Phenotypes Associated with Down-Regulation of Sl-IAA27 Support Functional Diversity Among Aux/IAA Family Members in Tomato

03/07/2012 00:00

Carole Bassa, Isabelle Mila, Mondher Bouzayen and Corinne Audran-Delalande Résumé: The phytohormone auxin is known to regulate several aspects of plant development, and Aux/IAA transcription factors play a pivotal role in auxin signaling. To extend our understanding of the multiple functions...

CML9, an Arabidopsis calmodulin-like protein, contributes to plant innate immunity through a flagellin-dependent signalling pathway

28/06/2012 00:00

Louis-Jérôme Leba, Cécilia Cheval, Inmaculada Ortiz-Martín, Benoit Ranty, Carmen R. Beuzón, Jean-Philippe Galaud and Didier Aldon Résumé: Many stimuli such as hormones and elicitors induce changes in intracellular calcium levels to integrate information and activate appropriate responses....

Epidermal and cortical roles of NFP and DMI3 in coordinating early steps of nodulation in Medicago truncatula

21/06/2012 00:00

Pauline Rival, Françoise de Billy, Jean-Jacques Bono, Clare Gough, Charles Rosenberg and Sandra Bensmihen Résumé: Legumes have evolved the capacity to form a root nodule symbiosis with soil bacteria called rhizobia. The establishment of this symbiosis involves specific developmental events...

Functional analysis of the N-terminal domain of SPA1

30/05/2012 00:00

Stefan Dieterle Résumé: Plants adapt to their light environment by regulating several key developmental processes like seedling de-etiolation and the transition from vegetative to reproductive growth. Arabidopsis thaliana is a facultative long day flowering plant. It has evolved mechanisms...

The tomato genome sequence provides insights into fleshy fruit evolution

30/05/2012 00:00

The Tomato Genome Consortium (including Pierre Pericard) Résumé: Tomato (Solanum lycopersicum) is a major crop plant and a model system for fruit development. Solanum is one of the largest angiosperm genera1 and includes annual and perennial plants from diverse habitats. Here we present a...

Characterization of a cytochrome P450 monooxygenase gene involved in the biosynthesis of geosmin in Penicillium expansum

23/05/2012 00:00

Muhammad Hussnain Siddique, Thierry Liboz, Nafees Bacha, Olivier Puel, Florence Mathieu and Ahmed Lebrihi Résumé: Geosmin is a terpenoid, an earthy-smelling substance associated with off-flavors in water and wine....

DVC1 (C1orf124) recruits the p97 protein segregase to sites of DNA damage

18/05/2012 00:00

Davis EJ, Lachaud C, Appleton P, Macartney TJ, Näthke I, Rouse J Résumé: Ubiquitin-binding domains (UBDs) are crucial for recruiting many proteins to sites of DNA damage. Here we characterize C1orf124 (Spartan; referred to as DVC1), which has an UBZ4-type UBD found predominantly in DNA...

Fate of polyphenols and antioxidant activity of barley throughout malting and brewing

01/05/2012 00:00

Céline Leitao, Eric Marchioni, Martine Bergaentzlé, Minjie Zhao, Luc Didierjean, Laurence Miesch, Emilie Holder, Michel Miesch and Saïd Ennahar Résumé: Phenolic contents of barley and malt extracts and their corresponding antioxidant activities were investigated using a chromatographic...
