Abstract
Net rotation and net elongation of a stage IVb Phycomyces growing zone were simultaneously measured minute by minute with a photographic apparatus coupled with a rotating stage. A direct correlation between a growth response and a twist response after either a light stimulus or a house stimulus was found. There were significant irregularities in growth rate in both the elongation and rotation that were not a result of measurement error; these irregularities were poorly, if at all, correlated. We believe that these fluctuations reflect the underlying molecular mechanism of cell wall synthesis.
摘要
使用与旋转台相连的摄影设备，每分钟同时测量处于IVb期的毛霉生长区的净旋转和净伸长。发现光刺激或室内刺激后，生长反应和扭曲反应之间存在直接相关性。伸长和旋转的生长速率均存在显著的不规则性，这并非测量误差所致；这些不规则性之间的相关性很差，甚至几乎没有相关性。我们认为这些波动反映了细胞壁合成的潜在分子机制。
