Effect of AA on young fruit development. Young
tomato fruits attached to the plant were injected with a control or AA
solution. Groups of three to five fruits were collected after 3 d
or 1 month and used for experiments. A, Fruit weight 1 month after
treatment with different concentrations of AA. B, Fruit samples from
the experiment shown in C. C, Fruit weight 3 d after injection of
4 μL of a control solution or 5 μg/μL AA solution. Columns
represent means and bars represent sd values. D, RNA blot
of total RNA samples from the fruit samples shown in C. The same blot
was hybridized with gene-specific HMG1,
HMG2, and 18S rRNA probes.
