OsUCL8 affected pollination and pollen germination. (a) Genomic structure of rice OsUCL8 and constructions of the transgenic plants. (b) Mature spikelet of WT and transgenic plants. Scale bars, 1 mm. (c) Aniline blue staining of pollen tube growth in WT and mutants at 10 min, 20 min, 30 min, 1 h, 2 h after pollination (AP). Scale bars, 100 μm. (d) Reciprocal crosses between OXUCL8 and WT 2hs after artificial pollination, Scale bars, 500 μm. (e) Reciprocal crosses between OXUCL8 and WT 3 d after pollination, Scale bars, 3 mm
