Boris Ephrussi

from Wikipedia, the free encyclopedia

Boris Ephrussi ( Russian Борис Самойлович Эфрусси ; born May 9, 1901 in Moscow , † May 2, 1979 in Paris ) was a French geneticist of Russian descent .

life and work

Ephrussi emigrated from Russia to France after the October Revolution . He graduated from the Sorbonne in 1922 in zoology and received his doctorate in experimental embryology in 1932. At that time he was concerned with the influence of external stimuli on the development of fertilized sea urchin eggs and with cell cultures. In 1934 he went to Caltech with Thomas Hunt Morgan on a Rockefeller Fellowship . There they collaborated with George Beadle on the genetic control of eye coloring in Drosophila, using micropipettes and micromanipulators to transplant parts of organs and tissues from Drosophila larvae. The collaboration was continued when Beadle stayed in Paris in 1935 and Ephrussi at Caltech in 1936 and was the beginning of the one-gene-one-enzyme thesis for which Beadle and Tatum received the Nobel Prize.

During World War II, Ephrussi (who was Jewish) was a refugee at Johns Hopkins University . He then returned to France, where he did research at the "Institut de Biologie Physicochimique" (IBPC, Rothschild Institute) in Paris and then at the CNRS in Gif-sur-Yvette. He turned in particular to genetic research on wheat cells and genetics outside the cell nucleus (in the mitochondria ), which was continued by his student Piotr Slonimski and his school. In 1966 he and Mary Weiss succeeded in creating hybrids of somatic cells from different species. For Ephrussi, this was just an advancement of techniques used to study the differentiation of cells in embryonic development, but the techniques soon found wide use in mammalian genetics.

Jacques Monod is one of his students .
