Effect of the npr1 Mutation on the SA-Mediated Suppression of JA-Responsive Gene Expression.

RNA gel blot analysis of SA-responsive (PR-1) and JA-responsive (LOX2, VSP, and PDF1.2) genes after exogenous application of MeJA, SA, or a combination of both in Arabidopsis wild-type Col-0 and mutant npr1 plants. Five-week-old plants were induced by dipping the leaves in a 0.015% (v/v) Silwet L-77 solution containing 1 mM SA, 0.1 mM MeJA, or a combination of both. Two days later, leaves were harvested for RNA extraction. Equal loading of RNA samples was checked using a probe for the constitutively expressed β-tubulin (TUB) gene.
