Journal of General Virology, 2015 Viroid systemic spread involves cell-to-cell movement from initially infected cells via plasmodesmata, long-distance movement within the phloem and again cell-to-cell movement to invade distal tissues including the mesophyll.

Viroid Diseases in Pome and Stone Fruit Trees and Koch’s Postulates: A Critical Assessment
Viruses, 2018 Composed of a naked circular non-protein-coding genomic RNA, counting only a few hundred nucleotides, viroids—the smallest infectious agents known so far—are able to replicate and move systemically in herbaceous and woody host plants, which ...

, 2017 Studies on viroid–host interactions have become essential to understand different aspects of the structure–function relationships in the RNA world. Work on viroid RNA has led to seminal discoveries in RNA biology. Over the last two decades, significant progress has been made as to how viroid RNA traffics within and among cells, and how these noncoding ...

Journal für Kulturpflanzen, 2014 Monitoring the occurrence of virus diseases in plants is important for the implementation of early control measures and prevention of further disease spread. In Poland, in 2004 a health programme for hop was started to eliminate viruses and viroids.

miRNAs and viroids utilize common strategies in genetic signal transfer
Frontiers in Molecular Neuroscience, 2014 Micro RNAs (miRNAs) constitute an 18–25 nucleotide (nt), highly conserved, non-coding, single stranded RNA (ssRNA) family that are the smallest known carriers of highly selective genetic regulatory information in plants and animals (Lukiw et al., 1992 ...

Journal of General Virology, 1988 Summary Recovery of highly purified citrus cachexia viroid (CCaV) was accomplished by serial elution following CF-11 cellulose chromatography of a 2 m-LiCl-soluble nucleic acid preparation. The alternative herbaceous host, cucumber (Cucumis sativus cv. Suyo), yielded greater quantities of the viroid than the highest yielding citrus host, citron (Citrus

Controversies on the origin of life [PDF]
, 2005 Different viewpoints, many with deep philosophical and historical roots, have shaped the scientific study of the origin of life. Some of these argue that primeval life was based on simple anaerobic microorganisms able to use a wide inventory of ...

Cytopathic effects incited by viroid RNAs and putative underlying mechanisms
Frontiers in Plant Science, 2013 Viroids are infectious agents identified only in plants so far. In contrast to viruses, the genome of viroids is composed of a tiny circular RNA (250-400 nt) not coding for proteins, but containing in its compact structure all the information needed for ...
