PSTVd) in infected tomato

Popis výsledku v původním jazyce

To defend against invading pathogens, plants possess RNA silencing mechanisms involving small RNAs. Though they also cause the production of viroid-specific small RNAs (vsRNA), viroids do escape the cytoplasmic silencing mechanism. Viroids with minor sequence variations can produce different symptoms in infected plants, suggesting an involvement of vsRNAs in symptom production. We analyzed by deep sequencing the spectrum of vsRNAs induced by a severe PSTVd strain, AS1, upon infection of tomato plants cvRutgers. Indeed, vsRNAs found with highest frequency mapped to the pathogenicity-modulating domain of PSTVd, supporting an involvement of vsRNAs in symptom production. Furthermore, in PSTVd AS1-infected plants the accumulation of some endogenous miRNAs,which are involved in leaf development via regulation of transcription factors, is suppressed. The latter finding supports the hypothesis that a miRNA-dependent (mis)regulation of transcription factors causes the viroid symptoms.
