Consensus mapping of major resistance genes and independent QTL for quantitative resistance to sunflower downy mildew

09/01/2012 00:00
Vincourt P, As-Sadi F, Bordat A, Langlade NB, Gouzy J, Pouilly N, Lippi Y, Serre F, Godiard L, Tourvieille de Labrouhe D and Vear F.   Abstract: Major gene resistance to sunflower downy mildew (Plasmopara halstedii) races 304 and 314 was found to segregate independently from the resistance to races 334, 307 and 304 determined by the gene Pl2, already positioned on Linkage Group (LG) 8 of sunflower molecular maps. Using a consensus SSR–SNP map constructed from the INEDI RIL population and a...

14-3-3-regulated Ca(2+)-dependent protein kinase CPK3 is required for sphingolipid-induced cell death in Arabidopsis

08/31/2012 00:00
C Lachaud, E Prigent, P Thuleau, S Grat, D Da Silva, C Brière, C Mazars and V Cotelle   Abstract: In eukaryotic cells, sphingoid long chain bases (LCBs) such as sphingosine or phytosphingosine (PHS) behave as second messengers involved in various processes including programmed cell death (PCD). In plants, induction of PCD by LCBs has now been described, but the signalling pathway is still enigmatic. Using Arabidopsis, we identify new key steps in this pathway. We demonstrate that PHS...

Patterns of genetic variation across altitude in three plant species of semi-dry grasslands

08/01/2012 00:00
Hahn T, Kettle CJ, Ghazoul J, Frei ER, Matter P, Pluess AR.   Abstract: Environmental gradients caused by altitudinal gradients may affect genetic variation within and among plant populations and inbreeding within populations. Populations in the upper range periphery of a species may be important source populations for range shifts to higher altitude in response to climate change. In this study we investigate patterns of population genetic variation at upper peripheral and lower more...

Saccharothrix algeriensis NRRL B-24137 : proprietés de biocontrole, colonisation et résistance systemique induite contre Botrytis cinerea sur la vigne et Arabidopsis thaliana

07/13/2012 00:00
Saima Muzammil   Abstract: Au cours de cette thèse, un isolat de sol de désert, Saccharothrix algeriensis NRRL B-24137, a été évalué pour ses propriétés bioactives contre le champignon phytopathogène Botrytis cinerea, pour sa colonization sur Vitis vinifera L., et Arabidopsis thaliana ainsi qu’en vue d’étudier les méchanismes de résistance systémique induite (ISR) contre B. cinerea. Les résultats obtenus nous ont permis premièrement de montrer que Sa. algeriensis NRRL B-24137 peut...

The banana (Musa acuminata) genome and the evolution of monocotyledonous plants

Angélique D’Hont, France Denoeud, Jean-Marc Aury, Franc-Christophe Baurens, Françoise Carreel, Olivier Garsmeur, Benjamin Noel, Stéphanie Bocs, Gaëtan Droc, Mathieu Rouard, Corinne Da Silva, Kamel Jabbari, Céline Cardi, Julie Poulain, Marlène Souquet, Karine Labadie, Cyril Jourda, Juliette Lengellé, Marguerite Rodier-Goud, Adriana Alberti, Maria Bernard, Margot Correa, Saravanaraj Ayyampalayam, Michael R Mckain, Jim Leebens-Mack, Diane Burgess, Mike Freeling, Didier Mbéguié-A-Mbéguié, Matthieu...

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

07/03/2012 00:00
Carole Bassa, Isabelle Mila, Mondher Bouzayen and Corinne Audran-Delalande   Abstract: 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 of Aux/IAAs further, the present study describes the functional characterization of Sl-IAA27, a member of the tomato Aux/IAA gene family. Sl-IAA27 displays a distinct behavior compared with most...

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

06/28/2012 00:00
Louis-Jérôme Leba, Cécilia Cheval, Inmaculada Ortiz-Martín, Benoit Ranty, Carmen R. Beuzón, Jean-Philippe Galaud and Didier Aldon   Abstract: Many stimuli such as hormones and elicitors induce changes in intracellular calcium levels to integrate information and activate appropriate responses. The Ca2+ signals are perceived by various Ca2+ sensors, and calmodulin (CaM) is one of the best characterized in eukaryotes. Calmodulin-like (CML) proteins extend the Ca2+ toolkit in plants; they...

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

06/21/2012 00:00
Pauline Rival, Françoise de Billy, Jean-Jacques Bono, Clare Gough, Charles Rosenberg and Sandra Bensmihen   Abstract: 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 occurring both in the root epidermis (notably bacterial entry) and at a distance in the underlying root cortical cells (notably cell divisions leading to nodule organogenesis). The processes of...

Functional analysis of the N-terminal domain of SPA1

05/30/2012 00:00
Stefan Dieterle   Abstract: 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 to time its flowering according to seasonal and environmental cues. There are several signaling pathways for flowering time control that can be distinguished by the environmental or developmental...

The tomato genome sequence provides insights into fleshy fruit evolution

05/30/2012 00:00
The Tomato Genome Consortium (including Pierre Pericard)   Abstract: 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 high-quality genome sequence of domesticated tomato, a draft sequence of its closest wild relative, Solanum pimpinellifolium2, and compare them to each other and to the potato genome (Solanum...
