Fig. 1From: Rice UCL8, a plantacyanin gene targeted by miR408, regulates fertility by controlling pollen tube germination and growthOsUCL8 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 mmBack to article page
