Despite the rapid mutational change that is typical of positive-strand RNA viruses, enzymes
mediating the replication and expression of virus genomes contain arrays of conserved …

This review provides a contemporary statement on progress in studies on plasmodesmata
under the following headings: structure, formation, distribution and frequency, symplastic …

CmPP16 from Cucurbita maxima was cloned and the protein was shown to possess
properties similar to those of viral movement proteins. CmPP16 messenger RNA (mRNA) is …

Many eukaryotic RNA viruses transcribe subgenomic (sg) mRNAs during infections to
control expression of a subset of viral genes. Such transcriptional events are commonly …

Publisher Summary This chapter emphasizes the developments in the molecular biology
tombusviridae, and the significant results of the studies on this subject are reviewed and …

The RNAs of many plant viruses lack a 5′ cap and must be translated by a cap-
independent mechanism. Here, we discuss the remarkably diverse cap-independent …

Evidence for RNA recombination in plant viruses with single-stranded RNA genomes is
reviewed under the headings: natural recombination in the evolution of plant viruses; de …

Direct evidence is presented for cell-to-cell trafficking of macromolecules via
plasmodesmata in higher plants. The fluorescently labeled 35-kD movement protein of red …

Publisher Summary This chapter summarizes the present status of our knowledge of plant
virus transport function (TF) by viruses belonging to different taxonomic groups and of the …

Assembly of viral replicase complexes of eukaryotic positive-strand RNA viruses is a
regulated process: multiple viral and host components must be assembled on intracellular …
