library_construction_protocol: Three milliliters of cells from mid-log phase culture were mixed with 6 ml RNAprotect Bacteria Reagent (Qiagen), mixed immediately by vortexing for 5 seconds, incubated for 5 minutes at room temperature, and then centrifuged at 5000g for 10 minutes. The supernatant was decanted and any residual supernatant was removed, then samples were frozen at -80℃. Next, RNA was harvested using RNeasy Plus Mini kit (Qiagen) in accordance with the manufacturer's instruction. Illumina Ribo-Zero rRNA removal kit (bacteria) (MRZMB126) was used with 1 ug of total RNA for the removal of rRNA procedure. Then KAPA RNA HyperPrep kits(Cat.No.08098107702) was used with rRNA-depleted RNA samples for the construction of sequencing libraries. RNA libraries were prepared for sequencing using standard Illumina protocols
