Figure 7: Effects of GA on JA biosynthesis mutants.

(a) aos mutant buds were treated with 0.02% ethanol (mock), 50 μM MeJA or 50 μM GA₃ as indicated. The top panel shows representative primary inflorescences. The bottom panel shows representative siliques. Stars indicate siliques rescued by hormone treatment. Scale bar, 10 mm. (b) opr3 mutant buds were treated with 0.02% ethanol (mock), 50 μM MeJA or 50 μM GA₃ as indicated. The top panel shows representative primary inflorescences. The bottom panel shows representative siliques. Stars indicate siliques rescued by hormone treatment. Scale bar, 10 mm. (c) aos siliques rescued by hormone treatment. Stars indicate rescued seeds. Scale bar, 1 mm.
