Characterization of bcmf2 transgenic Chinese cabbage. (A) Top and side view of the flowers from empty vector-transformed plants (CK) and bcmf2 transgenic plants. (B) Siliques with seeds of empty vector-transformed plants (CK) and bcmf2 transgenic plants. (C and D) Aniline blue staining of the callose of pollen from empty vector-transformed plants (CK) and bcmf2 transgenic plants. (E and F) Staining of the nuclei of the pollen from empty vector-transformed plants (CK) and bcmf2 transgenic plants. (G and H) In vitro germination showed normal pollen tube growth of the empty vector-transformed plant (CK) and the balloon-tipped pollen tube of the bcmf2 transgenic plants. (I) Comparison of the percentage growth of the pollen tube between the empty vector-transformed plant (CK) and bcmf2 transgenic plants.
