Journal ArticleDOI
In Posidonia oceanica cadmium induces changes in DNA methylation and chromatin patterning
TL;DR: The data demonstrate that Cd perturbs the DNA methylation status through the involvement of a specific methyltransferase, linked to nuclear chromatin reconfiguration likely to establish a new balance of expressed/repressed chromatin.
Journal ArticleDOI
The elongata mutants identify a functional Elongator complex in plants with a role in cell proliferation during organ growth
Hilde Nelissen,Delphine Fleury,Leonardo Bruno,Pedro Robles,Lieven De Veylder,Jan Traas,José Luis Micol,Marc Van Montagu,Dirk Inzé,Mieke Van Lijsebettens +9 more
TL;DR: Morphological and molecular phenotypes show that the ELONGATA (ELO) genes function in the same biological process and the epistatic interactions between the ELO genes can be explained by the model of complex formation in yeast.
Journal ArticleDOI
Plant Elongator regulates auxin-related genes during RNA polymerase II transcription elongation
Hilde Nelissen,Steven De Groeve,Delphine Fleury,Delphine Fleury,Pia Neyt,Leonardo Bruno,Maria Beatrice Bitonti,Filip Vandenbussche,Dominique Van Der Straeten,Takahiro Yamaguchi,Takahiro Yamaguchi,Hirokazu Tsukaya,Hirokazu Tsukaya,Erwin Witters,Geert De Jaeger,Andreas Houben,Mieke Van Lijsebettens +16 more
TL;DR: Although the structure of Elongator and its substrate are conserved, target gene selection has diverged, showing that auxin signaling and influx are under chromatin control.
Journal ArticleDOI
Localization of ascorbic acid, ascorbic acid oxidase, and glutathione in roots of Cucurbita maxima L.
R. Liso,Mario C. De Tullio,Samantha Ciraci,Raffaella Balestrini,Nicoletta La Rocca,Leonardo Bruno,Adriana Chiappetta,Maria Beatrice Bitonti,Paola Bonfante,Oreste Arrigoni +9 more
TL;DR: The different pattern of distribution of ASC in different tissues and cell compartments reflects its possible role in cell metabolism and root morphogenesis.
Journal ArticleDOI
Histone H2B monoubiquitination is required to reach maximal transcript levels of circadian clock genes in Arabidopsis.
Kristiina Himanen,Magdalena Woloszynska,Tommaso Matteo Boccardi,Steven De Groeve,Hilde Nelissen,Leonardo Bruno,Marnik Vuylsteke,Mieke Van Lijsebettens +7 more
TL;DR: The hub1-1 mutation reduced the amplitudes of a number of induced clock gene expression peaks, as well as the HUB1-mediated histone H2BUb and H3K4Me3 marks associated with the coding regions, suggesting a role for HUB 1 in facilitating transcriptional elongation in plants.
