Journal ArticleDOI

Jean-Louis Magnard,Aymeric Roccia,Aymeric Roccia,Jean-Claude Caissard,Philippe Vergne,Pulu Sun,Romain Hecquet,Annick Dubois,Laurence Hibrand-Saint Oyant,Frédéric Jullien,Florence Nicolè,Olivier Raymond,Stéphanie Huguet,Raymonde Baltenweck,Sophie Meyer,Patricia Claudel,Julien Jeauffre,Michel Rohmer,Fabrice Foucher,Philippe Hugueney,Mohammed Bendahmane,Sylvie Baudino +21 more
TL;DR: Combining transcriptomic and genetic approaches, it is shown that the Nudix hydrolase RhNUDX1, localized in the cytoplasm, is part of a pathway for the biosynthesis of free monoterpene alcohols that contribute to fragrance in roses.
Journal ArticleDOI
Discovery and functional characterization of two diterpene synthases for sclareol biosynthesis in Salvia sclarea(L.) and their relevance for perfume manufacture
Anne Caniard,Philipp Zerbe,Sylvain Legrand,Allison Cohade,Allison Cohade,Nadine Valot,Nadine Valot,Jean-Louis Magnard,Jean-Louis Magnard,Jörg Bohlmann,Laurent Legendre,Laurent Legendre +11 more
TL;DR: Yeast-based production of sclareol by co-expresssion of SsLPPS and SsSS was efficient enough to warrant the development and use of such technology for the biotechnological production of scareol and other oxygenated diterpenes.
Journal ArticleDOI
Both the adaxial and abaxial epidermal layers of the rose petal emit volatile scent compounds.
Véronique Bergougnoux,Jean-Claude Caissard,Frédéric Jullien,Jean-Louis Magnard,Gabriel Scalliet,J. Mark Cock,Philippe Hugueney,Sylvie Baudino +7 more
TL;DR: It was found that petals represent the major source of scent in R. × hybrida and it was shown that in roses, both epidermal layers are capable of producing and emitting scent volatiles, despite the different morphologies of the cells of these two tissues.
Journal ArticleDOI
One-step identification of conserved miRNAs, their targets, potential transcription factors and effector genes of complete secondary metabolism pathways after 454 pyrosequencing of calyx cDNAs from the Labiate Salvia sclarea L.
Sylvain Legrand,Nadine Valot,Florence Nicolè,Sandrine Moja,Sylvie Baudino,Frédéric Jullien,Jean-Louis Magnard,Jean-Claude Caissard,Laurent Legendre +8 more
TL;DR: This study provides novel genomic information on an angiosperm calyx and an experimental framework to predict in a single step metabolic pathway enzymes and regulator genes including miRNAs.
Journal ArticleDOI
Isolation and functional characterization of a τ-cadinol synthase, a new sesquiterpene synthase from Lavandula angustifolia
Frédéric Jullien,Sandrine Moja,Aurélie Bony,Sylvain Legrand,Sylvain Legrand,Cécile Petit,Tarek Benabdelkader,Tarek Benabdelkader,Kévin Poirot,Sébastien Fiorucci,Yann Guitton,Florence Nicolè,Sylvie Baudino,Jean-Louis Magnard +13 more
TL;DR: Three sTPSs are characterized: a germacrene D (LaGERDS), a (E)-β-caryophyllene (LaCARS) and a τ-cadinol synthase (LaCADS) and the depiction of their active site organization provides evidence of the global influence of the enzymes on the formation of τ- cadinol.
