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

TL;DR: A two-T DNA vector carrying a hairpin of the intergenic region of Ageratum yellow vein virus residing in an intron inserted in an untranslatable nucleocapsid protein (NP) fragment of Melon yellow spot virus indicates that MYSV resistance is mediated through post-transcriptional gene silencing.

An insight into plant–Tomato leaf curl New Delhi virus interaction
Namisha Sharma,Manoj Prasad +1 more
TL;DR: A comprehensive overview of Tomato leaf curl New Delhi virus (ToLCNDV), a member of family Geminiviridae and the plant defense system initiated against this virus and the evaluation of To LCNDV infection in a variety of hosts differing in their tolerance and identification of differentially expressed genes would be helpful in speculating the threats associated with similar begomoviral invasions.

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.
