Characterization of new gibberellin-responsive semidwarf mutants of arabidopsis.

Plant physiology - 1 Nov 1997

Abstract excerpt

Chemical mutagenesis of Arabidopsis thaliana (L.) Heynh. yielded four semidwarf mutants, all of which appeared to be gibberellin (GA)-biosynthesis mutants. All four had atypical response profiles to C20-GAs, suggesting that each had impaired 20-oxidation. One mutant, 11.2, was shown to be allelic to ga5 and has been named ga5-2. It had altered metabolism of [14C]GA15 relative to that in wild-type plants and...
