a
Line 8 had all floral buds aborted before floral stage 9, which was a representative flowerless plant; Line 27 had all floral buds with no stamens or carpels, which was a representative neuter plant.
b
Flowerless plant: all floral buds were aborted before reaching floral stage 9.
c
Neuter plant: all floral buds had no stamens or carpels.
d
Carpel‐less plant: all flowers had no carpels.
We examined 60 flowers for each wild‐type plant and 100–120 floral buds/ flowers for each transgenic plant.
