【 摘 要 】

The effects of the benzene compounds from plants, respectively cinnamic acid, coumaric acid, ferulic acid, caffeic acid, and cinnamic aldehyde on growth and hyphal morphology of Neurospora crassa, were investigated. Cinnamic acid, ferulic acid and cinnamic aldehyde inhibited colony growth, but produced no visible alterations on hyphae. Caffeic acid and coumaric acid did not inhibit growth, but changed hyphal morphology. The results suggest that caffeic and coumaric acids probably affect polarity maintenance (the continued deposition of wall material at the extending tip), while cinnamic aldehyde, ferulic and cinnamic acids decrease growth rate, but did not change hyphal polarity. The actin cytoskeleton and the Spitzenkörper appeared diffuse and not clearly visible when one of the benzene compounds was present in the culture.
