Compared with the wild type, GA induction of alpha-amylase activity in aleurone cells of d1 was greatly reduced
IEPA.d192.s461
Relative to the wild type, the GA(3)-treated aleurone layer of d1 had lower expression of Ramy1A, which encodes alpha-amylase, and OsGAMYB, which encodes a GA-inducible transcriptional factor, and no increase in expression of Ca(2 +)-ATPase
IEPA.d192.s462
However, in the presence of high GA concentrations, alpha-amylase induction occurred even in d1
IEPA.d192.s463
All these results suggest that d1 affects a part of the GA-signaling pathway, namely the induction of alpha-amylase in the aleurone layer and internode elongation
