Safety of virus-resistant transgenic plants two decades after their introduction: lessons from realistic field risk assessment studies.
TLDR
This review focuses on safety assessment with a special emphasis on crops that have been commercialized or extensively tested in the field such as squash, papaya, plum, grape, and sugar beet, and recommends realistic risk assessment approaches to assist their timely deregulation and release.
TAXONOMIC REVISION OF THE FAMILY CLOSTEROVIRIDAE WITH SPECIAL REFERENCE TO THE GRAPEVINE LEAFROLL-ASSOCIATED MEMBERS OF THE GENUS AMPELOVIRUS AND THE PUTATIVE SPECIES UNASSIGNED TO THE FAMILY
TLDR
A comparative examination of the amino acid sequence divergence of three taxonomically relevant genes supports the notion that they are all genetically divergent variants of a single species, GLRaV-4, and the establishment of a fourth genus within the family Closteroviridae is justified.
Grapevine leafroll-associated virus 3
TLDR
The characterization of sgRNAs produced during the infection cycle of GLRaV-3 has given some insight into the replication strategy and the putative functionality of the ORFs, and the application of next-generation sequencing is proving to be a valuable tool to study the complexity of viral infection as well as plant pathogen interaction.
Survey for the Three Major Leafroll Disease-Associated Viruses in Finger Lakes Vineyards in New York.
TLDR
The prevalence of the three major leafroll disease-associated viruses in Finger Lakes vineyards results likely from poor sanitary status of planting materials, stressing the need to reinstate a certification program in New York.
Transferring Cucumber Mosaic Virus-White Leaf Strain Coat Protein Gene into Cucumis melo L. and Evaluating Transgenic Plants for Protection against Infections
TLDR
Flow cytometry analysis of leaf tissue revealed that a significant number of transgenic plants were tetraploid or mixoploid, whereas the commercial nontransformed cultivars were diploid, while in a study of young, germinated cotyledons, a mixture of diploids, tetraPloid, and octoploid cells were found at the shoot regeneration sites.
RNA2 of grapevine fanleaf virus: sequence analysis and coat protein cistron location.
TLDR
Comparison of GFLV RNA2 with M RNA of cowpea mosaic comovirus and with RNA2 of two closely related nepoviruses, tomato black ring virus and Hungarian grapevine chrome mosaic virus, showed strong similarities among the 3' non-Coding regions but less similarity among the 5' end non-coding sequences than reported among other nepovirus RNAs.
Complete Genome Sequence of a New Circular DNA Virus from Grapevine
TLDR
A novel circular DNA virus sequence is reported from grapevine that is similar to members of the family Geminiviridae, but the genome is 4% larger than the largest reported geminiviral genome and shares only 50% overall sequence identity.
Grapevine Leafroll: A Complex Viral Disease Affecting a High-Value Fruit Crop.
TLDR
An overview of the state of knowledge on the biology and epidemiology of grapevine leafroll disease is provided and management strategies currently deployed in vineyards are described.
Complete nucleotide sequence and genetic organization of grapevine fanleaf nepovirus RNA1.
TLDR
The location of genome-linked protein and comparison of the primary structure of the 253K polyprotein to that of other closely related viral proteins of the picronavirus-like family allows the proposal of a scheme for the genetic organization of GFLV-F13 RNA1.
