Abstract
Aphidicolin inhibits DNA synthesis and nuclear division in spores of Anemia phyllitidis. In spite of blocked DNA replication, spores germinate under continuous dark conditions, if induced by addition of 5 x 10(-5) grams per milliliter gibberellic acid. Differentiation of aphidicolin-treated prothallia indicate the existence of a prepattern in the dry spore which is realized independent of cell division during early events of spore germination.
摘要
阿非迪可林抑制凤尾蕨孢子的 DNA 合成和核分裂。尽管 DNA 复制被阻断，如果在持续黑暗条件下加入 5×10（-5）克/毫升赤霉素诱导，孢子仍会发芽。阿非迪可林处理的原叶体分化表明，在孢子的干燥状态下存在一个预图案，该预图案在孢子发芽的早期事件中独立于细胞分裂而实现。
