L'ancienne équipe Camadro a contribué à la publication d'un nouvel article dans The ISME Journal : Iron limitation promotes metabolic cross-feeding between cheese ripening bacteria Résumé : Iron is a limiting micronutrient in various environments, and its scarcity orchestrates microbial interactions across diverse ecosystems. The cheese surface, which is oxic, iron-limited, and a host of moderately complex…

L'équipe Guichet a contribué à la publication d'un chapitre de livre: Sexual Development in Fungi Résumé : This chapter explores the genetic and cellular mechanisms governing sexual reproduction in fungi, with a focus on Ascomycota and Basidiomycota. Sexual reproduction is orchestrated by the genetic regulation of mating identity, which ensures the recognition and differentiation of compatible partners.…

L'équipe Dumont a publié un nouvel article dans médecine / science : The interkinetic envelope: a discovery that challenges our knowledge of oocyte meiosis   El Mossadeq L, Dumont J. L’enveloppe d’intercinèse - Une découverte qui bouscule notre connaissance de la méiose ovocytaire [The interkinetic envelope: a discovery that challenges our knowledge of oocyte meiosis]. Med Sci…

L'équipe Duharcourt a publié un nouvel article dans BMC Biology : The tiny germline chromosomes of Paramecium aurelia have an exceptionally high recombination rate and are capped by a new class of Helitrons Background Paramecia belong to the ciliate phylum of unicellular eukaryotes characterized by nuclear dimorphism. A diploid germline micronucleus (MIC) transmits genetic information across sexual generations.…

L'équipe Konstantinides a publié un nouvel article dans Nature neuroscience : Spatial, temporal and Notch determination of terminal selector expression controls neuronal cell fate in the Drosophila optic lobe Résumé : In the medulla of the Drosophila optic lobe, the identity of each neuronal type is specified in progenitors and newborn neurons via the integration of temporal, spatial and…

L'équipe Prioleau a publié un nouvel article dans Nucleic Acid Research : Transcription at an inducible common fragile site reveals replication origin strength hierarchy Résumé : While genome-wide analyses in vertebrates suggest that transcription negatively regulates replication origin activation, thereby shaping the landscape of replication initiation, it remains unknown whether efficient replication origins can overcome this suppression…
