چکیده
Boris Ephrussi studied fruit flies, yeast, and mouse [3] genetics and development while working in France and the US during the twentieth century. In yeast, Ephrussi studied how mutations in the cytoplasm persisted across generations. In mice he studied the genetics of hybrids and the development of cancer. Working with George Wells Beadle [4] on the causes of different eye colors in fruit flies, Ephrussi's research helped establish the one-gene-one-enzyme hypothesis. Ephrussi helped create new embryological techniques and contributed the theories of genetics and development.

Beadle and Ephrussi's Transplantation Technique for Drosophila
Boris Ephrussi and George Wells Beadle [5] developed a transplantation technique on flies, Drosophila melanogaster [6], which they described in their 1936 article "A Technique of Transplantation for Drosophila [4]." The technique of injecting a tissue from one fly larva into another fly larva, using a micropipette, to grow that tissue in the second larvae, was a means for investigating developm...
متن کاملChromosome Transplantation
T WO papers published in GENETICS in November, 1966 represent a key step in a decade of research in the laboratories of BORIS EPHRUSSI (19011979), research that helped transform mammalian genetics, especially human genetics. These papers, coauthored with MARY WEISS, then a graduate student in EPHRUSSI’S laboratory at Western Reserve University in Cleveland (WEISS and EPHRUSSI 1966a,b), provided...
متن کاملSpecific Reactions of the Ovary to Interspecific Transplantation among Members of the Melanogaster Group of Drosophila.
HE transplantation of ovaries in Drosophila was realized for the first T time by EPHRUSSI and BEADLE (1935b), using the technique which they had devised and applied with such success to the transplantation of the eye discs and other anlagen. Their results showed that the ovaries of D. melamguster can be successfully implanted into male and female larvae of the same species, can become attached ...
متن کاملJames F . Crow and William F . Dove A Reconsideration of the Mechanism of Position Effect Steven Henikoff
T HE title of this article was chosen for two reasons. First, it is the title of a remarkable article published 50 years ago by BORIS EPHRUSSI and EILEEN SUTTON aimed at explaining a widely studied but enigmatic phenomenon (EPHRUSSI and SUTTON 1944). But in addition, by highlighting ideas presented in that article, I will be reconsidering the mechanism of position effect in light of recent work...
متن کاملA brief history of the publication of Biomedical Journals in Iran between 1901 and 1979.
The history of the publication of biomedical journals parallels the development of modern medicine in Iran. Modern medicine was introduced to Iran in the mid-nineteenth century, particularly after the establishment of the Dar al-Fonun School in 1851. The foundation of this collage of higher education was instrumental in further advancement of modern medicine together with the publication of med...
