From: Characterizing the stress/defense transcriptome of Arabidopsis
Representative northern blot analyses of stress-modulated genes using cloned cDNA fragments from the SSH libraries. (a) Acute ozone treatment; (b) comparison of treatment with salicylic acid, virulent bacteria or avirulent bacteria; (c) chronic ozone treatment; (d) treatment with virulent oomycete. Control leaves (C) were infiltrated with 10 mM MgCl2. Tissue for RNA isolations was harvested at the indicated time points post-treatment.
