Colonization by wild-type (WT), SM1-deletion (KO), or SM1-overexpression (OE) strains of maize seedlings grown in hydroponic system or in soil
| Strain | Hydroponicsa | Soilb |
|---|---|---|
| WT | 94.40 ± 1.88 | 1.92 ± 0.21 |
| KO25 | 97.25 ± 0.64 | 2.57 ± 0.21 |
| KO46 | 96.15 ± 1.29 | 1.96 ± 0.15 |
| OE38 | 95.02 ± 0.91 | 1.98 ± 0.38 |
| OE39 | 94.83 ± 1.46 | 2.12 ± 0.32 |
a
The percentage of the total length of excised root fragments from the hydroponic system colonized by the strains of T. virens given as a mean of six replicates with the se.
b
Total number of colonies of the strains per centimeter of root harvested from the maize seedling grown in soil given as a mean of five replicates with the se. These experiments were replicated at least once with similar results. Based on ANOVA (P < 0.05), there was no significant differences in root colonization in any of the growth systems.
