As free-living organisms, bacteria are subject to continuous, numerous and occasionally drastic environmental changes to which they respond with various mechanisms which enable them to adapt to the new conditions so as to survive. Here we describe three situations in which the ribosome and its functions represent the sensor or the target of the stress and play a key role in the subsequent cellular response. The three stress conditions which are described are those ensuing upon: a) zinc starvation; b) nutritional deprivation, and c) temperature downshift.
作为自由生活的生物体，细菌不断受到众多且偶尔剧烈的环境变化影响，它们通过各种机制做出反应，从而能够适应新环境以生存下来。在此，我们描述三种情况，其中核糖体及其功能充当应激的传感器或靶点，并在随后的细胞反应中发挥关键作用。所描述的三种应激条件分别是：a）锌饥饿；b）营养剥夺；c）温度下降。
