Table 2.
Standardized difference scores (z scores) for genes in each functional class that are significantly differentially expressed in wild-type-inoculated or exoY mutant-inoculated roots
| Functional classes |
z score (observed vs. expected) |
|
|---|---|---|
| Wild-type-inoculated | exoY-inoculated | |
| Pathogenesis/defense | 0.76 | 1.75 (21 vs. 14.5) |
| Unknown function | −3.08 (19 vs. 37.8) | 2.44 (112 vs. 89.3) |
| Ribosome/translation | 8.20 (25 vs. 5.7) | −2.07 (6 vs. 13.4) |
| Protein degradation | 2.01 (13 vs. 7.5) | −0.43 |
| Photosynthesis | 1.99 (4 vs. 1.6) | 0.18 |
| Nodulin, nodulin-like | 1.69 (3 vs. 1.2) | −0.49 |
| Signaling | −1.72 (3 vs. 7.7) | −0.06 |
Positive z scores indicate categories represented at a higher than expected frequency, and negative z scores indicate categories represented at a lower than expected frequency. z scores >1.65 or <−1.65 are significant and shown in bold (90% confidence). See SI Table 6 for values used to calculate z scores.
