BcMF8 inhibition specifically disrupted the in vitro pollen tube growth and affected seed set. (A) Pollen from empty vector pBI121-transformed plants (CK) was normal. (B–D) Pollen from the bcmf8 lines was abnormal. The pollen tubes of the bcmf8 lines were balloon-tipped (B), bead-like (C) or burst-tipped (D). (E) The germination percentage (± s.e.) of the bcmf8 pollen. (F) The bcmf8 siliques produced significantly fewer seeds than those of CK. Mean seed numbers (± s.e.) per silique of the bcmf8 lines are shown. Scale bars = 20 µm (A–D).
