Fruit Set and Parthenocarpy in AS-IAA9 Lines.

(A) Flower buds at 1 d before anthesis in wild-type and AS-IAA9 lines (AS), showing dramatically enlarged ovary and underdeveloped stamen in AS-IAA9 lines.

(B) Precocious fruit development in AS-IAA9.

(C) Wild-type Ailsa Craig seeded fruit (WT AC) and AS-IAA9 parthenocarpic fruit (AS AC). Bars = 10 mm in (A) to (C).

(D) The level of parthenocarpy in AS-IAA9 tomato lines positively correlates with the level of downregulation of the IAA9 gene in independent AS-IAA9 lines. Error bars indicate mean ± se of at least five independent trials, n ≥ 200 fruits.
