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

A virus-encoded protein suppresses methylation of the viral genome in the Cajal body through its interaction with AGO4
TL;DR: This work shows that the anti-viral methylation of the Tomato yellow leaf curl virus (TYLCV) genome occurs specifically in the Cajal body of Nicotiana benthamiana cells, drawing a long sought-after functional connection between RdDM, the Cjal body, and anti-Viral DNA methylation.

Compatibility and interaction of begomoviruses and DNA-satellites causing leaf curl disease in Asia, Africa and Mediterranean Region
TL;DR: It is confirmed that geographically diverseBegomoviruses can functionally interact with non-cognate DNA-satellites, which may cause the emergence of new begomovirus-satellite complexes.

SnRK1: a versatile plant protein kinase that limits geminivirus infection.
Wei Shen,Linda Hanley-Bowdoin +1 more
TL;DR: Data suggest that SnRK1 is involved in the co-evolution of plant hosts and geminiviruses.

Stability of Begomoviral pathogenicity determinant βC1 is modulated by mutually antagonistic SUMOylation and SIM interactions
Ashwin Nair,Ashwin Nair,Kiran Sankar Chatterjee,Vikram Jha,Vikram Jha,Ranabir Das,Padubidri V. Shivaprasad +6 more
TL;DR: The results indicate the presence of a novel mechanism mediating a fine balance between defence and counter-defence in which a SIM site is competitively sought for degradation and, as a counter-Defence, βC1 undergoes SUMOylation to escape from its degradation.

KU80, a key factor for non-homologous end-joining, retards geminivirus multiplication
Kathrin S. Richter,Holger Jeske +1 more
TL;DR: It is demonstrated that the speed of a systemic infection with a plant DNA geminivirus in Arabidopsis thaliana is KU80-dependent, and the early emergence of Euphorbia yellow mosaic virus DNA was significantly increased in ku80 knockout mutants compared with wild-type sibling controls.

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.

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.

TL;DR: Geminiviruses modulate plant cell cycle status by differentially impacting the CYCD/retinoblastoma-related protein/E2F regulatory network and facilitating progression into the endocycle.
