Journal ArticleDOI
The Polerovirus F Box Protein P0 Targets ARGONAUTE1 to Suppress RNA Silencing
Diane Bortolamiol,Maghsoud Pazhouhandeh,Katia Marrocco,Pascal Genschik,Véronique Ziegler-Graff +4 more
TL;DR: The molecular mechanism by which P0 impairs PTGS is investigated and it is proposed that P0 hijacks the host SCF machinery to modulate gene silencing by destabilizing AGO1.
Journal ArticleDOI
F-box-like domain in the polerovirus protein P0 is required for silencing suppressor function
Maghsoud Pazhouhandeh,Monika Dieterle,Katia Marrocco,Esther Lechner,Bassam Berry,Véronique Brault,Odile Hemmer,Thomas Kretsch,Kenneth Richards,Pascal Genschik,Véronique Ziegler-Graff +10 more
TL;DR: A model in which P0 of two Arabidopsis-infecting poleroviruses interacts by means of a conserved minimal F-box motif withArabidopsis thaliana orthologs of S-phase kinase-related protein 1 (SKP1), a component of the SCF family of ubiquitin E3 ligases is supported.
Journal ArticleDOI
Degradation of the antiviral component ARGONAUTE1 by the autophagy pathway
Benoît Derrien,Nicolas Baumberger,Mikhail Schepetilnikov,Corrado Viotti,Julia De Cillia,Véronique Ziegler-Graff,Erika Isono,Karin Schumacher,Pascal Genschik +8 more
TL;DR: The results demonstrate that a selective process such as ubiquitylation can lead to the degradation of a key regulatory protein such as AGO1 by a degradation process generally believed to be unspecific.
Journal ArticleDOI
P0 of beet Western yellows virus is a suppressor of posttranscriptional gene silencing.
Sébastien Pfeffer,Patrice Dunoyer,F. Heim,Kenneth Richards,Gérard Jonard,Véronique Ziegler-Graff +5 more
TL;DR: It is shown that P0 of beet western yellows virus (BWYV) displays strong silencing suppressor activity in a transient expression assay based upon its ability to inhibit PTGS of green fluorescent protein (GFP) when expressed in agro-infiltrated leaves of Nicotiana benthamiana containing a GFP transgene.
Journal ArticleDOI
Aphid transmission of beet western yellows luteovirus requires the minor capsid read-through protein p74
V. Brault,J.F.J.M. van den Heuvel,Martin Verbeek,Véronique Ziegler-Graff,A. Reutenauer,E. Herrbach,J.C. Garaud,Hubert Guilley,Kenneth Richards,Gérard Jonard +9 more
TL;DR: Beet western yellows virus carrying various mutations in the read‐through domain was tested for its ability to be transmitted to test plants by aphids fed on agro‐infected plants and semi‐purified or purified virus preparations and it is established that the read-through domain carries determinants that are essential for aphid transmission.
