Daphne J. Osborne (7 March 1930[1][2] – 16 June 2006) was a British botanist. Her research in the field of plant physiology spanned five decades and resulted in over two hundred papers, twenty of which were published in Nature.[3][4] Her obituary in The Times described her scientific achievements as "legendary";[1] that from the Botanical Society of America attributed her success to "her wonderful intellectual style, combined with her proclivity for remarkable and perceptive experimental findings".[5]
Her research focused on plant hormones, seed biology and plant DNA repair. She is best known for her work on the gas ethylene, in particular for demonstrating that ethylene is a natural plant hormone, and that it is the major regulator of ageing and the shedding of leaves and fruits. She also originated the concept of the target cell as a model for understanding plant hormone action.
