Resistance in transgenic potato expressing the potato leafroll virus coat protein gene
TLDR
In an attempt to obtain coat protein-mediated protection, the coat protein gene of PLRV was inserted into the genomes of both tobacco and potato.Abstract:
In an attempt to obtain coat protein-mediated protection, the coat protein gene of PLRV, which was previously identified and sequenced, was inserted into the genomes of both tobacco and potato. These plants were characterized, the potato plants challenged with PLRV using viruliferous aphids, and virus titers monitored using ELISA. The results were compared to those of the transgenic plants expressing the coat protein of other virusesread more

Pathogen-derived resistance to plant viruses.
TL;DR: Transformation of plants with portions of viral genomes frequently gives rise to lines of plants that are resistant to the virus from which the sequence was derived, which is termed "pathogen-derived resistance."

Barley yellow dwarf viruses.

TL;DR: This review focuses primarily on four research areas in which progress has been most rapid on evidence supporting reclassification of BYDVs into two genera, elucidation of gene function and novel mechanisms controlling gene expression, initial forays into understanding the complex interactions between BYDV virions and their aphid vectors, and replication of a ByDV satellite RNA.

Strategies to protect crop plants against viruses: pathogen-derived resistance blossoms.
TL;DR: It is shown that normal virus replication requires a subtle blend of host- and virus-coded proteins, present in critical relative concentrations and at specific times and places, and any unregulated superimposition of interfering protein or nucleic acid species can result in an apparently virus-resistant plant phenotype.

Genetically modified crops and hybridization with wild relatives: a UK perspective
Alan Raybould,A. J. Gray +1 more
TL;DR: It is concluded that the spread of modified crops and their hybrids with wild relatives can be modelled in the same manner as for unmodified crops.

Molecular Biology of Luteoviruses
M A Mayo,V Ziegler-Graff +1 more
TL;DR: Molecular analysis has shown that the genomes of luteoviruses combine most of the strategies used to express the monopartite genomes of (+) sense ssRNA viruses, and lutenovirus genomes have clearly evolved by recombination among blocks of coding sequence derived from distinct ancestral viruses.
