Forum 2023: LabEx TULIP / FR AIB

The FR AIB and LabEx TULIP jointly organise their annual forum on October 12 and 13 in the brand-new Agrobiosciences building. The first half-day will focus on the FRAIB environment, with an overview of the technological facilities, followed by Young Scientists talks, granted in 2022. During the following afternoon and Friday, TULIP LabEx will present a program combining presentations by its members and international guests.

An integrated analysis of plant and bacterial gene expression in symbiotic root nodules using laser-capture microdissection coupled to RNA sequencing

Rhizobium-induced root nodules are specialized organs for symbiotic nitrogen fixation. Indeterminate-type nodules are formed from an apical meristem and exhibit a spatial zonation which corresponds to successive developmental stages. To get a dynamic and integrated view of plant and bacterial gene expression associated with nodule development, we used a sensitive and comprehensive approach based upon oriented high-depth RNA sequencing coupled to laser microdissection of nodule regions.

Genome of model legume Medicago truncatula sequenced

Dans le cadre d'un consortium international, des chercheurs du LIPM (INRA-CNRS), en collaboration avec le Génoscope (CEA- Institut de Génomique) sont parvenus à séquencer le génome d’une légumineuse modèle proche du pois ou de la luzerne cultivée : Medicago truncatula. Le séquençage de son génome donne accès aux gènes d'intérêt potentiellement utilisables pour d'autres cultures. Cette légumineuse a en effet une capacité intéressante, elle fixe, grâce à une symbiose avec des bactéries, l’azote présent dans l’atmosphère. Elle ne requiert donc pas, contrairement à beaucoup de ses semblables, d’intrants... Une recherche qui, transférée à d’autres espèces, ouvre la voie à une agriculture plus respectueuse de l’environnement.

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.

Do stream fish track climate change ? Assessing distribution shifts in recent decades

Understanding the ability of species to shift their distribution ranges in response to climate change is crucial for conservation biologists and resources managers. Although freshwater ecosystems include some of the most imperilled fauna worldwide, such range shifts have been poorly documented in streams and rivers and have never been compared to the current velocity of climate change. Based on national monitoring data, we examined the distributional changes of 32 stream species in France and quantified potential time lags in species responses, providing a unique opportunity to analyse range shifts over recent decades of warming in freshwater environments.

Tournesol : un nouvel outil pour mesurer le manque d’eau

Plant or soil water status is required in many scientic elds to understand plant responses to drought. Because the transcriptomic response to abiotic conditions, such as water decit, reects plant water status, genomic tools could be used to develop a new type of molecular biomarker.

Transient Hypermutagenesis Accelerates the Evolution of Legume Endosymbionts following Horizontal Gene Transfer

Horizontal gene transfer has an extraordinary impact on microbe evolution and diversification, by allowing exploration of new niches such as higher organisms. This is the case for rhizobia, a group of phylogenetically diverse bacteria that form a nitrogen-fixing symbiotic relationship with most leguminous plants. While these arose through horizontal transfer of symbiotic plasmids, this in itself is usually unproductive, and full expression of the acquired traits needs subsequent remodeling of the genome to ensure the ecological success of the transfer. Here we uncover a mechanism that accelerates the evolution of a soil bacterium into a legume symbiont.

Structural and functional partitioning of bread wheat chromosome 3B

Publication of the first reference sequence of the biggest bread wheat chromosome. Thanks to an international collaboration, coordinated by INRA jointly with CEA (Genoscope), CNRS and Université d’Evry in France, this major achievement will allow the identification of numerous genes of agronomic interest, and accelerate wheat improvement. Results are published in Science on July 18th, 2014.

Species traits and phylogenetic conservatism of climate-induced range shifts in stream fishes

Understanding climate-induced range shifts is crucial for biodiversity conservation. However, no general consensus has so far emerged about the mechanisms involved and the role of phylogeny in shaping species responses has been poorly explored. Here, we investigate whether species traits and their underlying phylogenetic constraints explain altitudinal shifts at the trailing and leading edges of stream fish species ranges. We demonstrate that these shifts are related to dissimilar mechanisms: whereas range retractions show some support for phylogenetic clustering due to a high level of conservatism in thermal safety margins, range expansions are underpinned by both evolutionarily conserved and labile traits, notably trophic position and life-history strategy, hence decreasing the strength of phylogenetic signal. Therefore, while climate change brings many difficulties in establishing a general understanding of species vulnerability, these findings emphasize how combining trait-based approaches in light of the species evolutionary history may offer new opportunities in facing conservation challenges.

From museums to genomics: old herbarium specimens shed light on a C3 to C4 transition

Collections of specimens held by natural history museums are invaluable material for biodiversity inventory and evolutionary studies, with specimens accumulated over 300 years readily available for sampling. Unfortunately, most museum specimens yield low-quality DNA. Recent advances in sequencing technologies, so called next-generation sequencing, are revolutionizing phylogenetic investigations at a deep level.

Multihost Experimental Evolution of the Pathogen Ralstonia solanacearum Unveils Genes Involved in Adaptation to Plants

Ralstonia solanacearum, the causal agent of a lethal bacterial wilt plant disease, infects an unusually wide range of hosts. These hosts can further be split into plants where R. solanacearum is known to cause disease (original hosts) and those where this bacterium can grow asymptomatically (distant hosts). Moreover, this pathogen is able to adapt to many plants as supported by field observations reporting emergence of strains with enlarged pathogenic properties. To investigate the genetic bases of host adaptation, we conducted evolution experiments by serial passages of a single clone of the pathogen on three original and two distant hosts over 300 bacterial generations and then analyzed the whole-genome of nine evolved clones.
