Phenotypic characterization of the flo14 mutant. a Comparison of wild-type (WT) and flo14 mutant (flo14) seeds. b Cross sections of wild-type and flo14 mutant seeds. c Vertical-sections of imbibed embryos of wild type and flo14 mutant. d Tetrazolium assay of wild-type and flo14 mutant seeds. e Young seedlings of wild type and flo14 mutant at 5 days after germination. f Thousand kernel weight of wild-type and flo14 mutant seeds. Data indicate means ± SD (from at least three independent samples) and was compared with wild type by Student’s t-test (* P < 0.05, ** P < 0.01). Scale bars: 1 mm in (a and b), 1 cm in (c and d), 500 μm in (e)
