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

Geminivirus-Encoded Proteins: Not All Positional Homologs Are Made Equal
Ana P. Luna,Rosa Lozano-Durán +1 more
TL;DR: Geminiviruses can be used as probes to deepen the understanding not only of plant-virus interactions, but also of different aspects of plant biology.

Hexanoic Acid Treatment Prevents Systemic MNSV Movement in Cucumis melo Plants by Priming Callose Deposition Correlating SA and OPDA Accumulation.
Emma Fernández-Crespo,José A. Navarro,Marta Serra-Soriano,Ivan Finiti,Pilar García-Agustín,Vicente Pallás,Carmen González-Bosch +6 more
TL;DR: The basal response of melon to Melon necrotic spot virus (MNSV) is studied and the efficacy of hexanoic acid (Hx) priming is demonstrated, which prevents the virus from systemically spreading.
Journal ArticleDOI
The recombination mediator RAD51D promotes geminiviral infection
TL;DR: The results show that the RAD51 paralog RAD51D, rather than RAD51 itself, promotes viral replication at early stages of infection, and a model to implicate single-strand annealing recombination in geminiviral recombination-dependent replication is proposed.

Recent advances on the plant manipulation by geminiviruses.
TL;DR: An overview of the different steps in the geminiviral invasion of the host plant is offered, and the knowns and unknowns in Geminivirus biology are explored.

TL;DR: It is established that SnRK1 phosphorylates Rep and interferes with geminivirus replication and infection, underscoring the emerging role for SnRk1 in the host defense response against plant pathogens.

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.
