Über den Einfluß von Radiumbestrahlung auf Antirrhinum

Die auf der Versammlung der deutschen Gesellschaft ftir Vererbungswissenschaft demonstrierten Antirrhinum sind der Anlafl zu einigen vorl~ufigen Worten tiber die mit Radium angestellten Versuche.Dieselben nahmen ihren Ausgang yon V e g e t a t i o n s p u n k t s -

A short history of Arabidopsis thaliana (L.) Heynh. Columbia-0

“…In 1957 Rédei used his Landsberg seeds in a mutagenesis experiment, where he irradiated the seeds with X-rays and then screened for mutants with interesting phenotypes (meanwhile, in Australia, John Langridge was doing the same for Estland seeds he had received from Laibach) 9, [11][12][13] . Gene mutagenesis by X-ray irradiation had been described in the 1920s for Antirrhinum and Drosophila, and one of Laibach's students, Erna Reinholz, went on to establish this technique for Arabidopsis seeds 4, [14][15][16] . One of the first mutants Rédei recovered was the erecta mutant, which, with its stunted growth, appeared to be quite sturdy, and he thought it might come in handy for further experimentation 9,17 .…”

The Production of Mutations by X-Rays

“…The writer wishes to thank Professor J. T. Patterson for invaluable aid in this experiment, rendered during the writer's absence on the trip. 6 E. Stein (1922Stein ( , 1926 had previously reported numerous phenotypic abnormalities of Antirrhinum, produced by radiation, which were inherited through vegetative reproduction. She also noted abnormalities of chromosome distribution occurring at the reduction division, long after treatment.…”
