WebAug 14, 2024 · Eukaryotic small RNAs (sRNAs) are short non-coding regulatory molecules that induce RNA interference (RNAi). During microbial infection, host RNAi machinery is highly regulated and contributes to reprogramming gene expression and balancing plant immunity and growth. WebJun 24, 2024 · Abstract. Systemic acquired resistance (SAR) involves the generation of systemically transported signal that arms distal plant parts against secondary infections. We show that two phased 21–nucleotide (nt) trans-acting small interfering RNA3a RNAs (tasi-RNA) derived from TAS3a and synthesized within 3 hours of pathogen infection are the …

WebJan 1, 2024 · In plants, another important class of small endogenous RNAs regulating gene expression is the siRNAs. This class is derived from double-stranded RNA precursors (“double strand” RNA, dsRNA) with perfect pairing, with many of these precursors synthesized by RNA-dependent RNA polymerase (RDR) [27]. WebJul 1, 2002 · The finding of so many small RNAs in plants and animals leads to the logical conclusion that a broad range of processes are affected by this class of RNA. Given the size of these species and the known capacity of intercellular junctions to transport nucleic acids in plants, it is reasonable to propose that small RNAs serve as local or systemic ...
WebFeb 24, 2004 · Abstract. Multicellular eukaryotes produce small RNA molecules (approximately 21–24 nucleotides) of two general types, microRNA (miRNA) and short interfering RNA (siRNA). They collectively function as sequence-specific guides to silence or regulate genes, transposons, and viruses and to modify chromatin and genome structure.
