摘要: 细菌生存的环境复杂多变, 经常处于营养元素过剩或缺乏的状态。因此, 细菌必须及时准确地调节其基因表达以适应不断变化的营养环境, 才能得以生存。小RNA(small RNA, sRNA)是近年来在细菌中发现的一类RNA调控子, 在细菌应对营养应激的基因表达调控中发挥重要作用。就细菌sRNA的特点及其抗营养应激的作用进行综述。

Abstract: The survival environment of bacteria is complex and volatile, and it is usually in a state of over-nutrition or denutrition. Therefore, bacteria only are able to survive by using sophisticated regulation system to timely and accurately adjust its gene expressions to adapt to the changing nutritional environment. Bacterial small RNA(small RNA, sRNA)playing an important role in regulating expression of bacterial gene in response to nutrient stress, is a class of RNA regulators discovered in bacteria in recent years. This article reviews the characters and the functions of bacterial small RNA resistance to nutrient stress.

Key words: bacterial small RNA, regulatory networks, nutrient stress
