Floral organ development of glasshouse‐grown rPTAG2I::DT‐A tobacco plants. (a–c) Four‐month‐old rPTAG2I::DT‐A transgenic plants (right) alongside wild type plants (left). Transgenic plants displayed normal vegetative growth and one of three floral ablation phenotypes: flowerless (rPTAG2I::DT‐A‐Line‐8) (a), neuter (stamenless and carpel‐less, rPTAG2I::DT‐A‐Line‐27) (b), or carpel‐less (rPTAG2I::DT‐A‐Line‐35) (c). (d) A closer look at the floral buds from rPTAG2I::DT‐A‐Line‐8. All floral buds were aborted before reaching stage 9 of floral development. (e) A longitudinal section of a floral bud from (d) showing petals, stamens and carpel were aborted. (f) A flower with no stamens or carpels (rPTAG2I::DT‐A‐Line‐27). (g) A longitudinal section of floral buds from rPTAG2I::DT‐A‐Line‐27 having stamens and carpels aborted. (h) A longitudinal section of floral buds from rPTAG2I::DT‐A‐Line‐35 having carpels aborted. (i, j) A longitudinal section of a flower from rPTAG2I::DT‐A‐Line‐35 (j) having carpel aborted when compared to that from a wild type plant (i). se: sepal; pe: petal.
