Hormone contents and relative gene expression levels impacted by Cladosporium fulvum treatment at the time points of 24 hours. (A) The contents of SA, ABA and JA in tomato leaves were detected 24 hours after sprayed exogenously with a conidial suspension (1X10⁶ conidia/ml) of C fulvum, water treatment as a control. Shown are the mean and SE of three biological replicates. Statistical differences were determined Student’s t-test (p<0.05). (B) Six genes related to plant hormone signal transduction pathway were tested expression level by C fulvum inoculation after 24 hours. SlNPR1 and SlPR1 are SA-related pathway genes, SlSRK2C and SlPYR1 are ABA-related pathway genes, SlLoxC and SlAOC are JA-related pathway genes. The qRT-PCR values represent mean ± SE from three biological replicates. * indicate signifificant differences between control and C.fulvum with p < 0.05, as determined by t-test.
