Daisy Roulland-Dussoix (1936 -2014) molecular microbiologist, was one of the discoverers of restriction enzymes during her doctoral studies, for which a Nobel prize was awarded to Werner Arber.

Early Life[edit]

Daisy Roulland-Dussoix was born September 9th, 1936 in Geneva, Switzerland. Daughter of Edmond Louis Dussoix and Elsa Margaetha (Sauerbrey) Dussoix.

Education[edit]

Daisy Roulland-Dussoix (née Daisy Dussoix) gained her first degree in Chemistry and Biology from University of Geneva (1958), followed by her doctorate in Biophysics (1964).

Scientific career[edit]

She worked for her PhD with Werner Arber and Eduard Kellenberger, Swiss microbial geneticists, at the time when the barriers to infection of bacterial cells by virus (bacteriophage) first became apparent, leading to the discovery of restriction and modification enzymes that have subsequently became essential molecular biology tools.[1] These enzymes result in cleavage of DNA by enzymes at sites characterised by specific sequences unless these are protected by prior enzymatic modification to the DNA bases. This system protects bacterial cells from viral infection. The research of Grete Kellenberger-Gujer had already demonstrated that phage DNA could be degraded by host bacterial cells. Daisy Dussoix and Werner Arber showed that this process required enzymes, resulting in two publications that paved the way for discovery and isolation of the restriction and modification enzymes involved.[2][3] [4] They had previously presented these results at the First International Biophysics Congress in Stockholm in 1961.

In 1964 Dussoix moved to Stanford University, USA, funded by a Jane Coffin Childs postdoctoral fellowship to work with Robert Lehman. She subsequently worked as Assistant Professor in Residence in the Department of Microbiology from 1968 at the University of California, San Francisco and continued to study DNA restriction and modification with Herbert W Boyer.[2] She later worked with the research group of Harold E. Varmus on understanding how avian src protoncogenes worked.[5] She subsequently moved to the University of California, Berkeley.

In early 1980 Dussoix-Roulland returned to Europe and worked at the Institut Pasteur in Paris on detection of mycoplasmas using PCR-based molecular methods. She was appointed Group Head of the Mycoplasma Laboratory in 1987 in the Viral Oncology Unit of Luc Montagnier. Her publications from these years focused on mycobacterium and mycoplasmas, specifically genetic and molecular characterization and the development of detection methods.

Contributions, and controversy over recognition of Dussoix's contribution towards Werner Arber Nobel Prize[edit]

Dussoix-Roulland was a member of the research groups of two future Nobel Prizewinners (Werner Arber (for discovery of restriction enzymes), and the group of Harold Varmus and J. Michael Bishop (for the cellular origin of retroviral oncogenes). Her contribution to these discoveries, and whether she should have had greater recognition, has been a topic of controversy.[6] Specifically, the work on host-controlled DNA modification and discovery of restriction endonucleases, which earned Arber the Nobel prize in Physiology or Medicine (along with Hamilton Smith and Daniel Nathans), was described in two 1962 articles where Dussoix and Arber were the sole authors.[7][8] In a letter to her brother and sister-in-law, written in 1978, shortly after the award of the Nobel prize to Arber, Dussoix-Rolland states that "I am very furious, because apparently he has not even mentioned my name, and I have done half of the work for which he received the Nobel Prize" .[9] In Arber's biographical sketch on the Nobel Prize site, it is stated that the findings "that restriction and modification were properties of the bacterial strains and acted not only on infecting bacteriophage DNA, but also on cellular DNA as manifested in conjugation experiments" were reported by himself and Daisy Dussoix for the first time to the scientific community during the First International Biophysics Congress held in Stockholm in the summer of 1961.[10] Yet, Dussoix is not thanked and credited individually as a collaborator directly involved in the work rewarded by the Nobel prize.[10] The text of Arber's Nobel lecture states that together with Grete Kellenberger "Daisy Dussoix, a Ph. D. student, studied the breakdown of DNA from irradiated phage λ upon infection of normal host bacteria" .[11] In a letter to her brother (December 7, 1978), Dussoix states: "I have worked with Werner from 1959 to 1963, at which time they (Edouard) forced me to change my PhD thesis project, reportedly because I could not use work done with Werner, but in reality because Werner, after returning from the USA, in order to be paid decently had to engage himself on research on radiation, for which at the time there was more money. Since Werner was not at all interested in doing the research for which he was paid, somebody had to do it, and that somebody was me, this is why for more than a year before my departure to the USA I was not able to work on restriction, and that should not count for my thesis. In any event, I think that the Nobel Prize was awarded for the two papers published in 62".[12]

Personal life[edit]

In 1964 she married Daniel Roulland, chef at The Star in San Francisco. In 1996 she contracted malaria and as a consequence suffered from long-term neurological problems. Following the death of her husband, she returned to Geneva in 2006, where she died in 2014.
