Journal ArticleDOI
An antagonistic function for Arabidopsis DCL2 in development and a new function for DCL4 in generating viral siRNAs
TL;DR: It is shown that viral siRNAs are produced by D CL4, and that DCL2 can substitute for DCL4 when this latter activity is reduced or inhibited by viruses, pointing to the competitiveness of DCL1.
Journal ArticleDOI
DRB4-dependent TAS3 trans-acting siRNAs control leaf morphology through AGO7.
Xavier Adenot,Taline Elmayan,Dominique Lauressergues,Stéphanie Boutet,Nicolas Bouché,Virginie Gasciolli,Hervé Vaucheret +6 more
TL;DR: Results indicate that the dsRNA binding protein DRB4 is required for proper ta-siRNA production, presumably by interacting with DCL4, an interaction analogous to that of HYL1 with D CL1 during miRNA production , and that TAS3 ta-SIRNAs are required for Proper leaf development through the action of AGO7/ZIPPY.
Journal ArticleDOI
Primary transcripts of microRNAs encode regulatory peptides
Dominique Lauressergues,Jean-Malo Couzigou,Hélène San Clemente,Yves Martinez,Christophe Dunand,Guillaume Bécard,Jean-Philippe Combier +6 more
TL;DR: It is shown that plant pri-miRNAs contain short open reading frame sequences that encode regulatory peptides, suggesting that miPEPs are widespread throughout the plant kingdom and might have agronomical applications.
Journal ArticleDOI
Arabidopsis FIERY1, XRN2, and XRN3 are endogenous RNA silencing suppressors.
Isabelle Gy,Virginie Gasciolli,Dominique Lauressergues,Jean-Benoit Morel,Julie Gombert,Florence Proux,Caroline Proux,Hervé Vaucheret,Allison C. Mallory +8 more
TL;DR: It is shown that the nuclear exoribonucleases XRN2 and XRN3 are endogenous PTGS suppressors, and excised MIRNA loops are identified as templates for X RN2 andXRN3 and show that X RN3 is critical for proper development.
Journal ArticleDOI

TL;DR: Molecular evidence is used to ask how the current pattern of plant species with NFN symbiosis evolved and to suggest that this symbiosis is subject to an underestimated adverse selection pressure.
