RNAi silencing of TAG1 produces defects in stamens and affects floral determinacy. (A) Control flower ∼3 dpa. (B) TAG1 RNAi line 4 flower made using a shorter (262 bp) fragment for silencing. (C) TAG1 RNAi line 7 flower made using a longer (430 bp) fragment for silencing. (D) TAG1 RNAi line 2 with the ‘fruit inside fruit’ phenotype. (E) Control (left) and TAG1 RNAi line 7 (right) carpels. (F) Control (left) and TAG1 RNAi line 7 (right) stamens showing petalloid tissue. (G) Control red, ripe fruit. (H) Range of phenotypes of TAG1 RNAi line 7 fruit: (top) ectopic exocarp tissue, (bottom left) ‘fruit inside fruit’ (bottom centre and right) internal flower structures.
