RT-PCR amplification of BIS1 to BIS4 transcripts in stems (transition zone) and leaves (first living leaf from the top) of cv Holsteiner Cox 6 d after E. amylovora inoculation, and in cell cultures of cv Cox Orange 9 h after treatment with an autoclaved suspension of E. amylovora. Profilin transcript levels served as control for use of equal RNA template amounts.
