Abstract

pH is one of the most fundamental properties of the environments in which microorganisms live. It is, therefore, not surprising that bacteria have evolved mechanisms to sense and respond to pH. One aspect of this response for motile bacteria is to migrate to areas of optimal pH. The paper by P. Tohidifar, M. J. Plutz, G. W. Ordal, and C. V. Rao (J Bacteriol 202:e00491-19, 2020, https://doi.org/10.1128/JB.00491-19) describes how uses bidirectional chemotaxis mediated by four closely related dCACHE_1 chemoreceptors to migrate to regions of neutral pH.

摘要

pH 值是微生物生存环境中最基本的特性之一。因此，细菌进化出了感知和响应 pH 值的机制也就不足为奇了。对于运动细菌来说，这种反应的一个方面是迁移到最佳 pH 值区域。P. Tohidifar、M. J. Plutz、G. W. Ordal 和 C. V. Rao 的论文（J Bacteriol 202:e00491-19, 2020, https://doi.org/10.1128/JB.00491-19）描述了如何利用四个密切相关的 dCACHE_1 化学感受器的双向趋化作用迁移到中性 pH 值区域。
