Induction of the PR genes in Arabidopsis in response to infection with A. brassicicola. Four-week-old soil-grown wild-type (Col-0) and ein2-1 plants were infected with A. brassicicola and harvested 48 h following treatment. RNA blots were hybridized with the various probes indicated on the left. Symbols on top of the lanes are as follows: −, Mock-inoculated with water; +, inoculated with A. brassicicola spore suspension; 1°, treated lower rosette leaves; 2°, untreated upper rosette leaves.
