- Abstract
The extreme dwarf dx tomato (Lycopersicon esculentum Mill.) mutant has very short internodes which were found to contain shorter and fewer epidermal cells. The leaves are highly abnormal. The mutant showed a substantial stem growth response to GA3, without approaching normal stature or morphology. The active gibberellin GA1 and its precursors GA19 and GA20 were identified by coupled gas chromatography-mass spectrometry (GC/MS) in dx shoots. Quantitative GC/MS revealed that GA20, accumulated to far higher levels than normal in stems and leaves of the mutant.
