Summer School must go on...

If the main goal of the TULIP Summer School was to train students in Integrative Ecology and Biology during an intensive and immersive week in the Pyrénées, it is now of interest to extend the interactions initiated at this occasion between teachers and students beyond this week.

Michel Loreau - senior chair 2012

Before landing in Ariège, Michel Loreau, a great name of ecology dragged up in many corners of the world, relentlessly inventorying species or trying to understand ecosystem functioning while remaining an activist for biodiversity. His research focuses more specifically on gathering disjoint fields: ecosystems functioning, community organization and evolution of species. After his thesis in Brussels and a position at the Pierre et Marie Curie University then at the McGill one, he will now keep on working in Moulis, on behalf of the Experimental Station of Ecology (SEEM). He came here with his team thanks to the Midi-Pyrenees Regional Council, CNRS and TULIP LabEx.

Nucleo-cytoplasmic basal resistance regulator EDS1 connects pathogen effector recognition to cell compartment-specific immune responses

Bacterial typeIII effectors are recognized by plant intracellular nucleotide binding–leucine-rich repeat (NB-LRR) receptors. So far, processes linking activation of these receptors to downstream defense responses remain elusive.

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

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 different Ca2+ sensors and calmodulin (CaM) is one of the best characterized in eukaryotes. Calmodulin-like (CML) proteins extend the Ca2+-toolkit in plants; they share sequence similarity with the ubiquitous and highly conserved CaM but their roles at physiological and molecular levels are largely unknown.

Plant-activated Bacterial Receptor Adenylate Cyclases Modulate Epidermal Infection in the Sinorhizobium meliloti-Medicago Symbiosis

Legumes and soil bacteria called rhizobia have co-evolved a facultative nitrogen-fixing symbiosis. Establishment of the symbiosis requires bacterial entry via root hair infection threads (ITs) and, in parallel, organogenesis of nodules that are subsequently invaded by bacteria. Tight control of nodulation and infection is required to maintain the mutualistic character of the interaction. Available evidence supports a passive bacterial role in nodulation and infection, after the microsymbiont has triggered the symbiotic plant developmental program.

Hybridization and barriers to gene flow in an island bird radiation

While reinforcement may play a role in all major modes of speciation, relatively little is known about the timescale over which species hybridize without evolving complete reproductive isolation. Birds have high potential for hybridization, and islands provide simple settings for uncovering speciation and hybridization patterns. Here we develop a phylogenetic hypothesis for a phenotypically diverse radiation of finch-like weaver-birds (Foudia) endemic to the western Indian Ocean islands.

Structure - function analysis of the extracellular domain of NFP, a putative Nod factor receptor

Legume plants are able to form a root endosymbiosis with some soil bacteria collectively called rhizobia. This interaction between legumes and rhizobia is highly specific and depends on the recognition by the plant of molecules produced by the rhizobia, called Nod Factors (NF). Hence, precise NF structures are required depending on the host plant. These data provide new information about NFP structure and on the mechanisms of NF recognition in the different steps of symbiosis in M. truncatula.

Beyond DNA: integrating inclusive inheritance into an extended theory of evolution

Current evolutionary approaches reduce heredity to the sole genes. However, evidence is accruing that various forms of non-genetic information are transmitted across generations and thus participate to evolution. In a paper published in Nature Reviews Genetics, an international team encompassing three members of the federation de Recherche 3450 (EDB, UMR 5174 CNRS-Université Paul Sabatier-ENFA and “SEEM, USR 2936 CNRS) call for a more inclusive paradigm integrating all forms of non-genetic heredity into a single theory of evolution. It is the party taken by the TULIP Labex project to which three of the authors take part.

Homogenization patterns of the world’s freshwater fish faunas

The world is currently undergoing an unprecedented decline in biodiversity, which is mainly attributable to human activities. For instance, nonnative species introduction, combined with the extirpation of native species, affects biodiversity patterns, notably by increasing the similarity among species assemblages. This biodiversity change, called taxonomic homogenization, has rarely been assessed at the world scale.

Genome of model legume Medicago truncatula sequenced

Scientists from LIPM (INRA-CNRS) in collaboration with Génoscope (CEA-Institut de Génomique), as part of an international consortium *, have reported the genome sequence of a legume, Medicago truncatula (Mt) also known as Barrel Medic. This sequence provides easy access to the location of genes of interest in crop legumes (pea, field bean, lentil, alfalfa, clover) which will greatly facilitate breeding. Legumes have the capacity to fix atmospheric nitrogen; as a result legume crops do not require nitrogen fertilizers, which represents a real asset for a sustainable and more environmentally friendly agriculture. Results are published in Nature on November 17th 2011.

How is dispersal integrated in life histories: a quantitative analysis using butterflies

As dispersal plays a key role in gene flow among populations, its evolutionary dynamics under environmental changes is particularly important. The inter-dependency of dispersal with other life history traits may constrain dispersal evolution, and lead to the indirect selection of other traits as a by-product of this inter-dependency.
