Journal ArticleDOI
Complex Formation between Potyvirus VPg and Translation Eukaryotic Initiation Factor 4E Correlates with Virus Infectivity
Simon Léonard,Daniel Plante,Sylvie Wittmann,Nicole Daigneault,Marc G. Fortin,Jean-François Laliberté +5 more
TL;DR: The results suggest that VPg-eIF(iso)4E interaction is a critical element for virus production.
Journal ArticleDOI
Interaction of the viral protein genome linked of turnip mosaic potyvirus with the translational eukaryotic initiation factor (iso) 4E of Arabidopsis thaliana using the yeast two-hybrid system.
TL;DR: The yeast LexA interaction trap was used to screen a cDNA library from Arabidopsis thaliana in order to identify proteins that interact with the viral protein genome linked (VPg)-proteinase of turnip mosaic potyvirus and it was found that eIF(iso)4E plays an essential role in the initiation of the translation of capped mRNAs and its association with VPg would point to a role of the viralprotein in thetranslation of the virus.
Journal ArticleDOI
Cloning, Characterization, and Expression of a cDNA Encoding a 50-Kilodalton Protein Specifically Induced by Cold Acclimation in Wheat
Mario Houde,Jean Danyluk,Jean-François Laliberté,Eric Rassart,Rajinder S. Dhindsa,Fathey Sarhan +5 more
TL;DR: A cold-specific cDNA clone that specifically hybridizes to a major mRNA species of approximately 1650 nucleotides from cold-acclimated wheat that was induced in less than 24 hours of cold treatment and remained at a high steady-state level during the entire period of cold acclimation in the two freezing-tolerant genotypes of wheat tested.
Journal ArticleDOI
Calicivirus translation initiation requires an interaction between VPg and eIF4E
Ian Goodfellow,Yasmin Chaudhry,Ioanna Gioldasi,Andreas Gerondopoulos,Alessandro Natoni,Louisette Labrie,Jean-François Laliberté,Lisa O. Roberts +7 more
TL;DR: This work lends support to the idea that calicivirus VPg acts as a novel ‘cap substitute’ during initiation of translation on virus mRNA.
Journal ArticleDOI
Sequential Recruitment of the Endoplasmic Reticulum and Chloroplasts for Plant Potyvirus Replication
Taiyun Wei,Tyng-Shyan Huang,Tyng-Shyan Huang,Jamie McNeil,Jean-François Laliberté,Jian Hong,Richard S. Nelson,Aiming Wang,Aiming Wang +8 more
TL;DR: Evidence is presented that the 6K-induced vesicles predominantly target chloroplasts, where they amalgamate and induce chloroplast membrane invaginations and suggest that plant potyviruses sequentially recruit the ER and chloroplast for their genome replication.
