The begomovirus C4 protein is required for disease symptom development during virus infection in host plants. It can reprogram the cell cycle process for more efficient virus accumulation. In this study, we showed that the Malvastrum yellow vein virus (MaYVV) C4 protein could cause leaf up-ward curling and flower malformation, and increase virus accumulation in plants using PVX-based transient expression technology. We also demonstrated that, in the presence of its cognate betasatellite DNA…

The C5 protein encoded by Ageratum leaf curl Sichuan virus is a virulence factor and contributes to the virus infection
Evidence is provided showing that Ageratum leaf curl Sichuan virus (ALCScV), a monopartite begomovirus, also encodes a C5 protein that is important for disease symptom formation and can affect viral replication.
Analysis of Pathogenicity and Virulence Factors of Ageratum leaf curl Sichuan virus
Ageratum leaf curl Sichuan virus (ALCScV) is a novel monopartite begomovirus, which was identified from Ageratum conyzoides plants in Sichuan Province, China. In this study, we showed that ALCScV can
Identification of Crucial Amino Acids in Begomovirus C4 Proteins Involved in the Modulation of the Severity of Leaf Curling Symptoms
A new function of begomovirus C4 proteins involved in the modulation of leaf curling severity during symptom formation is revealed and potential applications for managing viral diseases through manipulating the symptoms are suggested.
Suppression of nbe‐miR166h‐p5 attenuates leaf yellowing symptoms of potato virus X on Nicotiana benthamiana and reduces virus accumulation
The results indicate the association of nbe‐miR166h‐p5 with symptoms of PVX and also with those of TuMV, providing useful information on the relationship between miRNA and viral infection.
Rhizosphere Virology and Plant Health
Plants have developed defence strategies involving electrical signalling, using reactive oxygen species and involve the role of different plant hormones in a signalling cascade that prevents the plant from further damage and also intimates its neighbouring plant to prepare themselves for a forthcoming attack.
Positive selection and intrinsic disorder are associated with multifunctional C4(AC4) proteins and geminivirus diversification
It is suggested that non-synonymous mutations and mutations that increase the length of C4(AC4) drive protein diversity that is intrinsically disordered, which could explain C4/AC4 functional variation and contribute to both geminivirus diversification and host jumping.
Characterization of Pathogenicity-Associated V2 Protein of Tobacco Curly Shoot Virus
An Agrobacterium infiltration-mediated transient expression assay indicated that TbCSV V2 can suppress local and systemic RNA silencing and deletion analyses demonstrated that the amino acid region 1–92 of V2, including the five predicted α-helices, are required for local RNAsilencing suppression.


C4 protein of Beet severe curly top virus is a pathomorphogenetic factor in Arabidopsis
Results suggest that the Curtovirus C4 proteins are involved actively in host cell-cycle regulation to recruit host factors for virus replication and symptom development.
Geminivirus C4 protein alters Arabidopsis development
Results indicate that ectopic expression of the BCTV C4 protein in A. thaliana drastically alters plant development, possibly through the disruption of multiple hormonal pathways.
Induction of plant cell division by beet curly top virus gene C4
In situ hybridization is used to show that BCTV infection is closely associated with the vascular system in these hosts, although hyperplastic cells associated with wild-type virus infection frequently do not contain detectable levels of viral DNA.
Involvement of C4 Protein of Beet Severe Curly Top Virus (Family Geminiviridae) in Virus Movement
The results suggest that C4 protein in BSCTV is involved in symptom production and may facilitate virus movement instead of virus replication.
Movement of tomato yellow leaf curl geminivirus (TYLCV): involvement of the protein encoded by ORF C4.
The results strongly suggest that the ORF C4 encodes a protein involved in virus movement, a novel finding for whitefly-transmitted geminiviruses.
Tobacco curly shoot virus DNAbeta Is Not Necessary for Infection but Intensifies Symptoms in a Host-Dependent Manner.
It is demonstrated that only 11 isolates were associated with DNAbeta among 39 Tobacco curly shoot virus (TbCSV)-infected, field-collected samples, which indicates that Tb CSV DNAbeta is not necessary for infection but intensifies symptoms in a host-dependent manner and may represent an evolutionary intermediate between the DNAbeta requiring begomoviruses and the truly monopartite begomviruses.
Efficient infection of Nicotiana benthamiana by Tomato bushy stunt virus is facilitated by the coat protein and maintained by p19 through suppression of gene silencing.
The CP likely enables efficient viral unloading from the vascular system in the form of assembled virions, whereas p19 enhances systemic infection by suppressing the virus-induced gene silencing.
Cotton Leaf Curl Multan virus C4 protein suppresses both transcriptional and post-transcriptional gene silencing by interacting with SAM synthetase
It is reported that Cotton Leaf Curl Multan virus (CLCuMuV) C4 protein interacts with S-adenosyl methionine synthetase (SAMS), a core enzyme in the methyl cycle, and inhibits SAMS enzymatic activity.
A recombinant begomovirus resulting from exchange of the C4 gene.
The results indicate that TLCYnV evolved from TYLCCNV by recombination, acquiring a more virulent C4, allowing it to dispense with the requirement for a betasatellite.
