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

Plant DNA polymerases alpha and delta mediate replication of geminiviruses
Mengshi Wu,Mengshi Wu,Hua Wei,Huang Tan,Shaojun Pan,Qi Liu,Eduardo R. Bejarano,Rosa Lozano-Durán +7 more
TL;DR: It is shown that subunits of the nuclear replicative DNA polymerases α and δ physically interact with the geminivirus-encoded replication enhancer protein, C3, and are required for viral replication.

Molecular characterization of Hollyhock leaf curl virus and associated DNA-satellites infecting Malva parviflora in Pakistan
TL;DR: This is the first report of a complete monopartite begomovirus complex from M. parviflora in Pakistan, and these are the new isolates of ACSLA and AYVIA identified.

Tomato mottle wrinkle virus, a recombinant begomovirus infecting tomato in Argentina.
TL;DR: The molecular characterization of a novel tomato-infecting begomovirus isolated in Argentina is presented and its infectivity is demonstrated, with proposed naming the virus tomato mottle wrinkle virus (ToMoWrV), based on symptoms produced upon its biolistic inoculation into tomato plants.

Method of inhibiting plant virus pathogen infections by crispr/cas9-mediated interference
Magdy M. Mahfouz,Zahir Ali +1 more
TL;DR: In this article, a genetically modified tobacco plant or tomato plant resistant to at least one pathogenic geminivirusidae virus species is provided, the plant comprises a heterologous CRISPR/Cas9 system and at least 1 heterology sequence that is capable of hybridizing to a nucleotide sequence of the pathogenic virus.

Evidence for the splicing of grablovirus transcripts reveals a putative novel open reading frame.
TL;DR: Comparative analyses of full-length GRBV sequences and the related tentative grabloviruses Prunus geminivirus A and wild Vitis virus 1 support the existence of both introns and V0.

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.
