Leaves were infiltrated with 107 CFU per mL or, as a control, mock infiltrated with 10 mm MgCl2. For a description of the different transgenics and/or mutants, see the text. The AOX transcript level of the control (mock-treated) leaves of the wild type is set at 1. For wild-type and NahG plants, PR-1 transcript levels are presented in parentheses, with control (mock-treated) leaves of the wild type set at 1.
a
ND, Not detectable. mRNA from this tissue could no longer be isolated because of complete necrosis.
b
–, Not determined.
