Project description:In order to analyze the production of small RNA (sRNA) by viroids upon infecting the plants, the tomato plants (Lycopersicum esculentum cv. Rutgers) were inoculated with the variants of Potato spindle tuber viroid (PSTVd). After 21-days of post inoculation, total RNA was extracted and subjected for deep-sequencing using Illumina platform. The primers were trimmed and only 21- to 24-nt long small RNAs were filtered after quality check of the raw data. The filtered 21- to 24-nt was mapped against the genomic and antigenomic strands of the respective PSTVd variants using standard pattern matching algorithm. The profiling of viroid derived sRNA (vd-sRNA) revealed that the viroids are susceptible to host RNA silencing mechanism.

Project description:Potato (Solanum tuberosum L) is a natural host of Potato spindle tuber viroid (PSTVd) which can cause characteristic symptoms on developing plants including stunting phenotype and distortion of leaves and tubers. PSTVd is the type species of the family Pospiviroidae, it can replicate in the nucleus and the viroid RNA moves systemically in infected plants. Its KF440-2 strain can cause severe symptoms in potato. It is not well understood how the viroid can affect host genes for successful invasion and which genes show altered expression levels upon infection. In this study, we used a high-scale method to identify differentially expressed genes in potato. We have identified defence, stress and sugar metabolism related genes having altered expression levels upon infection. Additionally, hormone pathways connected genes showed up- or down-regulation. Our primary focus is on the identification of genes which can affect tuber formation as the viroid infection can strongly influence tuber development, especially tuber shape is affected. DWARF1/DIMINUTO, Gibberellin 7-oxidase and BEL5 protein were identified and validated which showed differential expression in viroid infected tissues suggesting that gibberellin and brassinosteroid pathways have a possible role in tuber development upon PSTVd infection.

Project description:Using a high-throughput sequencing approach we quantitatively analyzed the content of viroid-derived siRNAs of an infected tree. Our results show that the entire PLMVd genome is found in the siRNA population. Also both polarities are susceptible to be targeted by the RNAi machinery but specific regions for each polarity are over represented. Those regions, that are not the same for each polarity, do not necessarily correlate with double stranded regions that could be substrate for Dicer-like enzymes. Finally the analysis of the first 5’ nucleotide revealed a bias toward a C or a U in viroid-derived siRNAs, indicating that at least AGO5 and AGO1 can recruit these small RNAs.
