We have demonstrated two interesting facts about the transition from the migration stage to the final fruiting stage of Dictyostelium discoideum. One is that fruiting is favoured on acid substrata, and secondly, migrating slugs tend to migrate towards the acid side of a pH gradient. The suggestion is offered that these results can be interpreted in terms of the effects of NH3. It appears to be an additional mechanism (besides phototaxis and thermotaxis) to assure that the final fruiting takes place in a favourable environment.
我们已经证明了关于盘基网柄菌从迁移阶段到最终结实阶段转变的两个有趣事实。其一，在酸性基质上有利于形成子实体；其二，正在迁移的蛞蝓倾向于朝着pH梯度的酸性一侧迁移。有人提出，这些结果可以用NH₃的作用来解释。这似乎是一种额外的机制（除趋光性和趋温性之外），以确保最终的结实过程在有利的环境中发生。
