k-means clustering of 4243 genes Psa into 6 groups. HPI, hours post infection
| Group | k-means clade | Number of genes | Description | Expression Phase |
|---|---|---|---|---|
| 1 | 1 & 13 | 1137 | Constitutively expressed genes | N/A |
| 2 | 2,3, & 4 | 1323 | Genes down-regulated in planta | N/A |
| 3 | 5 | 815 | Little differential expression compared to in vitro | N/A |
| 4 | 6, 10 & 11 | 311 | Genes upregulated (3–24 HPI) in planta | Mid |
| 5 | 7,8, & 9 | 550 | Genes upregulated late (48–120 HPI) in planta | Late |
| 6 | 12 | 107 | Early upregulated (1.5–3 HPI) genes in planta | Early |
