Phloem transport of plant viruses is an essential step in the setting-up of a complete infection
of a host plant. After an initial replication step in the first cells, viruses spread from cell-to-cell …

Several RNA virus genera belonging to the Virgaviridae and Flexiviridae families encode
proteins organized in a triple gene block (TGB) that facilitate cell-to-cell and long-distance …

Fluorescent proteins (FPs) based on green fluorescent protein (GFP) are widely used
throughout cell biology to study protein dynamics, and have extensive use as reporters of …

Publisher Summary This chapter provides information referring to studies carried out on
potato or presumes that the vectors known for a virus also transmit it on potato. Symptoms …

Many plant viruses exploit a conserved group of proteins known as the triple gene block
(TGB) for cell-to-cell movement. Here, we investigated the interaction of two TGB proteins …

Plant viruses move systemically in plants through the phloem. They move as virions or as
ribonucleic protein complexes, although it is not clear what these complexes are made of …

Highlights•In many viruses, most individual virions fail to initiate a productive infection. In
addition to obvious genetic and/or structural defects, the interactions with the host as well as …

Citrus tristeza virus (CTV), a member of the Closteroviridae, possesses a 19.3-kb positive-
stranded RNA genome that is organized into twelve open reading frames (ORFs). The CTV …

Potato virus Y (PVY) and Potato mop-top virus (PMTV) are viruses whose geographical
distribution is expanding and economic losses are increasing, in contrast to most of other …

▪ Abstract The genome structures of a large number of viruses transmitted by olpidium and
plasmodiophorid vectors have been determined. The viruses are highly diverse, belonging …
