Extended Data Fig. 8: res1 cannot restore the temperature-sensitive male sterility of GFP-tailswap.

a, Fertile phenotypes of Col-0, res1, GFP-tailswap, and GFP-tailswap/res1 plants (22 °C). Scale bar, 5 cm. b, Alexander staining pollen grains of Col-0, res1, GFP-tailswap, and GFP-tailswap/res1 plants, the viable pollen of anthers is stained purple. Twice experiments were repeated independently with similar results. Scale bar, 100 μm.
