#PlantScienceClassics #2: Radiation-induced mutagenesis. 100 years ago, in 1921, Emmy Stein developed radiation-induced #mutagenesis of #Antirrhinum majus plants. But today it seems that her invaluable contribution is being ignored… Read on doi.org/10.1007/BF0195… 
Mutagenesis is now an invaluable tool to understand a gene’s function. In the early 1900s, when the hereditary substance was not even identified yet, it was an even more important tool, which Emmy Stein added to the small toolbox available to biologists at the time.
Stein used gamma rays from radium to irradiate both, adult plants & seeds, & showed the effects of different doses & different lengths, determining the lethal dose, &, importantly, the dose that induced weak mutants, that would still produce seeds to continue experimental work.
