Fig. 1. Shoot gene expression (in relative units) of maize aquaporins in non-inoculated plants (C), plants singly inoculated with Bacillus thuringiensis (Bt) or with AM fungi (AM) or
coinoculated with both microorganisms (AM þ Bt) under well-watered conditions. Values having a different letter are significantly different (p 0.05) as determined by Duncan's
multiple-range test.
