Transcriptome analysis of the response of Lactiplantibacillus plantarum IMAU10120 to infection by phage P2

Abstract

Bacteriophage infection of lactic acid bacteria remains a significant problem in the food fermentation industry. To improve understanding about the underlying mechanism of phage–host infection, we used RNA sequencing technology to investigate the effect of phage infection on the expression of host genes based on the one-step growth curve. Results identified a total of 3207 genes, of which 178 showed a significant differential expression in phage-infected host. Moreover, bioinformatic analyses unravelled that these genes regulated many processes in host bacteria, including ribosome, RNA polymerase, DNA replication and metabolic pathways. This study further elucidates the response of host bacteria to phage infection. These results provide valuable data for developing effective phage control measures and improving the success rate of fermentation in the dairy industry.
