Data were collected from a representative RT-PCR amplification of three independent replicates. Ctrl indicates the untreated controls. JA, ACC, and JA+ACC indicate the different phytohormone treatments. Native indicates the number of colonies containing native PR3b fragments. Spliced indicates the number of colonies containing alternatively spliced PR3b fragments.
