      The AxioZoom (Zeiss) and its ApoTome module are installed !!!
      The Zeiss Axio Zoom.V16 combines the advantages of standard microscopes and stereomicroscopes.



    • A peculiar methylation pattern for fine tuning of R gene expression

      Genes conferring resistance to diseases in plants, also named R genes, are essential players of sustainable agriculture. NB-LRR (nucleotide biding site – leucine rich repeat) R genes constitute one of the larger and most diversified gene families in plants. Nevertheless, R genes can represent a cost for plants. Their expression has therefore to be finely tuned. Despite their agronomic importance, this question has been poorly addressed.



    • Whole-genome chromatin landscape of symbiotic genes

      Advances in deciphering the functional architecture of eukaryotic genomes have recently been facilitated by technological advances in sequencing techniques, allowing a more appropriate representation not only of coding genes, but also of repeated elements and non-coding RNAs in genomic sequence assemblies.



    • The transcriptional landscape of polyploid wheat

      Wheat is one of the main food sources for the planet. The International Wheat Genome Sequencing Consortium has successfully completed a detailed analysis of the genetic content of subgenomes and the structural organization of all chromosomes. Moussa Benhamed and his team at IPS2 and in collaboration with SPS participated in this important project. These resources are fundamental and will accelerate our understanding of the mechanisms regulating gene expression in this species of great agronomic interest.



    • Mtnoot1, Mtnoot2 and the identity of symbiotic nodules

      Symbiotic interactions between legume plants and rhizobia result in the formation of a specific symbiotic organ called the nodule. In this new work, we report the identification and the characterization of the MtNODULE ROOT2 (MtNOOT2) gene and its role in nodule identity.



    • The roses: The decoded genome

      The rose... an ornamental plant emblematic of the history of humanity.
      Its genome has been successfully decoded by an international consortium involving ENS de Lyon, IPS2, INRA, CEA, CNRS and Université Claude Bernard Lyon 1.
      Two IPS2 teams, the Floral Development and Sex Determinism team (A. Bendahmane) and the Chromatin Cell Cycle and Development team (M. Benhamed) contributed to this work.



    • Un complexe de trois protéines PPR au moins est nécessaire à l’édition de dizaines de sites dans les ARN mitochondriaux et chloroplastiques des végétaux supérieurs

      Dans un article récemment publié dans la revue PNAS, l’équipe de Claire Lurin à IPS2 révèle qu’un complexe de trois protéines PPR au moins est nécessaire à l’édition de dizaines de sites dans les ARN...



    • Splicing regulation by long noncoding RNAs

      In the last years, the advent of novel sequencing techniques allowed the identification of thousands of RNAs that are expressed all along the genome that do not seem to code for proteins as usual mRNAs...



    • La réponse des plantes aux pathogènes implique un remodelage de la chromatine

      Les plantes détectent les attaques pathogènes à travers la perception de signaux appelés PAMPs (Pathogen-Associated Molecular Patterns) qui induisent des cascades de signalisation pour activer des...
