Enhanced vestibular-evoked balance responses in adolescents with idiopathic scoliosis

Jean-Philippe Cyr, Roxane Crépin, Pierre Mercier, Jean‐Sébastien Blouin et autres

We tested the hypothesis that adolescent idiopathic scoliosis (AIS) patients exhibit asymmetries in the vestibular control of balance. We observed larger vestibular-evoked balance responses in participants with AIS to stimuli targeting primary vestibular afferents unilaterally and bilaterally. These larger balance-correcting responses of …

R-loop control and mitochondrial genome stability require the 5′-3′ exonuclease/flap endonuclease OEX1

Déborah Schatz, Anaïs Le Blevenec, Fabio Moratti, Kin Pan Chung et autres

Maintenance of the plant organelle genomes involves factors mostly inherited from their symbiotic ancestors. In bacteria, DNA polymerase I (Pol I) performs multiple replication and repair functions through its 5'-3'-exonuclease/flap-endonuclease domain. Plant organelles possess 2 DNA polymerases that are evolutionarily derived from …

The BRAHMA-associated SWI/SNF chromatin remodeling complex controls Arabidopsis seed quality and physiology

Magdalena Wrona, Julia Zinsmeister, Michał Krzysztoń, Claire Villette et autres

The SWI/SNF (SWItch/Sucrose Non-Fermentable) chromatin remodeling complex is involved in various aspects of plant development and stress responses. Here, we investigated the role of BRM (BRAHMA), a core catalytic subunit of the SWI/SNF complex, in Arabidopsis thaliana seed biology. brm-3 seeds exhibited …

R-Loop control and mitochondria genome stability require the 5’-3’ exonuclease/flap endonuclease OEX1

Déborah Schatz-Daas, Anaïs Le Blevenec, Fabio Moratti, Pierre Mercier et autres

Abstract Maintenance of the plant organelle genomes involves factors mostly inherited from their bacterial symbiotic ancestors. In bacteria, a major player in genome maintenance is DNA Polymerase I (Pol I), which provides a 5’-3’-exonuclease/flap-endonuclease activity required for multiple replication and repair functions. …

Characterization of Subcellular Dynamics of Sterol Methyltransferases Clarifies Defective Cell Division in smt2 smt3, a C-24 Ethyl Sterol-Deficient Mutant of Arabidopsis

Daisaku Ohta, Ayaka Fuwa, Yuka Yamaroku, Kazuki Isobe et autres

An Arabidopsis sterol mutant, smt2 smt3, defective in sterolmethyltransferase2 (SMT2), exhibits severe growth abnormalities. The loss of C-24 ethyl sterols, maintaining the biosynthesis of C-24 methyl sterols and brassinosteroids, suggests specific roles of C-24 ethyl sterols. We characterized the subcellular localizations of …

Methyl-Jasmonate Functions as a Molecular Switch Promoting Cross-Talk between Pathways for the Biosynthesis of Isoprenoid Backbones Used to Modify Proteins in Plants

Quentin Chevalier, Alexandre Huchelmann, Pauline Debié, Pierre Mercier et autres

In plants, the plastidial mevalonate (MVA)-independent pathway is required for the modification with geranylgeranyl groups of CaaL-motif proteins, which are substrates of protein geranylgeranyltransferase type-I (PGGT-I). As a consequence, fosmidomycin, a specific inhibitor of 1-deoxy-d-xylulose (DX)-5 phosphate reductoisomerase/DXR, the second enzyme in …

Methyl-Jasmonate Functions as a Molecular Switch Promoting Cross-Talk between Pathways for the Biosynthesis of Isoprenoid Backbones Used to Modify Proteins in Plants

Quentin Chevalier, Alexandre Huchelmann, Pauline Debié, Pierre Mercier et autres

The modification of GFP-CaaL sensor proteins by geranylgeranyl groups in plants requires an active plastidial mevalonate (MVA)-independent pathway. As a consequence, fosmidomycin, a specific inhibitor of 1-deoxy-D-xylulose (DX)-5 phosphate reductoisomerase/DXR, the second enzyme in this so-called methylerythritol phosphate (MEP) pathway, impedes protein …

Neural control of the trunk during back extension and rotation in adolescents with and without idiopathic scoliosis : preliminary results

Jean-Philippe Cyr, Sahian Alicia Maldonado Numata, Amirreza Kebritchi, Patricia Larouche et autres

Scoliosis is a three-dimensional deformation of the spine consisting of lateral deviation and rotation of the vertebrae. It often occurs and develops in adolescence, which can have psychological and physiological consequences, or require spinal instrumentation surgery. The etiology of adolescent idiopathic scoliosis …

The Arabidopsis thaliana–Streptomyces Interaction Is Controlled by the Metabolic Status of the Holobiont

Stéfanie Graindorge, Claire Villette, Sandrine Koechler, Chloé Groh et autres

How specific interactions between plant and pathogenic, commensal, or mutualistic microorganisms are mediated and how bacteria are selected by a plant are important questions to address. Here, an Arabidopsis thaliana mutant called chs5 partially deficient in the biogenesis of isoprenoid precursors was …
