StREM1.3 REMORIN Protein Plays an Agonistic Role in Potyvirus Cell-to-Cell Movement in N. benthamiana

Viruses, 2022
REMORIN proteins belong to a plant-specific multigene family that localise in plasma membrane nanodomains and in plasmodesmata. We previously showed that in Nicotiana benthamiana, group 1 StREM1.3 limits the cell-to-cell spread of a potexvirus without ...

Multiple aromatic amino acids are involved in potyvirus movement by forming π-stackings to maintain coat protein accumulation

Phytopathology Research, 2021
Coat protein (CP) is required for potyviruses to move and establish a systemic infection in plants. π-stackings formed by aromatic residues play critical roles in maintaining protein stability and functions.

AlkB RNA demethylase homologues and N 6 ‐methyladenosine are involved in Potyvirus infection

Molecular plant pathology, 2022
Proteins of the alkylation B (AlkB) superfamily show RNA demethylase activity removing methyl adducts from N 6‐methyladenosine (m6A). m6A is a reversible epigenetic mark of RNA that regulates human virus replication but has unclear roles in plant virus ...

Proteolytic Processing of Plant Proteins by Potyvirus NIa Proteases

Journal of Virology, 2021
Viruses are highly adaptive and use multiple molecular mechanisms to highjack or modify the cellular resources to their advantage. They must also counteract or evade host defense responses.

Analysis of proteolytic processing sites in potyvirus polyproteins revealed differential amino acid preferences of NIa-Pro protease in each of seven cleavage sites

PLoS ONE, 2021
Potyviruses encode a large polyprotein that undergoes proteolytic processing, producing 10 mature proteins: P1, HC-Pro, P3, 6K1, CI, 6K2, VPg, NIa-Pro, NIb-RdRp, and CP.

Aphid Transmission of Potyvirus: The Largest Plant-Infecting RNA Virus Genus

Viruses, 2020
Potyviruses are the largest group of plant infecting RNA viruses that cause significant losses in a wide range of crops across the globe. The majority of viruses in the genus Potyvirus are transmitted by aphids in a non-persistent, non-circulative manner

RNA-dependent RNA polymerase (NIb) of the potyviruses is an avirulence factor for the broad-spectrum resistance gene Pvr4 in Capsicum annuum cv. CM334. [PDF]

PLoS ONE, 2015
Potyviruses are one of the most destructive viral pathogens of Solanaceae plants. In Capsicum annuum landrace CM334, a broad-spectrum gene, Pvr4 is known to be involved in resistance against multiple potyviruses, including Pepper mottle virus (PepMoV ...

Effect of disease prevalence and growth stage on symptom severity in the Turnip mosaic virus – Arabidopsis thaliana pathosystem [PDF]

Journal of Plant Protection Research, 2023
In response to stresses, plants are capable of communicating their physiological status to other individuals in the community using several chemical cues. Nearby receivers then adjust their own homeostasis to increase resilience.
