bHLH003, bHLH013 and bHLH017 Are New Targets of JAZ Repressors Negatively Regulating JA Responses

Resistance of bHLH mutants and OE lines to the bacterial pathogen Pto DC3000.
(A) Growth of Pseudomonas syringae pv. tomato (Pto) DC3000 on WT Arabidopsis plants, jin1-2, coi1-1, bhlh003 and bhlh017 mutants and OE lines for bHLH003, bHLH0013 and bHLH017 3 days after spray inoculation. Bacterial counts are expressed as log (cfu.cm−2). Error bars indicate SE. The results are representative of two independent experiments. Asterisks indicate statistically significant differences compared with WT (Student's t test: *, P<0.05; **, P<0.05; and ***, P<0.001). (B) Disease symptoms in leaves of WT, mutants and OE lines. Pictures of detached leaves were taken 4 days after inoculation.
