Phenotypic effects of mutations in Fragaria × ananassa TM6 (FaTM6) in fruits and in a complementation experiment. (A) Wild-type flowers emasculated at the pre-anthesis stage phenocopy aborted flowers in tm6 mutant lines. Two representative flowers per genotype are shown. (B) Top panels: adult plants of control and tm6 mutant lines. Bottom panels: control plants develop wild-type berries, but tm6 flowers abort. (C) SEM of the structures of carpels at the pre-anthesis stage. (D) A fruit developed from a tm6-7 flower emasculated and pollinated with wild-type pollen. Scale bars: (A) 1 cm; (C) 200 µm.
