Phototropism in Phycomyces as investigated by focused laser radiation
Science (New York, N.Y.)
|July 24, 1970
Abstract:
The phototropic response and distribution of photopigment in the sporangiophore of Phycomyces was investigated with a microillumination pattern. The data support the hypothesis that phototropism results from greater stimulation of growth in regions of more intense illumination and indicate that the photoreceptor extends to the outer wall of the sporangiophore.
