Ethylene Signaling Promotes hub1 Susceptibility to A. brassicicola but Is Required for Resistance to Botrytis.

Disease assays on hub1, ein2, and hub1ein2 double mutant showing A. brassicicola disease symptoms (A), size of disease lesion ([B]; left) and fungal growth (right), B. cinerea disease symptoms (C), and fungal growth (D). In (D), total RNA (10 μg) was loaded per lane. All disease assays were repeated at least twice. Data in (B) represent mean ± se from at least 30 lesions. Bc ActinA, B. cinerea ActinA gene; d, days after inoculation.
