Dominant-Negative Effect of POD1RXRRR>RXAAA and POD1ΔLR.
(A) Micrograph showing defective pollen tube guidance and abnormal morphology in POD1RXRRR>RXAAA transgenic plants.
(B) Micrograph showing defective pollen tube guidance and abnormal morphology in POD1ΔLR transgenic plants.
Arrowhead, micropyle; arrow, pollen tube. Limited pollen grains from POD1RXRRR>RXAAA and POD1ΔLR transgenic plants were pollinated onto the wild-type stigma. Bars = 100 μm.
