Wound-Induced PINII Expression Is Not Compromised in BR Mutants.
Wounding was performed on S. pimpinellifolium, cu3, 35S:Sl BRI1, S. lycopersicum, dx, and abs plants (see Methods). RNA was extracted from systemic unwounded leaves at 0, 2, 4, 8, and 24 h after wounding. Membranes were probed with PINII (top) and reprobed with an 18S rRNA probe (bottom) as a loading control.
