Detection of Apple Hammerhead Viroid, Apple Luteovirus 1 and Citrus Concave Gum-Associated Virus in Apple Propagation Materials and Orchards in the Czech Republic and Hungary

Viruses, 2022
Grafting cultivars onto rootstocks is a widely used practice by the apple industry predominantly aimed at faster fruit bearing. Using high-throughput sequencing, we revealed the presence of recently described viral agents, namely apple hammerhead viroid (

The Coat Protein Is Dispensable for the Establishment of Systemic Infections by Pea Enation Mosaic Enamovirus

Molecular Plant-Microbe Interactions, 1997
Deletions in the coat protein (CP) open reading frame (ORF)-3 of pea enation mosaic enamovirus (PEMV) did not inhibit the systemic movement of PEMV. As early as 48 h postinoculation, truncated viral RNAs were detected in the roots and uninoculated leaves

Effects of Barley Yellow Dwarf Virus on Yield and Yield Components in Different Winter Wheat Genotypes

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Agriculture, 2020
Barley Yellow Dwarf Virus is a Luteovirus disease that affects small grain yields. The climatic conditions of the agricultural year favoured the development of vectors, so that the virus attack caused significant damage on different genotypes.

Development of a Novel Tissue Blot Hybridization Chain Reaction for the Identification of Plant Viruses

Plants, 2022
Assays for the high throughput screening of crops for virus monitoring need to be quick, easy, and low cost. One method involves using tissue blot immunoassays (TBIA), where plant stems are blotted onto nitrocellulose membrane and screened with available

Viromes of Hungarian Peach Trees Identified by High-Throughput Sequencing of Small RNAs

Plants, 2022
Peach trees can be infected with viruses and viroids. As we do not have efficient plant protection methods against these pathogens, the prevention of infection is crucial. Fruit trees are maintained by vegetative propagation.
