tobacco under a constitutive 35S-promoter. Three lower leaves of plants from the same lines were infected with tobacco mosaic virus (TMV) to study the effect of thenahGgene transcript on SA accumulation. The concentrations of salicylate hydroxylase protein,nahGmRNA, and SA were assayed using leaves...
