Geographic distance is more relevant than elevation to patterns of outbreeding in Ranunculus bulbosus

26/12/2013 00:00

Philippe Matter, Chris J. Kettle, Esther R. Frei, Jaboury Ghazou and Andrea R. Pluess Résumé: Mountain ecosystems can exert different selection pressures on plant populations over small scales due to steep environmental gradients. Gene-flow between lower and higher elevation plant...

Organisation et évolution de familles de gènes impliqués dans la maturation du fruit chez le bananier

19/12/2013 00:00

Cyril Jourda Résumé: Les duplications totales du génome (WGD) sont répandues chez les plantes et l'analyse de la séquence du génome du bananier (Musa acuminata ssp. malaccensis, accession DH-Pahang) a identifié trois évènements de WGD chez cette espèce. Pour étudier l'impact de ces...

Emerging Functions of Nodulin-Like Proteins in Non-Nodulating Plant Species

10/12/2013 00:00

Nicolas Denancé, Boris Szurek, Laurent D Noël Résumé: Plant genes whose expression is induced in legumes by Rhizobium bacteria upon nodulation were initially referred to as nodulins. Several of them play a key role in the establishment of symbiosis. Yet, nodulin-like proteins are also found...

Two Evolutionarily Distinct Classes of Paleopolyploidy

01/12/2013 00:00

Olivier Garsmeur, James C Schnable, Ana Almeida, Cyril Jourda, Angélique D’Hont, Michael Freeling Résumé: Whole genome duplications (WGDs) occurred in the distant evolutionary history of many lineages and are particularly frequent in the flowering plant lineages. Following...

Characterization of the terpenoids composition of beers made with the French hop varieties: Strisselspalt, Aramis, Triskel and Bouclier

01/12/2013 00:00

Damien Steyer, Céline Clayeux and Bernadette Laugel Résumé: Among the various compounds brought in to beer by hop, mono- and sesqui- terpenoids are the most studied and contribute to a certain extent to the hoppy aroma of beer. Previous studies have indicated that the concentration of these...

Investigation of glycosyltransferases from oat

31/10/2013 00:00

Thomas Louveau Résumé: Plants produce a diversity of secondary metabolites crucial for their survival into specific ecological niches. Many of these compounds are glycosides generated by the action of family one UDP-dependant glycosyltransferases (UGTs). Glycosylated products of UGTs are...

High phosphate reduces host ability to develop arbuscular mycorrhizal symbiosis without affecting root calcium spiking responses to the fungus

29/10/2013 00:00

Coline Balzergue, Mireille Chabaud, David G. Barker, Guillaume Bécard and Soizic F. Rochange Résumé: The arbuscular mycorrhizal symbiosis associates soil fungi with the roots of the majority of plants species and represents a major source of soil phosphorus acquisition. Mycorrhizal...
