Publicity about Antibiotic Research

Framed photograph of David Hopwood showing Hopwood above various coloured Petrie dishes, colour print, London Picture Service (4/1402/01/12/C) with typed page glued to back describing the background to the photograph entitled 'Breakthrough in Antibiotic Research'. Used for publicity about the first hybrid antibiotic using genetic engineering called meder-rhodin, produced at John Innes by a team led by Hopwood. Meder-rhodin was made by transferring genes from one strain of streptomycetes into another.

Fruit trees in pots showing results of cross and self-pollination (apple, cherry, pear, plum); fruit sports and chimeras; blackberry 'Merton Thornless'; rogue tomato; radishes (1), loganberry (1). Also four copies of picture from Pomona Herefordiensis (1811).
