Fig 6. Zinc level and bacterial presence interact to regulate root length in an AZI1 dependent fashion.

Fig 6

Root lengths of Col-0, Sq-1, azi1-1 and azi1-2 seedlings grown with Azospirillum brasilense (Sp245) on +Zn or –Zn medium for five days. Letters indicate significantly different values at p <0.05 determined by ANOVA and Tukey HSD. Multi-factorial ANOVA was used to test the impact of genotype (Col-0, Sq-1 and azi1 (azi1-1, azi1-2)), treatment (+Zn, -Zn, +BactSp245, -BactSp25) and their interaction on primary root length. The ANOVA results are presented in the table. Significative codes: ‘***’ 0.001.
