Comparative transcriptome analysis in Triticum aestivum infecting wheat dwarf virus reveals the effects of viral infection on phytohormone and photosynthesis metabolism pathways

Phytopathology Research, 2020
Wheat dwarf virus (WDV), a mastrevirus transmitted by the leafhopper Psammotettix alienus, causes a severe disease in cereal crops. Typical symptoms of wheat plants infected by WDV are yellowing and severe dwarfing.

Survey of Faba Bean («Vicia faba» L.) Virus Diseases in Ethiopia

Phytopathologia Mediterranea, 2007
Surveys conducted in 1996 and 1997 to assess the status of virus diseases affecting faba bean in the major growing areas of Ethiopia indicated that leaf yellowing, rolling, necrosis and stunting were the most common disease symptoms. The highest visually-

Asymmetric interactions between barley yellow dwarf virus -PAV and wheat dwarf virus in wheat

Frontiers in Plant Science, 2023
The deciphering of the epidemiology of a plant virus has long been focused on the study of interactions between partners of one pathosystem. However, plants are exposed to numerous viruses which lead to frequent co-infection scenarios.

Detection and Partial Characterization of Polerovirus and Luteovirus Isolates Associated With Lentil and Chickpea in Ethiopia

Legume Science, Volume 7, Issue 1, March 2025.
ABSTRACT The partial nucleotide sequence of the coat protein (CP) gene of Ethiopian isolates of chickpea chlorotic stunt virus (CpCSV, genus Polerovirus), beet western yellows virus (BWYV, genus Polerovirus), and soybean dwarf virus (SbDV, genus Luteovirus) was determined from lentil and chickpea plants showing yellowing, stunting, and reddening ...

Adaptive evolution by recombination is not associated with increased mutation rates in Maize streak virus

BMC Evolutionary Biology, 2012
Background Single-stranded (ss) DNA viruses in the family Geminiviridae are proving to be very useful in real-time evolution studies. The high mutation rate of geminiviruses and other ssDNA viruses is somewhat mysterious in that their DNA genomes are ...

The Role of a C‐Terminal Seven‐Amino Acid Motif in TbCSV C3 Protein and Its Interaction With NbPOLA2 in Enhancing Viral Replication

Molecular Plant Pathology, Volume 26, Issue 3, March 2025.
A C‐terminal seven‐amino acid motif in C3 protein of tobacco curly shoot virus is essential for viral replication enhancement, recruiting NbPOLA2 to facilitate the viral double‐stranded DNA replication intermediate synthesis. ABSTRACT The C3 protein of tobacco curly shoot virus (TbCSV), a possible evolutionary intermediate between truly monopartite ...

Characterisation of a Betasatellite Associated With Tomato Yellow Leaf Curl Guangdong Virus and Discovery of an Unusual Modulation of Virus Infection Associated With C4 Protein

Molecular Plant Pathology, Volume 26, Issue 1, January 2025.
The C4 protein, encoded by tomato yellow leaf curl Guangdong virus (TYLCGdV), does not inhibit PTGS or TGS; the C4 protein modulates TYLCGdV infection by regulating the cytosine methylation level of viral genome at different infection stages. ABSTRACT Tomato yellow leaf curl Guangdong virus (TYLCGdV), a monopartite begomovirus first identified in 2004,

Network Analysis of the Papaya Orchard Virome from Two Agroecological Regions of Chiapas, Mexico

mSystems, 2020
The study of complex ecological interactions, such as those among host, pathogen, and vector communities, can help to explain host ranges and the emergence of novel pathogens. We evaluated the viromes of papaya orchards, including weed and insect viromes,

Two mutations in the truncated Rep gene RBR domain delayed the Wheat dwarf virus infection in transgenic barley plants

Journal of Integrative Agriculture, 2018
Wheat dwarf virus (WDV), an important cereal pathogen, is closely related to Maize streak virus (MSV), a model virus of the Mastrevirus genus. Based on its similarity to known MSV resistance strategies, a truncated part of the WDV replication-associated (
