Wouldn’t you agree that the walls of Igmors – Bâtiment 400 could tell a thousand stories? It stands here on Rue Gregor Mendel a four-story university building. But its true significance lies in the scientific legacy it holds.
Welcome to Igmors – Bâtiment 400 a cornerstone of scientific research in Paris. Today we will delve into its history. We will uncover the groundbreaking work that shaped modern genetics and microbiology.
Back in 1963 this building now known as Igmors – Bâtiment 400 was just the beginning. It was then called the Groupe des Laboratoires de Biologie Expérimentale. Imagine the atmosphere. Two geneticists P. L’Héritier and G. Rizet alongside phytopathologist J. Chevaugeon fueled its creation.
By 1966 most teams consolidated into Laboratoire Associé au CNRS LA86. This later became Institut de Génétique. G. Rizet took the helm shaping research around three core areas. These were Genetics Cytology and Virology.
One research theme focused on Genetics and Biochemistry of Rhabdovirus. A. Berkaloff G. Brun and P. Vigier successively led this. However this focus shifted in 1983 when A. Flamand became Director of the Laboratoire de Génétique des Virus in Gif.
J. André a pioneer in electron microscopy led Cytology studies. His departure in 1972 didn’t halt progress. J-C. Mounolou continued studying mitochondrial biogenesis. He researched Saccharomyces cerevisiae yeast and Xenopus oogenesis. He also studied the mitochondrial genome of Drosophila and rabbits focusing on Population Genetics and Evolution.
D. Zickler a former student of G. Rizet made a name studying meiosis. She used the filamentous fungus Sordaria macrospora. Her work gained international recognition.
J. Proust and C. Prudhommeau former students of P. L’Héritier continued Drosophila research until 1988. However G. Rizet’s teams primarily conducted genetic research using filamentous fungi to analyze various biological problems.
G. Rizet discovered vegetative incompatibility and senescence in Podospora anserina. These phenomena remain under study even now. M. Picard studied translation fidelity and its impact on fungal physiology and development. J-M. Simonet and D. Zickler characterized mutants of sexual development.
Moreover G. Rizet and J-L. Rossignol chose Ascobolus immersus as a model for meiotic recombination. Later G. Rizet discovered genetic instability due to transposons in filamentous fungi.
J. Beisson a former student introduced Paramecium as a genetic model in France. This system proved useful for studying nucleo-cytoplasmic relations. It was also useful for studying cellular morphogenesis and epigenetic phenomena. However Beisson left LA86 in 1973.
In 1974 P. Vigier became director steering the lab towards Molecular Genetics. Transforming organisms became essential. This was already happening for S. cerevisiae yeast in 1978. Neurospora crassa in 1979 and Aspergillus nidulans in 1983 followed.
Personalities like Michel Guérineau in 1981 and Michel Jacquet in 1984 boosted this shift. M. Jacquet studied the role of cyclic AMP in cell division. M. Guérineau introduced Streptomyces filamentous bacteria. These bacteria showed unique regulation and differentiation phenomena. They also produced many antibiotics.
In 1982 Y. Brygoo joined M. Picard’s team focusing on sexual development in Podospora. By 1986 Godeleine Faugeron brought molecular biology expertise. Analyzing transformation in Ascobolus led to discovering MIP. MIP or Méthylation Induite Pré-méiotiquement is a mechanism. It ensures genome quality control by inactivating over-expressed sequences.
When J. Chevaugeon retired in 1986 Y. Brygoo took charge of the Cryptogamie team. It integrated into LA86. By 1989 five phytopathogenic fungi were effectively transformed. This enabled original research on transposons.
M. Bolotin-Fukuhara’s team developed their work on mitochondrial biogenesis in S. cerevisiae. This involved genetic and molecular approaches. J-C. Mounolou directed the Institut de Génétique from 1986. He drove the creation of the Institut de Génétique et Microbiologie IGM.
Thus Igmors – Bâtiment 400 stands as a testament to decades of scientific exploration. From classical genetics to molecular breakthroughs its walls echo with discovery. Its legacy continues to inspire future generations of scientists.
