a
Number of plants possessing at least one tumor and indication of the respective percentage.
b
(x/y): x is the number of independent pathogenicity tests performed; y is the number of different strains or strain combinations.
c
Plants were inspected 6 to 7 DAI.
d
Plants were inspected 9 to 10 DAI.
e
Tumor with a diameter <1 mm.
f
The majority of tumors (68%) developed after 7 DAI and had diameters of 1 to 3 mm.
