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

The six Tomato yellow leaf curl virus genes expressed individually in tomato induce different levels of plant stress response attenuation
TL;DR: The dependence of analyzed plant stress response suppression on the interaction of the expressed genes with the environment created by the whole virus infection was more pronounced than on the expression of individual TYLCV genes.

TL;DR: In this paper, the authors used high-throughput sequencing to characterize the accumulation of nucleotide diversity after inoculation of infectious clones corresponding to African cassava mosaic virus (ACMV) and East African Cassava mosaic Cameroon virus (EACMCV) in the susceptible cassava landrace Kibandameno.

CRISPR-Cas9 interference in cassava linked to the evolution of editing-resistant geminiviruses
Devang Mehta,Alessandra Sturchler,Matthias Hirsch-Hoffmann,Wilhelm Gruissem,Hervé Vanderschuren +4 more
TL;DR: This study found that between 33 and 48% of edited virus genomes evolved a conserved single-nucleotide mutation that confers resistance to CRISPR-Cas9 cleavage, highlighting the potential for virus escape from this technology.

Plant-virus-insect tritrophic interactions: insights into the functions of geminivirus virion-sense strand genes.
TL;DR: The essential role of virion-sense strand encoded proteins in transport of viral genomes within and between plant cells, countering defence in hosts (both plants and the insects), and also in the ubiquitous role in vector-mediated transmission is summarized.

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.

Exploiting chinks in the plant's armor: evolution and emergence of geminiviruses
TL;DR: The geminiviruses represent a family of DNA viruses that has circumvented these impediments to emerge as one of the most successful viral pathogens, causing severe economic losses to agricultural production worldwide.
