A role for the endoplasmic reticulum in the cell-to-cell movement of SHORT-ROOT

Protoplasma, 2019
Plasmodesmata enable the trafficking of various signaling molecules, as well as viruses that exploit these channels for their intercellular movement. Viral movement relies on the endoplasmic reticulum (ER), which serves as a stable platform for the assembly of viral replication complexes and their subsequent shuttling toward plasmodesmata.

Phosphorylation of viral movement proteins – regulation of cell-to-cell trafficking

Trends in Microbiology, 2001
In plants, proteins and nucleoprotein complexes can traffic from cell to cell, via plasmodesmata. Studies based on viral movement proteins (MP) have revealed that such trafficking events are likely to be regulated at the level of protein phosphorylation.

Influence of Heterologous Tobamovirus Movement Protein and Chimeric-Movement Protein Genes on Cell-to-Cell and Long-Distance Movement

Virology, 1994
Sunn-hemp mosaic tobamovirus (SHMV) moves slowly from cell to cell in Nicotiana tabacum cv. Xanthi, but fails to move long distance. To determine the role of the SHMV movement protein (MP) in cell-to-cell and long-distance movement in tobacco, the SHMV MP gene was inserted into a TMV-cDNA clone that had approximately the 5'-half of the endogenous MP ...

Cell-to-cell tracer movement in cardiac muscle

Cell And Tissue Research, 1981
An attempt was made to label injured cardiac muscle cells by exposing them to two electron-opaque tracers, ruthenium red and lanthanum nitrate. To do this, false tendons of sheep hearts containing strands of Purkinje fibers were sectioned, allowed to heal, and then exposed to the tracer during fixation.

The Ins and Outs of Nondestructive Cell-to-Cell and Systemic Movement of Plant Viruses

Critical Reviews in Plant Sciences, 2004
Propagation of viral infection in host plants comprises two distinct and sequential stages: viral transport from the initially infected cell into adjacent neighboring cells, a process termed local or cell-to-cell movement, and a chain of events collectively referred to as systemic movement that consists of entry into the vascular tissue, systemic ...

The movement protein gene is involved in the virus-specific requirement of the coat protein in cell-to-cell movement of bromoviruses

Archives of Virology, 2003
Brome mosaic virus (BMV) requires the coat protein (CP) for cell-to-cell movement whereas Cowpea chlorotic mottle virus (CCMV), from the same genus, does not. Chimeric viruses created by exchanging the movement protein (MP) gene between the viruses can move from cell to cell.

Cell-to-cell and long-distance siRNA movement in plants: mechanisms and biological implications

Current Opinion in Plant Biology, 2011
In plants, once triggered within a single-cell type, transgene-mediated RNA-silencing can move from cell-to-cell and over long distances through the vasculature to alter gene expression in tissues remote form the primary sites of its initiation. Although, transgenic approaches have been instrumental to genetically decipher the components and channels ...

Cell-to-Cell Movement of Tobacco Mosaic Virus

1999
Following initial infection, many plant viruses spread from cell to cell through plant intercellular connections, the plasmodesmata. This cell-to-cell movement is mediated by virus-encoded movement proteins (MP) which act to increase plasmodesmal permeability and transport viral nucleic acids through the enlarged plasmodesmal channels (reviewed by ...

Cell movements, cell division and growth in the hydroid Clytia johnstoni

Development, 1964
ABSTRACT In Clytia johnstoni, mitosis is almost exclusively a function of the ectoderm cells; only very rarely does an endoderm cell divide. Thus new endoderm cells must be produced by the ectoderm cells. Cell divisions may occur anywhere in the stolonic ectoderm except for approximately the first 0·3 mm. from a growing tip.
