RNA helicase domain of tobamovirus replicase executes cell-to-cell movement possibly through collaboration with its nonconserved region.

UR-hel, a chimeric virus obtained by replacement of the RNA helicase domain of tobacco mosaic virus (TMV)-U1 replicase with that from the TMV-R strain, could replicate similarly to TMV-U1 in protoplasts but could not move from cell to cell (K. Hirashima and Y. Watanabe, J. Virol. 75:8831-8836, 2001). It was suggested that TMV recruited both the movement protein (MP) and replicase for cell-to-ce...

Systemic movement of a tobamovirus requires host cell pectin methylesterase.

Systemic movement of plant viruses through the host vasculature, one of the central events of the infection process, is essential for maximal viral accumulation and development of disease symptoms. The host plant proteins involved in this transport, however, remain unknown. Here, we examined whether or not pectin methylesterase (PME), one of the few cellular proteins known to be involved in loc...

Cell-Free Replicase System

A large-particle fraction obtained from reovirus-infected L cells contained both replicase and transcriptase activity. The in vitro replicase reaction slowed down soon after initiation, whereas the transcriptase reaction proceeded at an unabated rate. The replicase and transcriptase were both template-bound and could be separated from one another by controlled chymotryptic digestion followed by...

Ser/Thr Kinase-Like Protein of Nicotiana benthamiana Is Involved in the Cell-to-Cell Movement of Bamboo mosaic virus

To investigate the plant genes affected by Bamboo mosaic virus (BaMV) infection, we applied a cDNA-amplified fragment length polymorphism technique to screen genes with differential expression. A serine/threonine kinase-like (NbSTKL) gene of Nicotiana benthamiana is upregulated after BaMV infection. NbSTKL contains the homologous domain of Ser/Thr kinase. Knocking down the expression of NbSTKL ...

Rab11 is required for maintenance of cell shape via βPS integrin mediated cell adhesion in Drosophila

In eukaryotes, vesicle trafficking is regulated by the small monomeric GTPases of the Rab protein family. Rab11, (a subfamily of the Ypt/Rab gene family) an evolutionarily conserved, ubiquitously expressed subfamily of small monomeric Rab GTPases, has been implicated in regulating vesicular trafficking through the recycling of endosomal compartment. In an earlier communication, we have shown th...
