Journal ArticleDOI
An m6A-YTH Module Controls Developmental Timing and Morphogenesis in Arabidopsis
Laura Arribas-Hernández,Simon Bressendorff,Mathias Henning Hansen,Christian Peter Poulsen,Susanne Erdmann,Peter Brodersen +5 more
TL;DR: The relevance of a cytoplasmic m6A-YTH regulatory module in the timing and execution of plant organogenesis is established and the role of YT521-B homology domain proteins is established.
Journal ArticleDOI
Lessons on RNA Silencing Mechanisms in Plants from Eukaryotic Argonaute Structures
TL;DR: The parallel analysis of AGO structures and plant AGO mutations suggests that such interactions with GW proteins may be a determinant of whether an endonucleolytically competent RISC is formed.
Journal ArticleDOI
COP1 E3 ligase protects HYL1 to retain microRNA biogenesis
TL;DR: It is shown that the cytoplasmic partitioning of COP1 under light is essential to protectHYL1 against protease X, and a novel regulatory network involving HYL1, proteaseX, COP1 and light signalling that is indispensable for miRNA biogenesis in Arabidopsis thaliana is suggested.
Journal ArticleDOI
ARAD proteins associated with pectic Arabinan biosynthesis form complexes when transiently overexpressed in planta
Jesper Harholt,Jacob Krüger Jensen,Jacob Krüger Jensen,Yves Verhertbruggen,Yves Verhertbruggen,Casper Søgaard,Sophie Bernard,Majse Nafisi,Christian Peter Poulsen,Naomi Geshi,Yumiko Sakuragi,Azeddine Driouich,J. Paul Knox,Henrik Vibe Scheller,Henrik Vibe Scheller,Henrik Vibe Scheller +15 more
TL;DR: Data show that ARAD2 is associated with arabinan biosynthesis, not redundant with ARAD1, and that the two glycosyltransferases may function in complexes held together by disulfide bridges.
Journal ArticleDOI
A β-glucuronosyltransferase from Arabidopsis thaliana involved in biosynthesis of type II arabinogalactan has a role in cell elongation during seedling growth.
Eva Knoch,Adiphol Dilokpimol,Theodora Tryfona,Christian Peter Poulsen,Guangyan Xiong,Jesper Harholt,Bent O. Petersen,Peter Ulvskov,Masood Z. Hadi,Toshihisa Kotake,Yoichi Tsumuraya,Markus Pauly,Paul Dupree,Naomi Geshi +13 more
TL;DR: A role for the glucuronosyltransferase in the biosynthesis of type II AG, with a biological role during seedling growth, is discussed, and a reduction of GlcA substitution on Gal-β-1,6-Gal and β- 1,3-Gal is revealed, indicating an in vivo role of AtGlcAT14A in synthesis of those structures in type-II AG.
