Relative mRNA expression of the a P–H+-ATPase (Mha1) and b aquaporin (ZmPIP1) genes in maize roots treated or untreated with 50 mg C L−1 humic acid (HA), H. seropedicae (Bac) or 50 mg C L−1 humic acid and H. seropedicae (HA + Bac) for 7 days in hydroponic culture. mRNA levels were normalized in relation to the control gene (ubiquitin). Errors were calculated by the REST® program
