qPCR Assay as a Tool for Examining Cotton Resistance to the Virus Complex Causing CLCuD: Yield Loss Inversely Correlates with Betasatellite, Not Virus, DNA Titer

Plants, 2023
Cotton leaf curl disease (CLCuD) is a significant constraint to the economies of Pakistan and India. The disease is caused by different begomoviruses (genus Begomovirus, family Geminiviridae) in association with a disease-specific betasatellite. However,

Papain‐Like Cysteine Proteases Contribute to Functional Cleavage of Begomoviral V2 Effector Required for Relevant Virulences

Molecular Plant Pathology, Volume 26, Issue 1, January 2025.
Cotton leaf curl Multan virus uses its V2 protein to promote viral infection through its interaction with a plant papain‐like cysteine protease (NbCP15), which can cleave V2 after the first two amino acids at the N‐terminus. ABSTRACT The begomoviral V2 protein is known to be multifunctional, including its interaction with and inhibition of CYP1, a ...

Transreplication Preference of the Tomato Leaf Curl Joydebpur Virus for a Noncognate Betasatellite through Iteron Resemblance on Nicotiana bethamiana

Microorganisms, 2023
Pepper plants (Capsicum annuum) with severe leaf curl symptoms were collected in 2013 from Bangalore, Karnataka, India. The detection results showed a co-infection between the tomato leaf curl Joydebpur virus (ToLCJoV) and tomato leaf curl Bangladesh ...

Characterisation of a Betasatellite Associated With Tomato Yellow Leaf Curl Guangdong Virus and Discovery of an Unusual Modulation of Virus Infection Associated With C4 Protein

Molecular Plant Pathology, Volume 26, Issue 1, January 2025.
The C4 protein, encoded by tomato yellow leaf curl Guangdong virus (TYLCGdV), does not inhibit PTGS or TGS; the C4 protein modulates TYLCGdV infection by regulating the cytosine methylation level of viral genome at different infection stages. ABSTRACT Tomato yellow leaf curl Guangdong virus (TYLCGdV), a monopartite begomovirus first identified in 2004,

Identification and Analysis of Potential Genes Regulated by an Alphasatellite (TYLCCNA) that Contribute to Host Resistance against Tomato Yellow Leaf Curl China Virus and Its Betasatellite (TYLCCNV/TYLCCNB) Infection in Nicotiana benthamiana

Viruses, 2019
Recently, begomovirus/betasatellite disease complexes were found to be associated with alphasatellites, and their presence modulated disease symptoms and/or viral DNA accumulation in infected plants.

Molecular diversity of Cotton leaf curl Gezira virus isolates and their satellite DNAs associated with okra leaf curl disease in Burkina Faso

Virology Journal, 2010
Okra leaf curl disease (OLCD) is a major constraint on okra (Abelmoschus esculentus) production and is widespread in Africa. Using a large number of samples representative of the major growing regions in Burkina Faso (BF), we show that the disease is ...

Suppressors of RNA Silencing Encoded by the Components of the Cotton Leaf Curl Begomovirus-BetaSatellite Complex

Molecular Plant-Microbe Interactions, 2011
Begomoviruses (family Geminiviridae) are single-stranded DNA viruses transmitted by the whitefly Bemisia tabaci. Many economically important diseases in crops are caused by begomoviruses, particularly in tropical and subtropical environments.

Molecular diagnostic development for begomovirus-betasatellite complexes undergoing diversification: A case study

Virus Research, 2017
At least five begomoviral species that cause leaf curl disease of cotton have emerged recently in Asia and Africa, reducing fiber quality and yield. The potential for the spread of these viruses to other cotton-vegetable growing regions throughout the world is extensive, owing to routine, global transport of alternative hosts of the leaf curl viruses ...

Demonstration of Insect Vector-Mediated Transfer of a Betasatellite between Two Helper Viruses [PDF]

Viruses
Begomoviruses, transmitted by the whitefly Bemisia tabaci, pose significant threats to global agriculture due to their severe impact on various crops. Among the satellite molecules associated with begomoviruses, betasatellites play a crucial role in enhancing disease severity and yield losses.

Next generation sequencing reveals the first presence of Okra enation leaf curl virus and its Betasatellite in diseased Okra plants in Iraq

Journal of Kerbala for Agricultural Sciences
Okra Enation Leaf Curl Virus (OELCuV) is a monopartite Begomovirus often associated with betasatellites and alphasatellites. OELCuV has been reported in different countries. However, it had not yet been reported from Iraq.
