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

Functional analysis of V2 protein of Beet curly top Iran virus
Ana Luna,Paige Rozanski +1 more
TL;DR: In this article , the geminivirus beet curly top Iran virus (BCTIV) was shown to be a strong local silencing suppressor in Nicotiana benthamiana and can delay the systemic silencing spreading, although it cannot block the cell-tocell movement of the silencing signal to adjacent cells.

Exploring the functional interactions between geminivirus and host during viral replication, assembly, and movement
TL;DR: Geminivirus replication-associated protein (Rep) is crucial for virus replication and induces differentiated plant cells to reenter the cell cycle to activate the host DNA synthesis machinery by interacting with plant homologs of retinoblastoma proteins as mentioned in this paper .

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.
