Two isolates of a novel monopartite begomovirus were obtained from naturally infected Ageratum conyzoides plants showing typical leaf curling and enation symptoms in Sichuan Province, China. The complete DNA sequences of two isolates were determined to be 2749 nucleotides in length. Sequence analysis showed that the two isolates shared 99.5% identity, and the highest identity (89.5–89.6%) was with the DNA sequence of tomato leaf curl Hainan virus (ToLCHaiV). No other begomoviruses or satellite…

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
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.
The Malvastrum Yellow Vein Virus C4 Protein Promotes Disease Symptom Development and Enhances Virus Accumulation in Plants
The results indicate that the MaYVV C4 protein is a determinant of disease symptom and viral DNA accumulation and this protein can also function as a suppressor of RNA silencing and alter cell division and expansion.
Geminivirus C4 proteins inhibit GA signaling via prevention of NbGAI degradation, to promote viral infection and symptom development in N. benthamiana
It is demonstrated that geminivirus - encoded C4 protein regulates the GA signaling pathway to promote viral accumulation and disease symptom development and provides new insights into the interaction between virus and host.
Geminivirus C4 proteins inhibit GA signaling via prevention of NbGAI degradation, to promote viral infection and symptom development in N. benthamiana
A novel mechanism by which geminivirus C4 proteins control viral infection and disease symptom development by interfering with the GA signaling pathway is proposed.


Molecular characterization of two distinct begomoviruses from Ageratum conyzoides and Malvastrum coromandelianum in China
The molecular data suggest that G52 and G87 are two distinct begomoviruses, for which the names Ageratum leaf curl virus for G 52 and Malvastrum leaf curlirus for G 87 are proposed.
First Report of Ageratum yellow vein virus Causing Tobacco Leaf Curl Disease in Fujian Province, China.
The presence of the virus and DNAβ in symptomatic plants was verified by PCR with primer pairs TV-Full-F/TV- full-R and beta 01/beta 02, respectively and confirmed that the tobacco samples were infected by AYVV.
Establishment of three new genera in the family Geminiviridae: Becurtovirus, Eragrovirus and Turncurtovirus
This communication highlights the establishment of three new genera to accommodate various recently discovered geminiviruses that are highly divergent and, in some cases, have unique genome architectures.
Revision of Begomovirus taxonomy based on pairwise sequence comparisons
Revised guidelines for the classification and nomenclature of begomoviruses are proposed and genome-wide pairwise identities of 91 % and 94 % are proposed as the demarcation threshold for begomviruses belonging to different species and strains, respectively.

Investigation of the biology of two deltasatellites found in wild malvaceous plants in the New World found that they were not able to spread autonomously in planta, whereas they were maintained by the associated bipartite begomovirus.
Evidence of synergism between African cassava mosaic virus and a new double-recombinant geminivirus infecting cassava in Cameroon.
Southern blot analysis of viral DNAs from infected plants showed that there were significantly higher levels of accumulation of both ACMV/CM components and, to a lesser extent, of EACMV /CM components in mixed-infected plants than in singly infected plants, suggesting the occurrence of a synergistic interaction between the two viruses.
