Dr. Éva Várallyay - MATE Research
Overview
Dr. Éva Várallyay is interested in diagnostics improvement and basic research in plant virology, and plant microbiome research. In her group they use high-throughput sequencing for virome and metagenome analyses of plant pathogens in grapevine, fruit trees and weeds neighbouring crop fields. Based on her previous experience in RNAi research she investigates possible antiviral silencing suppressor activity of the recently described uncharacterized viruses and gene-expression changes of the miRNA pattern in the pathogen infected plants. In their group they investigate multiple infection on woody plants and possible virus reservoir role of weeds growing at the edges of crop fields.

Projects
Effect of multiple virus infection on the antiviral RNA interference in perennial woody hosts (grapevine and fruit trees); National Research, Development and Innovation Office K134895; (2020-2025 Principal Investigator)
Perennial woody plants can be infected with several viruses and viroids. During their multiple infection symptoms strengthens and will affect the quality and quantity of the fruit. In this project try uncover viral strategies how universally or uniquely they supress the defence reaction of the host.
Identification and investigation of berry fruit infecting viruses using HTS based methods; Croatian-Hungarian TET Bilateral; National Research, Development and Innovation Office 2019-2.1.11-TÉT-2020-00124; (2021-2024 Principal Investigator)
Berry fruit plants can be infected by several viruses. In this we compare raspberry and grapevine infecting RBDV originating from Slovenia and Hungary, characterize different isolates. Viromes of raspberries showing virus like symptoms will be determined using HTS.
New approaches of virus elimination from grapevine: examination the applicability of chemotherapy and induced resistance; National Research, Development and Innovation Office K131679; (2019-2024 participant)
Virus diseases of grapevine alone or in mixed infection cannot be efficiently controlled at the vineyard. New, chemotherapy base methods used during virus elimination can speed up the previous meristem preparation-based process and help to improve the quality of the propagation material.
Investigation of plant pathogens causing decline in fruit tree plantations by molecular biology methods; National Research, Development and Innovation Office K127951; (2018-2023 Principal Investigator)
Using cutting edge new HTS based metagenomics studies we investigate the composition of pathogen complexes in fruit trees at declining orchards and describe molecular mechanism which changes lead to development of symptoms and decline of the plantation.
