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

Rock paper scissors: CRISPR/Cas9-mediated interference with geminiviruses in plants.
TL;DR: Studies on the clustered regularly interspaced short palindromic repeat and its associated systems (CRISPR/Cas) and its applications in defense against viruses in a number of model plants have been intensively carried out, shedding light on the potential use of CRISpr/Casmediated anti-geminivirus strategy in the future.

TL;DR: The results showed that in the inoculated plants OELCuV alone can cause downward curling and yellowing of leaves with thickened veins, however, when co-inoculated with the non-cognate CLCuMuB it could functionally trans-replicate CLCUMuB resulting in a more severe phenotype.

TL;DR: It is found that S162 and S165 of Chinese wheat mosaic virus (CWMV) cysteine-rich protein (CRP) are phosphorylated by SAPK7 and play key roles in CWMV infection.

Identification, molecular characterization and relative incidence of begomoviruses infecting bean crops in northwestern Argentina: an update
Gonzalo Matías Varela,Vera Avalos,Pablo Gastón Reyna,Pablo Gastón Reyna,Irma Graciela Laguna,Patricia Rodriguez Pardina +5 more
TL;DR: The incidence of the three previously characterized begomoviruses (BGMV, SbBMV and ToYSV) was assessed, and BGMV was found to exhibit the highest incidence.
Journal ArticleDOI
Recombinant Tomato leaf curl New Delhi virus is associated with yellow vein mosaic disease of okra in India
TL;DR: Phylogenetic and recombination analysis indicated that both DNA A and DNA B components of ToLCNDV infecting okra has the recombinant origin from BYVMV, To LCNDV, and SLCCNV as the foremost parents.

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.
