Abstract
Wild-type sporangiophores at stage IVb (final developmental stage after sporangium formation) ofPhycomyces show a pronounced positive phototropism to unilateral white light. We found that the maximal bending angle was larger in thin sporangiophores than in thick ones, and larger in the sporangiophores containing a small amount of β-carotene than in those containing a large amount of it. These phenomena probably occur because of the increase in length of intracellular light path or in the intracellular light-attenuation coefficient, as supported theoretically.
