Relative expression levels of PR1 (a), PR2 (b), VvACO1 (c), and GAD1 (d) genes in the leaves of non-inoculated grapevine plantlets (Ctrl), plantlets treated by Pseudomonas chlororaphis Ba47 alone, co-inoculated with Ba47/Gh1 compared with plantlets inoculated with A. tumefaciens Gh1 alone (Ctrl +), and non-treated plantlets (Ctrl-). Results represent the means of three replicates. Vertical bars indicate standard errors (SE) and different letters indicate statistically significant differences between treatments at probability levels of 5%
