Properties of Commelina yellow mottle virus's complete DNA sequence, genomic discontinuities and transcript suggest that it is a pararetrovirus.
The non-enveloped bacilliform viruses are the second group of plant viruses known to possess a genome consisting of circular double-stranded DNA and the complete sequence of the genome of Commelina mellow mottle virus (CoYMV), a member of this group, is determined.
Maize Lethal Necrosis (MLN), an Emerging Threat to Maize-Based Food Security in Sub-Saharan Africa.
The results of collaborative research undertaken to understand the biology and epidemiology of maize lethal necrosis in East Africa and to develop disease management strategies are summarized, including identification of MLN-tolerant maize germplasm.
An analysis of the complete sequence of a sugarcane bacilliform virus genome infectious to banana and rice.
Comparisons with the other sequenced badnaviruses, Commelina yellow mottle (CoYMV) and rice tungro bacilliform (RTBV) viruses, indicate that the arrangement of the ORFs in these viruses is conserved.
Evidence that badnavirus infection in Musa can originate from integrated pararetroviral sequences.
This report documents the first instance of integrated DNA of a nonintegrating virus giving rise to an episomal viral infection and identifies tissue culture as a possible trigger for the infection, raising the question of whether similar activatable viral sequences exist in the genomes of other plants and animals.
Sugarcane yellow leaf virus: a novel member of the Luteoviridae that probably arose by inter-species recombination.
Analysis of the genome of Sugarcane yellow leaf virus Florida isolate (SCYLV-F) indicates that it represents a distinct fifth type of luteovirid, which is most closely related to the read-through protein gene of the only known enamovirus.
Banana contains a diverse array of endogenous badnaviruses.
Analysis of rates of non-synonymous and synonymous substitution suggested that the integrated sequences evolved under a high degree of selective constraint as might be expected for a living badnavirus, and that each distinct sequence resulted from an independent integration event.
Association of a badnavirus with citrus mosaic disease in India
The virus, named citrus mosaic badnavirus (CMBV), was graft- and dodder-transmitted to 13 of 14 citrus species and cultivars, and was transmitted by mechanical inoculation from symptomatic citrus to healthy Citrus decumana.
Characterization and genomic analysis of tobacco vein clearing virus, a plant pararetrovirus that is transmitted vertically and related to sequences integrated in the host genome.
Observations suggest that the episomal form of TVCV may arise from integrated pararetroviral elements present in N. edwardsonii, that these integrants were inherited from the male parent N. glutinosa, and that these elements are related but not identical to pararetoviral elements occurring in other Nicotiana spp.
Transmission, characterization, and serology of a luteovirus associated with yellow leaf syndrome of sugarcane.
It is concluded that ScYLV is a previously undescribed luteovirus that is biologically and serologically distinct from other members of the group and may be the causal agent of one form of YLS of sugarcane.
Viral sequences integrated into plant genomes.
