Light-stimulated incorporation of L-leucine into the gibberellin of Gibberella fujikuroi
Laboratory of Growth and Development, University of Missouri Columbia, Missouri 65201, U. S. A.
Cultures of Gibberella fujikuroi grown under continuous illumination of 1800 lux incorporated over 60% more leucine into the gibberellins than dark controls. In the dark at a C/N ratio of 37.6 Ca++ increased the incorporations of leucine into A3 to essentially the same level as the light-stimulated incorporation. The failure of Ca++ to increase gibberellin synthesis in the dark at a C/N ratio of 9.4 suggested that light and Ca++ were exerting their regulatory roles at different sites.
