Expression of XET-related genes in
genetic mutants exhibiting abnormal heights. Total RNA from two dwarf
mutants, Akibare Dwarf and Waito C, and the overgrowth mutant Awaodori
(lane A, right) was isolated. Ten micrograms of RNA was electrophoresed
in each lane. Lanes C, RNA expression of XTR genes in
wild-type plants. XTR RNA expression was restored in the
two dwarf mutants by treatment with 30 μm GA3
for 12, 24, or 48 h (indicated by numbers at top).
