Detection of genome-scale ordered RNA structure (GORS) in genomes of positive-stranded RNA viruses:Implications for virus evolution and host persistence [PDF]

, 2004
Discrete RNA secondary and higher-order structures, typically local in extent, play a fundamental role in RNA virus replication. Using new bioinformatics analysis methods, we have identified genome-scale ordered RNA structure (GORS) in many genera and ...

RNA-dependent RNA polymerases of plants [PDF]

Proceedings of the National Academy of Sciences, 1979
The existence of RNA-dependent RNA polymerases (EC 2.7.7.48) in plants has been definitely proven by their isolation in pure form from cucumber and tobacco in our laboratory and from cowpea at Wageningen. These enzymes are single-chain proteins of 100-130 kilodaltons. They show clear physical and biochemical differences characteristic for a given plant

Plant organellar RNA maturation

The Plant Cell, 2023
AbstractPlant organellar RNA metabolism is run by a multitude of nucleus-encoded RNA-binding proteins (RBPs) that control RNA stability, processing, and degradation. In chloroplasts and mitochondria, these post-transcriptional processes are vital for the production of a small number of essential components of the photosynthetic and respiratory ...

A parasitic fungus employs mutated eIF4A to survive on rocaglate-synthesizing Aglaia plants

eLife, 2023
Plants often generate secondary metabolites as defense mechanisms against parasites. Although some fungi may potentially overcome the barrier presented by antimicrobial compounds, only a limited number of examples and molecular mechanisms of resistance ...

Plant pathogenic RNAs and RNA catalysis [PDF]

Nucleic Acids Research, 1997
The rolling circle replication of small circular plant pathogenic RNAs requires a processing step to convert multimeric intermediates to monomers which are then circularized. Eleven such RNAs are known so far, two are viroids, one is viroid-like and the remainder are satellite RNAs dependent on a helper virus for replication. The processing step is RNA-

Nucleotide bias of DCL and AGO in plant anti-virus gene silencing [PDF]

, 2010
Plant Dicer-like (DCL) and Argonaute (AGO) are the key enzymes involved in anti-virus post-transcriptional gene silencing (AV-PTGS). Here we show that AV-PTGS exhibited nucleotide preference by calculating a relative AV-PTGS efficiency on processing ...

Unleashing the power within short-read RNA-seq for plant research: Beyond differential expression analysis and toward regulomics

Frontiers in Plant Science, 2022
RNA-seq has become a state-of-the-art technique for transcriptomic studies. Advances in both RNA-seq techniques and the corresponding analysis tools and pipelines have unprecedently shaped our understanding in almost every aspects of plant sciences ...

The Crucial Role of Chloroplast-Related Proteins in Viral Genome Replication and Host Defense against Positive-Sense Single-Stranded RNA Viruses [PDF]

The Plant Pathology Journal, 2023
Plant viruses are responsible for worldwide production losses of numerous economically important crops. The most common plant RNA viruses are positive-sense single-stranded RNA viruses [(+)ss RNA viruses].

Next generation sequencing for studying viruses and RNA silencing-based antiviral defense in crop plants [PDF]

, 2014
The main objectives of this work have been to use next generation sequencing (NGS) and develop bioinformatics tools for plant virus diagnostics and genome reconstruction as well as for investigation of RNA silencing-based antiviral defense.
