Impact of Exogenous Application of Potato Virus Y-Specific dsRNA on RNA Interference, Pattern-Triggered Immunity and Poly(ADP-ribose) Metabolism in Potato Plants
Methods for inhibition of viral infection induced by spraying plants with preparations of specific double-stranded RNAs (dsRNAs) are currently being actively developed. Researchers from the Laboratory of functional genomics and plant proteomics, the Laboratory of Molecular Diagnostics and the Laboratory of Molecular Bases of Plant Stress Resistance of the Institute of Bioorganic Chemistry RAS studied the contribution of potato plant treatment with dsRNA against potato virus Y (dsRNA-PVY) to two dsRNA-induced plant defense mechanisms: specific RNA interference (RNAi) and non-specific pattern-triggered immunity (PTI). It has been shown that application of PVY dsRNA in potato plants induced accumulation of both small interfering RNAs (siRNAs), a hallmark of RNAi, and some gene transcripts related to PTI. The results are published in the International Journal of Molecular Sciences. Learn more
