Tomato, one of the most important crops cultivated worldwide, has been severely affected by begomoviruses such as the Tomato chlorotic mottle virus (ToCMoV). Virulence factor AC2 is considered crucial for a successful virus–plant interaction and is known to act as a transcriptional activator and in some begomoviruses to function as an RNA silencing suppressor factor. However, the exact functions of the AC2 protein of the begomovirus ToCMoV are not yet established. The aim of the present study… 
The C2 protein of tomato leaf curl Taiwan virus is a pathogenicity determinant that interferes with expression of host genes encoding chromomethylases.
TLDR
In tomato and N. benthamiana, ToLCTWV C2 was found to interfere with expression of genes encoding chromomethylases and interferes with host components involved in DNA methylation.
Chloroplast Proteome of Nicotiana benthamiana Infected by Tomato Blistering Mosaic Virus
TLDR
This work investigated the chloroplast proteomic profile of ToBMV-infected N. benthamiana using bidimensional electrophoresis (2-DE) and mass spectrometry to study the virus-host interaction related to the virus replication and infection, and identified proteins that may be targets of a direct interaction with viral proteins.
Transcriptomic and proteomic analysis of yellow mosaic diseased soybean
TLDR
Yellow mosaic virus infection leads to differential regulation of genes involved in cell cycle, cell-wall biogenesis, chloroplast, photosynthesis, hormone and sulphur assimilation pathways, which may contribute to symptom development in YMV-infected soybean plants.
Suppress to Survive—Implication of Plant Viruses in PTGS
TLDR
The aim of this review is to summarize the role and the mode of action of several functionally characterized RNA silencing suppressors encoded by RNA viruses directly involved in plant–pathogen interactions, and point out that the widely diverse functions, structures, and modes ofaction of viral suppressors can be performed by different proteins, even in related viruses.
Characterization of Local and Systemic Impact of Whitefly (Bemisia tabaci) Feeding and Whitefly-Transmitted Tomato Mottle Virus Infection on Tomato Leaves by Comprehensive Proteomics
Tomato mottle virus (ToMoV) is a single-stranded DNA (ssDNA) begomovirus transmitted to solanaceous crops by the whitefly species complex (Bemisia tabaci), causing stunted growth, leaf mottling, and
Cowpea–Meloidogyne incognita interaction: Root proteomic analysis during early stages of nematode infection
TLDR
Analysis of differential expression of proteins in the contrasting cultivars of cowpea CE 31 (highly resistant) and CE 109 (slightly resistant) during early stages of M. incognita infection suggests that oxidative stress, ubiquitination, and glucosinolate degradation may be part ofcowpeaCE 31 resistance mechanisms in response to nematode infection.

Host responses to transient expression of individual genes encoded by Tomato leaf curl virus.
TLDR
The results reveal that a complex set of interactions between the TLCV gene products and host factors occurs in planta, and these are discussed in relation to the current understanding of TLCv gene function.

TLDR
It is shown that developmental abnormalities caused by transient expression of begomovirus genes correlates with altered levels of developmental miRNAs, the first time this has been shown to be the case.

TLDR
The results provide new insights into the molecular mechanisms underlying geminivirus infections, and at the same time reveal the 2IRGFP/VIGS system as a powerful tool for functional reverse genetics studies.
Functional analysis of gene-silencing suppressors from tomato yellow leaf curl disease viruses.
TLDR
It is found that viral proteins from TYLCV were able to suppress silencing in both hosts, whereas TYLCSV proteins were only effective in tomato.
Expression of geminiviral AC2 RNA silencing suppressor changes sugar and jasmonate responsive gene expression in transgenic tobacco plants
TLDR
How expression of AC2 RSS, derived from African cassava mosaic geminivirus changes transcription profile in tobacco leaves and in flowers is described, which indicates that the changed sugar metabolism may cause significant down-regulation of genes encoding ribosomal proteins, thus reducing the general translation level.
Association of the transcriptional response of soybean plants with soybean mosaic virus systemic infection.
TLDR
A number of transcripts corresponding to genes involved in defence were either downregulated or not affected at the early stages of infection, but upregulated at the late stages, indicating that the plant immune response is not activated until the late time points of infection.
Suppression of RNA Silencing by a Geminivirus Nuclear Protein, AC2, Correlates with Transactivation of Host Genes
TLDR
The results suggest that silencing suppression and transcription activation by AC2 are functionally connected and that some of the AC2-inducible host genes discovered here may code for components of an endogenous network that controls silencing.
