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

Loss of H3.1K27me1 in Arabidopsis confers resistance to Geminivirus by sequestering DNA repair proteins onto rDNA and defense-related genes

TL;DR: Geminiviruses adapt to healthy plants by hijacking its DNA repairing pathways for replication, but the host could retain DNA repairing proteins via sacrificing its genome stability to suppress viral infection.

Molecular Characterization of a Recombinant Isolate of Tomato Leaf Curl New Delhi Virus Associated with Severe Outbreaks in Zucchini Squash in Southern Italy
TL;DR: In this paper , a tomato leaf curl New Delhi virus (ToLCNDV) isolate, denoted to LCNDV-Le, is reported, which contains AV2 and AV1 open reading frames (ORFs) in the virion-sense orientation and five additional ORFs named AC1, AC2, AC3, AC4 and AC5 in the complementary sense orientation.

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.
