Phenotypic analysis of pollen from Zm908-Zm908p11OE, Zm908p-Zm908p11Ri, and wild-type maize plants. (A) Relative expression level of Zm908p11 in transgenic and wild-type maize pollen. (B) In vitro pollen germination efficiency of transgenic and wild-type plants. (C–E) In vitro germination of pollen grains from transgenic and wild-type plants. (C) Pollen grains from Zm908p-Zm908p11OE plants. (D) Pollen grains from wild-type plants. (E) Pollen grains from Zm908p-Zm908p11Ri plants. Pollen grains were cultured in vitro for 3h at 28 °C and 100% humidity in the dark. Bars=100 μm. Error bars represent the mean ±SD; **P < 0.01 (Student’s t-test).
