REPercussions: how geminiviruses recruit host factors for replication

Frontiers in Microbiology, 2023
Circular single-stranded DNA viruses of the family Geminiviridae encode replication-associated protein (Rep), which is a multifunctional protein involved in virus DNA replication, transcription of virus genes, and suppression of host defense responses ...

Diagnóstico molecular de geminivirus en plantaciones comerciales de tomate (solanum lycopersicum l.) y malezas asociadas al cultivo, en la provincia Santa Elena [PDF]

, 2012
La familia Geminiviridae está actualmente constituida por cuatro géneros, siendo los Begomovirus los de mayor propagación, en parte debido a las características de su principal vector, la mosca blanca (Bemisia tabaci). Esta familia causa daños y pérdidas

Stabilisation of Tomato Yellow Leaf Curl China Virus Infectious Clones Through Micro‐Homology Mediated End Joining

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2187-2200, April 2026.
ABSTRACT Tomato yellow leaf curl China virus (TYLCCNV) is a major agricultural pathogen and primary model for circular single‐stranded DNA (cssDNA) virus studies. The infectious clones of TYLCCNV and other cssDNA viruses are usually constructed as two tandem copies of the small viral genomes in Agrobacterium‐mediated T‐DNA vectors.

Infectivity, effects on helper viruses and whitefly transmission of the deltasatellites associated with sweepoviruses (genus Begomovirus, family Geminiviridae) [PDF]

Scientific Reports, 2016
AbstractBegomoviruses (family Geminiviridae) are whitefly-transmitted viruses with single-stranded DNA genomes that are frequently associated with DNA satellites. These satellites include non-coding satellites, for which the name deltasatellites has been proposed. Although the first deltasatellite was identified in the late 1990s, little is known about

Molecular characterization and identification of bhendi yellow vein mosaic virus with satellite DNAs infecting okra plants of district Mardan, Pakistan

Egyptian Journal of Biological Pest Control, 2022
Background Bhendi or okra (Abelmoschus esculentus) is an important crop widely cultivated in the Indian subcontinent. The production of okra in tropical regions is constrained by several abiotic and biotic factors.

Genomic Variation and Diversification in Begomovirus Genome in Implication to Host and Vector Adaptation

Plants, 2021
Begomoviruses (family Geminiviridae, genus Begomovirus) are DNA viruses transmitted in a circulative, persistent manner by the whitefly Bemisia tabaci (Gennadius). As revealed by their wide host range (more than 420 plant species), worldwide distribution,

Insights Into Virus‐Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops

Physiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.

Distribution and Rate of Movement of the Curtovirus Beet mild curly top virus (Family Geminiviridae) in the Beet Leafhopper [PDF]

Phytopathology®, 2003
A polymerase chain reaction (PCR)-based method for the detection of the curtovirus Beet mild curly top virus (BMCTV, previously named the Worland strain of Beet curly top virus) was developed and used to investigate the BMCTV-beet leafhopper interaction. Using PCR and a BMCTV-specific primer pair, an ≈1.1-kb BMCTV DNA fragment was amplified from adult
