Effects of loss of CPK function on signaling pathways for defense response. Effect of exogenous application of JA, ABA or ethephon (an ethylene releasing chemical) on PDF1.2 expression levels after 6 h was investigated. Transcript levels of PDF1.2 in WT, cpk3, and cpk13-1 leaves were expressed relative to the normalized transcript levels in leaves of mock-treated (water-treated or buffer-treated) wild-type plants. Significant differences between treatments were not observed
