Co-Acquired Nanovirus and Geminivirus Exhibit a Contrasted Localization within Their Common Aphid Vector

open access: yesViruses, 2020
Single-stranded DNA (ssDNA) plant viruses belong to the families Geminiviridae and Nanoviridae. They are transmitted by Hemipteran insects in a circulative, mostly non-propagative, manner.

Mutational analysis of potato yellow mosaic geminivirus

open access: yesJournal of General Virology, 1995
Mutations have been inserted into the virion and complementary sense ORFs encoding proteins with M(r)s in excess of 9 kDa of both DNA A and DNA B of potato yellow mosaic geminivirus (PYMV). Wild-type and mutant monomeric clones were tested for their ability to replicate, produce PYMV-specific DNA, spread and cause symptoms in Nicotiana benthamiana ...

A Shift in Begomovirus coheni Populations Associated With Tomato Yellow Leaf Curl Disease Infecting Tomato Cultivars in the Southeastern United States

open access: yesPlant Pathology, Volume 74, Issue 5, Page 1277-1289, June 2025.
A shift in Begomovirus coheni populations associated with tomato yellow leaf curl disease (TYLCD) in tomato cultivars might facilitate the emergence of tomato yellow leaf curl virus‐Georgia (TYLCV‐GA) in natural conditions. ABSTRACT Tomato yellow leaf curl virus (TYLCV) is a major pathogen causing tomato yellow leaf curl disease (TYLCD), significantly ...

MultipleCisElements Contribute to Geminivirus Origin Function

open access: yesVirology, 1998
The genome of the geminivirus tomato golden mosaic virus (TGMV) consists of two circular DNA molecules which are dissimilar in sequence except for a highly conserved 200-bp common region that includes the origin for rolling circle replication. To better characterize the plus-strand origin, we analyzed the capacities of various TGMV common region ...

Viral Metagenomics: Analysis of Begomoviruses by Illumina High-Throughput Sequencing

open access: yesViruses, 2014
Traditional DNA sequencing methods are inefficient, lack the ability to discern the least abundant viral sequences, and ineffective for determining the extent of variability in viral populations. Here, populations of single-stranded DNA plant begomoviral
