The Brassicaceae-Specific EWR1 Gene Provides Resistance to Vascular Wilt Pathogens

05/02/2014 00:00

Koste A. Yadeta, Dirk-Jan Valkenburg, Mathieu Hanemian, Yves Marco and Bart P. H. J. Thomma Résumé: Soil-borne vascular wilt diseases caused by Verticillium spp. are among the most destructive diseases worldwide in a wide range of plant species. The most effective means of controlling...

Triterpene Biosynthesis in Plants

29/01/2014 00:00

Ramesha Thimmappa, Katrin Geisler, Thomas Louveau, Paul O'Maille, and Anne Osbourn Résumé: The triterpenes are one of the most numerous and diverse groups of plant natural products. They are complex molecules that are, for the most part, beyond the reach of chemical synthesis. Simple...

Nitric oxide-triggered remodeling of chloroplast bioenergetics and thylakoid proteins upon nitrogen starvation in Chlamydomonas reinhardtii

28/01/2014 00:00

Wei L, Derrien B, Gautier A, Houille-Vernes L, Boulouis A, Saint-Marcoux D, Malnoë A, Rappaport F, de Vitry C, Vallon O, Choquet Y, Wollman FA. Résumé: Starving microalgae for nitrogen sources is commonly used as a biotechnological tool to boost storage of reduced carbon into starch granules...

Thylakoid FtsH protease contributes to photosystem II and cytochrome b6f remodeling in Chlamydomonas reinhardtii under stress conditions

21/01/2014 00:00

Malnoë A, Wang F, Girard-Bascou J, Wollman FA, de Vitry C Résumé: FtsH is the major thylakoid membrane protease found in organisms performing oxygenic photosynthesis. Here, we show that FtsH from Chlamydomonas reinhardtii forms heterooligomers comprising two subunits, FtsH1 and FtsH2. We...

The NF-YC1 interacting protein SIN1, a member of the GRAS family, is required for nodule organogenesis, infection thread progression and lateral root growth

14/01/2014 00:00

Marina Battaglia, Carolina Rípodas, Joaquín Clúa, Maël Baudin, O. Mario Aguilar, Andreas Niebel, María Eugenia Zanetti and Flavio Antonio Blanco Résumé: A C subunit of the heterotrimeric nuclear factor Y (NF-YC1) was shown to play a key role in nodule organogenesis and bacterial infection...

Genome-wide identification, phylogenetic analysis, expression profiling, and protein–protein interaction properties of TOPLESS gene family members in tomato

07/01/2014 00:00

Yanwei Hao, Xinyu Wang, Xian Li, Carole Bassa, Isabelle Mila, Corinne Audran, Elie Maza, Zhengguo Li, Mondher Bouzayen, Benoit van der Rest and Mohamed Zouine Résumé: Members of the TOPLESS gene family emerged recently as key players in gene repression in several mechanisms, especially in...

The Saharan isolate Saccharothrix algeriensis NRRL B-24137 induces systemic resistance in Arabidopsis thaliana seedlings against Botrytis cinerea

01/01/2014 00:00

Saima Muzammil, Clotilde Graillon, Rayenne Saria, Florence Mathieu, Ahmed Lebrihi and Stéphane Compant Résumé: Saccharothrix algeriensis NRRL B-24137, isolated from a Saharan soil, has been described as a potential biocontrol agent against Botrytis cinerea and other phytopathogens. However,...

Protein Epistasis and the Biophysical Constraints on Catalytic Promiscuity

31/12/2013 00:00

C Crenshaw, J Aljadeff, I Fernandez, C Laurendon, M Defernez, HJ Koo, PE O'Maille, T Sharpee, JP Noel Résumé: The limits of protein evolution are ultimately defined by biophysical constraints. Specifically, the maintenance of protein folding and stability is essential for the emergence novel...
