Functional validation and expression analysis of OsC1 and OsDFR. a The straw-white apiculi became brown whereas stigmas remained straw-white after OsC1 was introduced into Kitaake. The top, spikelets 1 day post heading; the bottom, spikelets 14 days post heading. Bars, 2 mm. b Both apiculus and stigma became purple when both OsC1 and OsDFR were transformed into Kitaake. The top, spikelets 1 day post heading; the bottom, spikelets 14 days post heading. Bars, 2 mm. c Expression levels of OsC1 and OsDFR in Kitaake and complementation plants. C#1, C#2, two independent OsC1-complemented lines. CD#1, CD#2, two independent complemented lines with OsC1 and OsDFR. Data are means ± SD of three biological replicates (Student’s t-test: **P < 0.01)
