Insights into Emerging Begomovirus–Deltasatellite Complex Diversity: The First Deltasatellite Infecting Legumes

open access: yesBiology, 2021
Begomoviruses and associated DNA satellites are involved in pathosystems that include many cultivated and wild dicot plants and the whitefly vector Bemisia tabaci. A survey of leguminous plants, both crops and wild species, was conducted in Venezuela, an

Geminivirus Rep Protein Interferes with the Plant DNA Methylation Machinery and Modifies the Host Epigenome [PDF]

open access: yes, 2016
The apparent simplicity of viruses hides the complexity of their interactions with their hosts. Viruses are masters at circumventing host defenses and manipulating the cellular environment for their own benefit.

Attempts to identify Cassava Brown Streak Virus in western Democratic Republic of Congo [PDF]

open access: yes, 2020
Open Access ArticleRoot necrosis similar to those of the cassava brown streak disease (CBSD) were observed on cassava in western provinces of the Democratic Republic of Congo (DR.Congo) in the early 2000’s. However molecular laboratory diagnosis were not

The Transcriptome Response of African and South American Cassava (Manihot esculenta) to Infection by East African Cassava Mosaic Virus‐Uganda

open access: yesPlant Pathology, Volume 74, Issue 4, Page 1068-1077, May 2025.
The early defence response in cassava plants is associated with EACMV‐Ug resistance, while the susceptible varieties' response is delayed and expresses fewer unique differentially expressed genes. ABSTRACT Cassava mosaic begomoviruses (CMBs) cause the economically important cassava mosaic disease (CMD) in cassava.

A novel geminivirus‐derived 3′ flanking sequence of terminator mediates the gene expression enhancement

open access: yesPlant Biotechnology Journal, Volume 23, Issue 4, Page 1053-1066, April 2025.
Summary Exploring the new elements to re‐design the expression cassette is crucial in synthetic biology. Viruses are one of the most important sources for exploring gene expression elements. In this study, we found that the DNA sequence of the SBG51 deltasatellite from the Sweet potato leaf curl virus (SPLCV) greatly enhanced the gene expression when ...

The viral etiology of tomato yellow leaf curl disease - a review

open access: yesPlant Protection Science, 2009
Tomato yellow leaf curl disease (TYLCD) is one of the most devastating plant diseases in the world. As a result of its continuing rapid spread, it now afflicts more than 30 tomato growing countries in the Mediterranean basin, southern Asia, Africa, and ...

Endogenous caulimovirid sequences are widespread in plant genomes [PDF]

open access: yes, 2010
Endogenous sequences from members of the Caulimoviridae and Geminiviridae families have been identified in the genome of several plant species. They are thought to result from illegitimate recombination events and are generally replication-defective ...

Detection and Partial Characterization of Polerovirus and Luteovirus Isolates Associated With Lentil and Chickpea in Ethiopia

open access: yesLegume Science, Volume 7, Issue 1, March 2025.
ABSTRACT The partial nucleotide sequence of the coat protein (CP) gene of Ethiopian isolates of chickpea chlorotic stunt virus (CpCSV, genus Polerovirus), beet western yellows virus (BWYV, genus Polerovirus), and soybean dwarf virus (SbDV, genus Luteovirus) was determined from lentil and chickpea plants showing yellowing, stunting, and reddening ...

Molecular epidemiology, genetic diversity and dissemination routes of CMGs in sub-Saharan Africa and the south-west Indian Ocean (SWIO) islands [PDF]

open access: yes, 2014
Cassava cultivation is associated with a wide range of diseases that seriously undermine the food and economic security in African countries. The most notable of these is CMD, caused by a complex of cassava mosaic geminiviruses (CMGs; Geminiviridae ...
