Small non-coding RNA (sRNA) is a type of RNA molecule that is transcribed but not translated into protein in the genome and controls gene expression at the post-transcriptional level.Unlike protein-mediated regulation system,sRNA-mediated regulation can respond to environmental changes quickly when bacteria confront adverse growth environment.RyhB-1 and RyhB-2 are two highly homologous sRNAs in Salmonella,which regulate target genes expression singly or together with the help of regulating factors by base pairing.RyhB-1 and RyhB-2 are major components of Salmonellairon homeostasis regulation at post-transcriptional level by increasing the iron uptake,limiting non-essential iron-utilizing proteins synthesis and accelerating the storage of iron-sulfur protein when iron is scarce.In addition,when Salmonellaencounters various environmental stresses such as oxidative stress,hypoxia or acidic environment,RyhB can also control the production of reactive oxygen species,balance the stability of inorganic substances such as nitrate,and regulate bacterial motility and Salmonellavirulence to cope with environmen-tal changes.This paper is concerned with the physiological characteristics,regulatory mechanisms and functions of Salmonella RyhB to provide guidance for the subsequent study of RyhB.
