1955: Kinetin Arrives. The 50th Anniversary of a New
Plant Hormone
Richard Amasino*

Fifty years ago, scientists from the Botany and Bio-
chemistry departments at the University of Wisconsin
announced the isolation, crystallization, characteriza-
tion, and synthesis of 6-furfurylaminopurine (Miller
et al., 1955a, 1955b, 1956), a plant hormone in a class
now referred to as cytokinins (Skoog et al., 1965). They
proposed the trivial name kinetin for this substance,
and described its ability to promote cell division in test
tissues from tobacco (Nicotiana tabacum). The discovery
of kinetin marked the culmination of several years of
research on a variety of projects conducted by many
people in the two departments.
A description of the little victories, the interesting
twists, and the roles of persistence, patience, and good
luck in this discovery has never been presented in
