Evidence is presented to suggest that several early events of zoospore germination in the water mold, Blastocladiella emersonii, are not dependent upon concomitant protein synthesis. The events involve abrupt, dramatic changes in cell architecture. On account of this evidence, as well as evidence available from other sources, we question whether differential protein synthesis provides an exclusive and sufficient mechanism for phenotypic change (i.e., cell differentiation). Rather, we argue that mechanisms for bringing about structural alterations in the preformed machinery of the cell should also be given attention.
有证据表明，水霉艾美球囊霉游动孢子萌发的几个早期事件并不依赖于同时进行的蛋白质合成。这些事件涉及细胞结构的突然、显著变化。基于这一证据以及其他来源的证据，我们质疑差异蛋白质合成是否为表型变化（即细胞分化）提供了唯一且充分的机制。相反，我们认为，导致细胞预先形成的机制发生结构改变的机制也应受到关注。
