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

Infectivity of cloned begomoviral DNAs: an appraisal
TL;DR: This review compares the various features associated with the above three methods to study infectivity of cloned begomoviral DNAs and concludes that mechanical inoculation with cloned viral DNA using abrasives, Agrobacterium-mediated inoculation (agroinoculation), and bombardment using microprojectiles coated with cloning viral DNA (biolistics) are superior.

Transgenic tobacco plants expressing siRNA targeted against the Mungbean yellow mosaic virus transcriptional activator protein gene efficiently block the viral DNA accumulation.
TL;DR: In this paper, the efficacy of the transgenically expressed intron-spliced hairpin RNA gene of the transcriptional activator protein (hpTrAP) in reducing myMV DNA accumulation was investigated.

TL;DR: In this article, next generation sequencing (NGS) of DNAs amplified by rolling circle amplification from 6 tomato plants with leaf curl symptoms identified a number of monopartite begomoviruses, including tomato yellow leaf curl virus (TYLCV), and a betasatellite (Tomato leaf curl betas Satellite [ToLCB]).

The Agrobacterium tumefaciens Ti Plasmid Virulence Gene virE2 Reduces Sri Lankan Cassava Mosaic Virus Infection in Transgenic Nicotiana benthamiana Plants
TL;DR: The Agrobacterium Ti plasmid virulence gene virE2, encoding a nuclear-localized, single-stranded DNA binding protein, was introduced into Nicotiana benthamiana to develop tolerance against SLCMV and a pronounced reduction in viral DNA accumulation was observed.

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.
