Responses in apical hook tissue of Arabidopsis. A)
Fluorescence of the auxin reporter gene DR5::GFP in control (low nutrient medium, LNM) and after treatment
with the ethylene precursor, ACC. B) Differential staining after ACC treatment of the construct carrying the
BR biosynthesis reporter, CPD::GUS,
and its quantification. C) Effects of ACC and BR, alone and in combination, on hook tissue of
wild type (Col-0), the mutant pin3-3,
and the construct 35S::PIN1 in the
dark, and quantification of the hook angle. (Reproduced from De Grauwe et al. 2005, with permission from Professor Van Der Straeten and Oxford University Press.)
