CBNAC expression is induced by pathogen- and SA. (A) Induction of CBNAC gene expression by PstDC3000. Leaves of 4-week-old Arabidopsis plants (Col-0) were infiltrated with a bacterial suspension (OD₆₀₀ = 0.001 in 10 mM MgCl₂). Infitrated leaves were harvested at the indicated times after inoculation. The gel blot analysis of total RNA that was performed with a ³²P-labeled CBNAC probe is shown. Ethidium bromide-stained rRNA is shown as loading control. (B) Induction of CBNAC gene expression by SA. Leaves of 4-week-old Arabidopsis plants (Col-0) were treated with 1 mM SA. Leaf collection, RNA isolation and RNA gel blot analysis was performed as in (A).
