Identification and estimation of sequence variation dynamics of Tomato Leaf curl Palampur virus and betasatellite complex infecting a new weed host

Muhammad Naeem Sattar, +3 more
TL;DR: In this paper , the authors used pairwise nucleotide (nt) sequence comparison and phylogenetic studies of the inferred genome sequences confirmed the identity of a bipartite begomovirus Tomato leaf curl Palampur virus (ToLCPalV) in the symptomatic Solanum nigrum plants showing curling on leaf margins, leaf chlorosis, leaf crumpling and stunting in growth.

Molecular characterization and infectivity analysis of tomato leaf curl New Delhi virus isolates infecting potato

A. Jeevalatha, +7 more
TL;DR: Chakrabarti et al. as discussed by the authors determined the DNA sequence of complete genome of a new isolate (KAN-6) of tomato leaf curl New Delhi virus (ToLCNDV) from Kanpur, Uttar Pradesh, India was determined Sequence analysis indicated that it shared maximum identity to ToLNDV isolates from pumpkin and ashgourd.

Diverse begomovirus-betasatellite complexes cause tomato leaf curl disease in the western India

Sangeeta, +9 more
- 20 Feb 2023 - 
TL;DR: In this article , the authors reported the identification of a complex of begomoviruses including 19 DNA-A and 4 DNA-B as well as 15 betasatellites with ToLCD in the western part of the country.

Effects of the transient expression of heterologous RNA virus-encoded silencing suppressors on the infectivity and systemic movement of tomato leaf curl New Delhi virus

Zafar Iqbal, +4 more
- 01 Sep 2020 - 
TL;DR: Results show that heterologous RSSs may enhance ToLCNDV pathogenicity and are consistent with the idea that geminivirus movement in plants is constrained by an RNAi-based resistance.

Possible emergence of new geminiviruses by frequent recombination.

Malla Padidam, +2 more
- 20 Dec 1999 - 
TL;DR: Geminiviruses are a group of plant viruses characterized by a genome of circular single-stranded DNA encapsidated in twinned quasi-isometric particles and recombination is very frequent and occurs between species and within and across genera.

Rates of evolutionary change in viruses: patterns and determinants.

Siobain Duffy, +3 more
- 04 Mar 2008 - 
TL;DR: It is shown that the high rate of nucleotide substitution in RNA viruses is matched by some DNA viruses, suggesting that evolutionary rates in viruses are explained by diverse aspects of viral biology, such as genomic architecture and replication speed, and not simply by polymerase fidelity.

RNA-based antiviral immunity

Shou-Wei Ding
- 01 Sep 2010 - 
TL;DR: Recent studies on the features of viral siRNAs and other virus-derived small RNAs from virus-infected fungi, plants, insects, nematodes and vertebrates are reviewed and the innate and adaptive properties of RNA-based antiviral immunity are discussed.

Emerging Virus Diseases Transmitted by Whiteflies

Jesús Navas-Castillo, +2 more
- 12 Aug 2011 - 
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.

Cross-Species Virus Transmission and the Emergence of New Epidemic Diseases

Colin R. Parrish, +8 more
- 01 Sep 2008 - 
TL;DR: What is known about host switching leading to viral emergence from known examples is reviewed, considering the evolutionary mechanisms, virus-host interactions, host range barriers to infection, and processes that allow efficient host-to-host transmission in the new host population.
