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

Translational control in plant antiviral immunity.
TL;DR: A novel strategy of plant antiviral defense based on suppression of host global translation, which is mediated by the transmembrane immune receptor NIK1 (nuclear shuttle protein (NSP)-Interacting Kinase1), is discussed in this review.

Emerging threats of begomoviruses to the cultivation of medicinal and aromatic crops and their management strategies
S. T. Saeed,Abdul Samad +1 more
TL;DR: This review summaries the current research work on begomoviruses affecting MAPs and provides various traditional and advanced strategies for the management of begomviruses and vector in MAPs.

Small but mighty: Functional landscape of the versatile geminivirus-encoded C4 protein.
TL;DR: C4 as discussed by the authors is the only geminiviral protein consistently subjected to positive selection and displays a number of dynamic subcellular localizations, interacting partners, and functions, which can vary between viral species.

TYLCV-Is movement in planta does not require V2 protein
Hagit Hak,Yael Levy,Sam A. Chandran,Eduard Belausov,Abraham Loyter,Moshe Lapidot,Yedidya Gafni +6 more
TL;DR: It is suggested that the setback in virus proliferation, previously ascribed to a movement impediment, is due to lack of silencing-suppression activity.
Journal ArticleDOI
Insights into the control of geminiviral promoters.
TL;DR: The structural and functional features of geminiviral and satellite promoters are discussed along with their regulation by plant and viral proteins, and a pattern is seen to emerge on the regulation of the promoters.

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.
