This table does not contain the data from susceptible plants because on Gala and transgenic Ga2-7 leaf samples the new stroma and conidiophores were too dense, making conidia counting impossible.
For each plant, one leaf section (≈1.5 × 1 cm) was examined.
Fungal development for each conidium was defined according to the following classes: α, isolated areas of stroma with sporulating conidiophores; β, primary stroma expanding no more than ≈40 μm; and γ, no fungal development beyond that of appressoria and penetration peg.
