Tensile tests were conducted on the photoresponsive stage IVb sporangiophore of the fungus Phycomyces before and after a saturating light stimulus. The results demonstrate that an increase in the mechanical extensibility of the cell wall occurs after the light stimulus. This increase in mechanical extensibility occurs in the growing zone of the sporangiophore. The majority of this increase occurs in the region about 300 umeters beneath the sporangium.
对光照刺激前后的真菌水玉霉 IVb 期游动孢子梗进行了拉伸测试。结果表明,光照刺激后细胞壁的机械拉伸性增加。这种机械拉伸性的增加发生在游动孢子梗的生长区。大部分增加发生在距孢子囊约 300 微米的区域。
