TABLE 2.
Results of internal leaf tissue and phyllosphere antagonism experiments measuring X. euvesicatoria strain E3-1 populations when coinoculated with water, X. euvesicatoria strain E3-1, or WT or mutant X. perforans strain 91-118, measured as the AUPPC
| Treatment | AUPPCa
|
|
|---|---|---|
| Internal antagonism | Phyllosphere antagonism | |
| Water control | 115.3 (a)b | |
| X. euvesicatoria 91-106 | 101.7 (b) | 120.8 (a) |
| X. perforans 91-118 | 67.0 (d) | 69.0 (c) |
| X. perforans 91-118::ΔopgHΔbcnB | 90.8 (c) | 86.3 (b) |
a
AUPPC values are from assays of antagonism over a 96-h period based on recovered populations of X. euvesicatoria strain E3-1.
b
Values followed by the same letter are not significantly different based on the Waller-Duncan multiple-range test (P = 0.05).
