Abstract
The effect of artificial gravity on the growth of a microorganism, Dictyostelium discoideum, was studied and the following results were obtained: (a) Germination efficiency increased as gravity increased up to 3 gravities. (b) Cell differentiation was influenced by gravity. Retardation of spore formation or reduction in the spore fraction was observed at hypergravity. (c) Fruiting bodies were taller at hypergravity and smaller at simulated microgravity when compared at 1 gravity. It is suggested that modulation of gravity provides useful information on the mechanisms of life.
摘要
研究了人工重力对微生物盘基网柄菌生长的影响，得到以下结果：（a）随着重力增加到 3 倍，发芽效率增加。（b）重力影响细胞分化。在超重力下观察到孢子形成延迟或孢子分数减少。（c）与 1 倍重力相比，超重力下的子实体更高，模拟微重力下的子实体更小。提示调节重力为生命机制提供了有用的信息。
