To investigate the change in transcriptional profiles of 336gr-1 derivatives (especially, LSUPB145) between solid and liquid cultures, RNA-seq was again performed. The transcriptomes of bacterial cultures of LSUPB145 grown on solid and in liquid media were compared. The differentially expressed genes were selected. Strikingly, many genes from this selection were also previously identified as potential QS-dependent genes. These genes encode proteins including ferredoxin, ABC transporter component, UspA domain containing protein, FAD/FMN-binding oxidoreductase, AraC regulator, RebAB proteins, thioesterase super family protein, (3R)-hydroxymyristoyl-ACP dehydratase and LuxR type autoinducer-binding regulator. Therefore, it is possible that some other alternative regulator can perform similar global regulatory functions as AHL QS in B. glumae.
