TLDR
This Review describes the current knowledge of how geminiviruses interact with their plant hosts and the functional consequences of these interactions.Abstract:
The family Geminiviridae is one of the largest and most important families of plant viruses. The small, single-stranded DNA genomes of geminiviruses encode 5-7 proteins that redirect host machineries and processes to establish a productive infection. These interactions reprogramme plant cell cycle and transcriptional controls, inhibit cell death pathways, interfere with cell signalling and protein turnover, and suppress defence pathways. This Review describes our current knowledge of how geminiviruses interact with their plant hosts and the functional consequences of these interactions.read more

Multifaceted role of geminivirus associated betasatellite in pathogenesis
Prabu Gnanasekaran,Reddy Kishorekumar,Dhriti Bhattacharyya,R. Vinoth Kumar,Supriya Chakraborty +4 more
TL;DR: The molecular aspects of the pathogenesis of betasatellites, including various βC1‐host factor interactions and their effects on the suppression of defence responses of the plants are discussed.

TL;DR: Grapevine red blotch‐associated virus infections disrupt normal berry development and stress responses by altering transcription factors and hormone networks, which result in the inhibition of ripening pathways involved in the generation of color, flavor, and aroma compounds.

Tomato Yellow Leaf Curl Virus V2 Interacts with Host Histone Deacetylase 6 To Suppress Methylation-Mediated Transcriptional Gene Silencing in Plants.
TL;DR: It is shown that V2 interacts directly with a Nicotiana benthamiana histone deacetylase 6 (NbHDA6), a homolog of Arabidopsis HDA6 (AtHDA 6), known to be involved in gene silencing in cooperation with methyltransferase 1 (MET1), which is the first report that viral proteins inhibit TGS by interacting with hist one de acetylase but not by blocking the methyl cycle.

Geminiviruses and Plant Hosts: A Closer Examination of the Molecular Arms Race
TL;DR: This review summarizes what is known about the cellular processes in the continuing tug of war between geminiviruses and their plant hosts at the molecular level and highlights the prospect of employing geminavirus-based vectors in plant genome engineering and the emergence of powerful genome editing tools to confer geminvirus resistance.
Journal ArticleDOI
Small RNA-Omics for Plant Virus Identification, Virome Reconstruction, and Antiviral Defense Characterization.
TL;DR: Deep sequencing and bioinformatics analysis of small RNA population (small RNA-ome) allows not only for universal virus detection and genome reconstruction but also for complete virome reconstruction in mixed infections.

Top 10 plant viruses in molecular plant pathology
Karen-Beth G. Scholthof,Scott Adkins,Henryk Czosnek,Peter Palukaitis,Emmanuel Jacquot,Thomas Hohn,Barbara Hohn,Keith Saunders,Thierry Candresse,Paul Ahlquist,Cynthia Hemenway,Gary D. Foster +11 more
TL;DR: A short review on each virus of the Top 10 list and its importance is presented, with the intent of initiating discussion and debate amongst the plant virology community, as well as laying down a benchmark, as it will be interesting to see in future years how perceptions change and which viruses enter and leave the Top10.

Emerging Virus Diseases Transmitted by Whiteflies
TL;DR: Factors driving the emergence and establishment of whitefly-transmitted diseases include genetic changes in the virus through mutation and recombination, changes inThe vector populations coupled with polyphagy of the main vector, Bemisia tabaci, and long distance traffic of plant material or vector insects due to trade of vegetables and ornamental plants.
