Journal ArticleDOI
Systemic acquired silencing: transgene-specific post-transcriptional silencing is transmitted by grafting from silenced stocks to non-silenced scions.
TL;DR: Results suggest that a non‐metabolic, transgene‐specific, diffusable messenger mediates the propagation of de novo post‐transcriptional silencing through the plant.
Journal ArticleDOI
Transgene-induced gene silencing in plants.
Hervé Vaucheret,Christophe Béclin,Taline Elmayan,Frank Feuerbach,Christian Godon,Jean-Benoit Morel,Philippe Mourrain,Jean-Christophe Palauqui,Samantha Vernhettes +8 more
TL;DR: A review of transgene-induced silencing phenomena in plants and the involvement of RNA was hypothesized to explain post-transcriptional silencing in plants, fungi and nematodes.
Journal ArticleDOI
High-Resolution Whole-Mount Imaging of Three-Dimensional Tissue Organization and Gene Expression Enables the Study of Phloem Development and Structure in Arabidopsis
Elisabeth Truernit,Hélène Bauby,Bertrand Dubreucq,Olivier Grandjean,John Runions,Julien Barthélémy,Jean-Christophe Palauqui +6 more
TL;DR: A staining technique that can be used to image entire plant organs using confocal laser scanning microscopy and produces high-resolution images that allow three-dimensional reconstruction of the cellular organization of plant organs, which significantly improves the speed and accuracy of the investigation of plant growth and development.
Journal ArticleDOI
Arabidopsis Mutants Impaired in Cosuppression
Taline Elmayan,Sandrine Balzergue,Fabrice Béon,Violaine Bourdon,Jérémy Daubremet,Yvette Guénet,Philippe Mourrain,Jean-Christophe Palauqui,Samantha Vernhettes,Tiphaine Vialle,Katia Wostrikoff,Hervé Vaucheret +11 more
TL;DR: The results indicate that sgs mutations act in trans to impede specifically transgene-induced post-transcriptional gene silencing.
Journal ArticleDOI
Infection of tobacco or arabidopsis plants by cmv counteracts systemic post-transcriptional silencing of nonviral (trans)genes
TL;DR: Models are proposed to explain how CMV can inhibit cellular factors involved in the RNA degradation step of PTGS and/or inhibit the systemic spread of the silencing signal to tissues emerging from the meristem.
