Constructed strains using the Hfq-MicC tool. PpsbA2 M promoter was used for expressing all sRNAs, while Pcpc560 was utilized to express the chaperone hfq except WT-HMMA1(the*). TrbcL was used as the terminators. a Schematic of the WT-HMFA strain, in which slr1511, slr1322, and sll1069 were downregulated. b Schematic of the WT-HMMA1 strain, in which slr2023 and slr1511 were downregulated. c Schematic of the WT-HMMA2 strain, in which slr2023, slr1511, slr1322, and sll1069 were downregulated. d Schematic of the WT-HMMA1(the*) strain, in which slr2023 and slr1511 were downregulated. A modified promoter Ptrc contained a theophylline-responsive riboswitch was used to control the expression of hfq
