They are defined epigenetically by the presence of the centromere-specific histone H3 variant\, CENP-A\, yet they are typically embedded in repeat-rich regions of the genome\, making the role of underlying DNA sequences in centromere function and specification unclear. In Drosophila melanogaster\, centromeres correspond to islands of retroelements flanked by tandem satellite repeats\, but their evolutionary stability remains uncertain. We investigate centromere evolution and variation both within D. melanogaster and across its close relatives in the simulans clade (D. simulans\, D. sechellia\, and D. mauritiana). Using a combination of long- and short-read genomic sequencing\, CUT&Tag mapping of CENP-A\, and cytological validation with Fluorescence In Situ Hybridization (FISH)\, we characterize centromere organization\, composition\, and turnover. Within D. melanogaster\, we find that centromere islands are polymorphic across strains from diverse geographic origins\, with reference centromere islands absent in some genomes. We discover structural DNA variation that is associated with a shift in centromeric chromatin\, suggesting that the organization of the reference centromere islands is not essential for centromere function. However\, centromeres may still have conserved features even when their organization is variable\, as we find that CENP-A enriched sequences are similar across strains\, including those with polymorphic centromeres. Across species\, we uncover dramatic centromere reorganization\, including recurrent shifts between retroelements and satellite DNAs over short evolutionary timescales (<240 Kya). None of the D. melanogaster centromere islands are conserved in the simulans clade; instead\, centromeres are largely composed of two clade-specific complex satellites (500 bp and 365 bp). Furthermore\, in D. sechellia\, the dot and X chromosome centromeres have relocated onto telomere-specific retroelements\, creating true telocentric chromosomes. Interestingly\, the G2/Jockey-3 retroelement\, common to all D. melanogaster centromeres\, shows variable enrichment across simulans clade species. Altogether\, our findings demonstrate that centromeric DNA sequences are highly dynamic both within and between species\, with recurrent turnover and structural polymorphisms shaping their evolution. These results highlight the plasticity of centromeric DNA and its role in chromosome function\, consistent with ongoing genetic conflict driving rapid centromere evolution.

How the nucleus reacts to these mechanical cues\, ensuring a tight balance between mechano-protection and mechanotransduction\, is a key yet unresolved question. Here we dissect the spatio-temporal control of nuclear mechanostransduction during EMT\, using Drosophila mesoderm invagination as a model. We found that two conserved pro-EMT genes respond differently to compressive forces: while snail transcription remains unaffected\, compression is sufficient to activate twist transcription within seconds. We further revealed a spatially patterned genome-wide transcriptional response to EMT forces\, with an apical mechanoprotection contrasting with a permissive basal nuclear environment. The direct recording of nascent transcription in response to a controlled nuclear micromanipulation provides compelling evidence of nuclear heterogeneity in the transcriptional response to forces. Overall\, these results reveal that EMT nuclei respond directly and rapidly to mechanical forces\, in a spatially defined pattern. \nSuzanne earned her PhD in 1999 from the University of Toulouse\, followed by a postdoctoral fellowship at the CBM in Madrid\, Spain. In 2005\, she obtained a CNRS research position and worked at the IBV in Nice\, France. From 2008 to 2010\, she was a visiting scientist at Rockefeller University in New York\, USA. She leads a team at the Centre de Biologie Intégrative de Toulouse. She was awarded an ERC Consolidator Grant in 2015\, was appointed CNRS Research Director (DR) the same year\, became an EMBO member in 2022\, and received the Louise Basset Prize from the French Academy of Sciences in 2023. Her team has uncovered how cell death shapes tissues by combining cell biology\, biophysics\, and modeling approaches. Currently\, her research focuses on understanding how the integrity of epithelial tissues—critical for protecting and covering our organs—is maintained.

These predictions critically depend on the evolutionary information available in the sequences of homologous proteins. Beyond modeling individual proteins\, there is now a fundamental challenge to establish the most comprehensive mapping possible of macromolecular assemblies\, which are central to cellular function. This goal faces several constraints\, such as the combinatorial complexity of the interaction space and the type of evolutionary information needed to identify coevolution signals\, which are much weaker at complex interfaces\, especially in disordered regions of proteins. To achieve this goal\, we are setting up computational pipelines [2\, 3] with the aim of targeting the difficult task of predicting interactions mediated by disordered regions and pushing further the current boundaries to predict the structure of assemblies at large scale\, addressing issues of conformational changes [4] and interaction specificities.
