Catarina Satie Takahashi, Brazilian geneticist (Bauru, São Paulo State 20 April 1942 –

From Japanese ancestry

Showed that low doses of radiation are able to induce chromosome breaks enhancing the rate of chromosomal translocations

Cytogenetical studies of the effects of high natural levels in Tityus bahiensis (Scorpiones, Butidae) from Morro do Ferro, Brazil. Radiation Research 67:371-81, 1976

Observed that scattering radiations display mutagenic action more efficient than direct radiations (1977)

With S. Ichikawa. Somatic mutation frequencies in the stamen hairs of stable and mutable clones of Tradescantia after acute gamma-ray treatments with small doses. Mutation Research 45(4):195-204, 1977

Developed methodology for obtaining mitotic chromosomes of fishes

With L.A. Bertollo & O. Moreira Filho. Cytotaxonomic considerations of Hoplias lacerdae (Pisces), Erythrinidae). Braz.J. Genet. 1:103-20, 1978

With Cristiano Profeta patented an electric trough for electrophoresis in slides (2013)
